In liver transplant recipients or patients with autoimmune hepatitis on immunosuppressive therapy, acute cellular rejection or disease flare should not be presumed in the face of active coronavirus disease 2019 (COVID-19), according to the American Association for the Study of Liver Diseases (AASLD).

Signs that would normally be interpreted as flare or rejection need to be considered more cautiously now because the virus attacks the liver, and elevated aspartate aminotransferase, alanine aminotransferase, and slightly elevated bilirubin are common, ranging from a prevalence of 14% to 53% in COVID-19 patients. Acute liver injury is possible, especially in more severe cases, the group said.

The advice comes from a recently released document from AASLD, called “Clinical Insights for Hepatology and Liver Transplant Providers During the Covid-19 Pandemic,” to help hepatologists and liver transplant providers negotiate the pandemic, according to the latest data. It’s a far-ranging work that contains a lot of now familiar steps for providers to take to protect themselves and patients from the virus, but also much advice specific to liver medicine.

For instance, the group said it’s important to keep in mind that experimental treatments for the infection, including statins, remdesivir, and tocilizumab, can be hepatotoxic. Abnormal liver biochemistries are not a contraindication, but liver biochemistries need to be followed regularly in COVID-19 patients, especially those treated with remdesivir or tocilizumab, regardless of baseline values.

Also, lopinavir/ritonavir is a potent inhibitor of cytochrome P450 enzymes involved with calcineurin inhibitor metabolism, so if it’s used, AASLD said to reduce tacrolimus dosages to 1/20–1/50 of baseline.

The group cautioned against anticipatory adjustments to immunosuppressive drugs or dosages in patients without COVID-19, but if immunosuppressed liver disease patients do get the infection, prednisone doses should be reduced but kept above 10 mg/day to avoid adrenal insufficiency. In the setting of lymphopenia, fever, or worsening COVID-19 pneumonia, it advised reduction of azathioprine and mycophenolate dosages and reduction of, but not stopping, calcineurin inhibitors.

Liver transplants should not be postponed. However, to minimize exposure to the hospital environment, AASLD advised to “consider evaluating only patients with HCC [hepatocellular carcinoma] or those patients with severe disease and high MELD [model for end-stage liver disease] scores who are likely to benefit from immediate liver transplant.”

“An argument that has been put forward to justify deferring some transplants is concern about immunosuppressing patients during the COVID-19 pandemic,” the group said, but “data suggest the innate immune response may be the main driver for pulmonary injury due to COVID-19 and [that] immunosuppression may be protective. ... Posttransplant immunosuppression was not a risk factor for mortality associated with” the severe acute respiratory syndrome pandemic in 2003-2004 or the ongoing Middle East respiratory syndrome pandemic, both also caused by coronaviruses.

AASLD advised against reducing immunosuppression or stopping mycophenolate for asymptomatic patients after transplant, but COVID-19 prevention measures should be emphasized, including frequent hand washing and staying away from large crowds.

People who test positive for COVID-19 are ineligible for organ donation. Bronchoalveolar lavage is the most sensitive test (93%), followed by nasal swabs (63%) and pharyngeal swabs (32%).

In general, the group said elective procedures should be postponed, but urgent ones, such as biliary surgery and transjugular intrahepatic portosystemic shunts for bleeding varices, in addition to liver transplants, should not.

Also, HCC patients “should not wait until the pandemic abates to undergo [surveillance] imaging because the prospective duration of the pandemic is unknown. ... An arbitrary delay of 2 months is reasonable” for imaging based on patient and facility circumstances, but otherwise, “proceed with HCC treatments rather than delaying them due to the pandemic,” the group said.

As for who to bring into the office for an initial consult, “consider seeing in person only new adult and pediatric patients with urgent issues and clinically significant liver disease (e.g., jaundice, elevated ALT or AST above 500 U/L, recent onset of hepatic decompensation),” AASLD said.

Medical oncologist Anne Chiang, MD, PhD, is scrambling to maintain cancer care in New Haven, Connecticut, while COVID-19 advances unrelentingly. As deputy chief medical officer of the Smilow Cancer Network, the largest cancer care delivery system in Connecticut and Rhode Island, she has no illusions about dodging what’s unfolding just 2 hours down the road in New York City.

“They’re trying their best to continue active cancer treatment but it’s getting harder,” she says of her colleagues in the thick of the pandemic. “We have to be prepared for it here.”

In anticipation of what’s coming, her team has just emptied the top three floors of the Smilow Cancer Hospital, moving 60 patients by ambulance and other medical transport to a different hospital nearby.

The move frees the Smilow Cancer hospital’s negative-pressure wards for the anticipated wave of COVID-19 patients. It will keep the virus sealed off from the rest of the hospital. But in other locations it’s harder to shield patients with cancer from the infection.

Around the state, Smilow Cancer Network’s affiliated hospitals are already treating a growing number of COVID-19 patients, especially at Greenwich Hospital, right on the border with New York state.

To protect patients with cancer, who are among the most vulnerable to the virus, oncologists are embracing telemedicine to allow most patients to stay home.

“We’re really concentrating on decreasing the risk to these patients, with a widespread massive-scale conversion to telehealth,” said Chiang. “This is something that, in the space of about a week, has transformed the care of our patients — it’s a really amazing transformation.”

If anything good comes out of the COVID-19 pandemic, it will be this global adoption of virtual healthcare.

Across the US border in Canada, the medical director of Toronto’s Princess Margaret Cancer Centre is directing a similar transformation.

“We have converted probably about 70% to 80% of our clinic visits to virtual visits,” says radiation oncologist Mary Gospodarowicz, MD.

“We have three priorities: number one, to keep our patients safe; number two, to keep our staff safe, because if staff are sick we won’t be treating anybody; and number three, to treat as many patients with cancer as possible.”

Gospodarowicz woke up last week to a local headline about a woman whose mastectomy had been canceled “because of the coronavirus.” The story exposed the many layers of the COVID-19 crisis. “A lot of hospitals have canceled elective surgeries,” she acknowledged. “For patients who have treatment or surgery deferred, we have a database and we’ll make sure we look after those patients eventually. We have a priority system, so low-risk prostate cancer, very low-risk breast cancer patients are waiting. All the urgent head and neck, breast, and other higher priority surgeries are still being done, but it just depends how it goes. The situation changes every day.”

It’s similar in Los Angeles, at the University of Southern California, says Elizabeth David, MD, a cardiothoracic surgeon with Keck Medicine.

“For thoracic, we just had a conference call with about 30 surgeons around the country going through really nitty-gritty specifics to help with our decision making about what could wait without detriment to the patient – hopefully – and what should be done now,” she told Medscape Medical News.

“There are some hospitals where they are not doing anything but life and death emergency operations, whereas we are still doing our emergent cancer operations in our institution, but we all know – and patients know – that could change from one day to the next. They may think they’re having surgery tomorrow but may get a call saying we can’t do it,” David said.

Many of David’s patients have non–small cell lung cancer, putting them at particular risk with a pulmonary infection like COVID-19. For now, she says delivery of postsurgical chemotherapy and radiotherapy has not been impacted in her area, but her videoconference discussions with patients are much longer – and harder – these days.

“I’ve been in practice a while now and I’ve had numerous conversations with patients this week that I never trained for, and I’ve never known anyone else who has. It’s really hard as a provider to know what to say,” she said.

In cardiothoracic surgery, David said guidance on clinical decision making is coming from the American College of Surgeons, Society of Thoracic Surgery, and American Association of Thoracic Surgeons. Yet, she says each patient is being assessed – and reassessed – individually.

“You have to balance the risk of delaying the intervention with supply issues, hospital exposure issues, the danger to the patient of being in the hospital environment – there’s just so many factors. We’re spending so much time talking through cases, and a lot of times we’re talking about cases we already talked about, but we’re just making sure that based on today’s numbers we should still be moving forward,” she commented.

In Connecticut, Chiang said treatment decisions are also mostly on a case-by-case basis at the moment, although more standardized guidelines are being worked out.

“Our disease teams have been really proactive in terms of offering alternative solutions to patients, creative ways to basically keep them out of the hospital and also reduce the immunosuppressive regimens that we give them,” she said.

Examples include offering endocrine therapy to patients who can’t get breast cancer surgery, or offering alternative drug regimens and dosing schedules. “At this point we haven’t needed to ration actual treatment – patients are continuing to get active therapy if that’s appropriate – it’s more about how can we protect them,” she said. “It’s a complex puzzle of moving pieces.”

In Toronto, Gospodarowicz says newly published medical and radiation oncology guidelines from France are the backbone of her hospital’s policy discussions about treating cancer and protecting patients from COVID-19.

While patients’ concerns are understandable, she says even in the current hot spots of infection, it’s encouraging to know that cancer patients are not being forgotten.

“I recently had email communication with a radiation oncologist in Brescia, one of the worst-affected areas in Italy, and he told me the radiotherapy department has been 60% to 70% capacity, so they still treat 70% these patients, just taking precautions and separating the COVID-positive and negative ones. When we read the stats it looks horrible, but life still goes on and people are still being treated,” she said.

Although telemedicine offers meaningful solutions to the COVID-19 crisis in North America, it may not be possible in other parts of the world.

Web consultations were only just approved in Brazil this week. “We are still discussing how to make it official and reimbursed,” says Rachel Riechelmann, MD, head of clinical oncology at AC Camargo Cancer Center in São Paulo.

To minimize infection risk for patients, Riechelmann says her hospital is doing the following: postponing surgeries in cases where there is good evidence of neoadjuvant treatment, such as total neoadjuvant therapy for rectal cancer; avoiding adjuvant chemo for stage 2 colon cancer; moving to hypofractionated radiotherapy if possible; adopting watchful waiting in grade 1 nonfunctional neuroendocrine tumors; and postponing follow-up visits.

“We do our best,” she wrote in an email. “We keep treating cancer if treatment cannot wait.”

Riechelmann’s center has just launched a trial of hydroxychloroquine and tocilizumab therapy in patients with cancer who have severe COVID-19 and acute respiratory distress syndrome (ARDS).

Meanwhile in New Haven, Chiang says for patients with cancer who are infected with COVID-19, her team is also prognosticating about the fair allocation of limited resources such as ventilators.

“If it ever gets to the point where somebody has to choose between a cancer patient and a noncancer patient in providing life support, it’s really important that people understand that cancer patients are doing very well nowadays and even with a diagnosis of cancer they can potentially live for many years, so that shouldn’t necessarily be a decision-point,” she emphasized.

“If it ever gets to the point where somebody has to choose between a cancer patient and a noncancer patient in providing life support, it’s really important that people understand that cancer patients are doing very well nowadays and even with a diagnosis of cancer they can potentially live for many years, so that shouldn’t necessarily be a decision-point,” she emphasized.

The Food and Drug Administration has approved safety labeling changes to all sodium-glucose transporter 2 (SGLT2) inhibitors used to treat high blood sugar in patients with type 2 diabetes.

The new changes affect canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin, and were made because surgery may put patients being treated with SGLT2 inhibitors at a higher risk of ketoacidosis. Canagliflozin, dapagliflozin, and empagliflozin should be discontinued 3 days before scheduled surgery, and ertugliflozin should be stopped at least 4 days before, the agency noted in a press release. Blood glucose should be monitored after drug discontinuation and appropriately managed before surgery.

“The SGLT2 inhibitor may be restarted once the patient’s oral intake is back to baseline and any other risk factors for ketoacidosis are resolved,” the agency added.

SGLT2 inhibitors lower blood sugar by causing the kidney to remove sugar from the body through urine. Side effects for the drugs vary, but include urinary tract infections and genital mycotic infection. Patients with severe renal impairment or end-stage renal disease, who are on dialysis treatment, or who have a known hypersensitivity to the medication should not take SGLT2 inhibitors, the FDA said.

MAUI, HAWAII – If an intra-abdominal abscess in a recently diagnosed Crohn’s disease patient is less than 6 cm across with no downstream stenosis, involves only a short segment of bowel, and the patient has no perianal disease, then infliximab and azathioprine after drainage and antibiotics might be enough to heal it, according to Miguel Regueiro, MD, chair of the department of gastroenterology, hepatology, and nutrition at the Cleveland Clinic.

M. Alexander Otto/MDedge News

That will work in about 30% of patients who hit the mark; the rest will eventually need surgery, said Dr. Regueiro, a clinical researcher who has worked extensively with surgical GI patients and is also a coauthor on the American College of Gastroenterology 2018 Crohn’s disease guidelines (Am J Gastroenterol. 2018 Apr;113[4]:481-517).

Intra-abdominal abscesses are common in Crohn’s, usually from an inflammation-induced fistula or sinus in the small intestines that spills luminal contents into the abdominal cavity. Drainage and antibiotics are first line, but then there’s the question of who needs to go to the operating room and who doesn’t.

It has to do with “how much the hole in the intestines is actually reversible. Evidence of a stricture is of paramount importance. If you have a stricture below a fistula and prestenotic dilatation, that’s a high-pressure zone.” It’s a “fixed complication that, in my opinion, no medication is ever going to treat,” he said at the Gastroenterology Updates, IBD, Liver Disease Conference.

Most patients will need surgery, but for smaller abscesses in qualifying patients, medical treatment can work. “Infliximab is still probably the best medicine for fistulizing disease,” so Dr. Regueiro opts for that if patients haven’t been on it before, in combination with an immunomodulator, generally azathioprine at half the standard dose, to prevent patients from forming antibodies to the infliximab.

When patients do go to the operating room, there is a good chance they will end up with a temporary ostomy, and definitely so if the abscess can’t be drained completely to prevent spillage. The risk of dehiscence and other complications is too great for primary anastomosis.

“I mentally prepare my patients for that; I tell them up front. I never guarantee that they are not going to have an ostomy bag,” Dr. Regueiro said.

He also said abscess formation isn’t necessarily a sign the biologic patients were on before has failed, especially if they were only on it for 6 months or so. More likely, “the disease was too far gone at that point” for short-term treatment to have much of an effect.

So he’s often likely to continue patients on the same biologic after surgery. “We’ve done a lot of study on” this and have “actually found that” patients do well with the approach. He will switch treatment, however, if they otherwise no longer seem to respond to a biologic they have been taking a while, despite adequate serum levels.

There’s no need to delay surgery for patients on biologics. “If they get a biologic the day before, they can still go to the [operating room]. We are not seeing increased postop complications, infections, or wound dehiscence,” he said.

Dr. Regueiro generally restarts biologics 2-4 weeks after surgery, which is enough time to know if there is going to be a surgical complication but not so long that patients will have a Crohn’s relapse. He restarts the maintenance dose, as “it’s not necessary to reinduct patients after such a short break,” he said.

He also noted that opioids and steroids should be avoided with Crohn’s abscesses. Opioids increase the risk of ileus, and steroids the risk of sepsis.

The U.S. Multi-Society Task Force on Colorectal Cancer (CRC) recently updated recommendations for patient follow-up after colonoscopy and polypectomy.

The new guidance was based on advancements in both research and technology since the last recommendations were published in 2012, reported lead author Samir Gupta, MD, AGAF, of the University of California, San Diego, and colleagues.

“[Since 2012,] a number of articles have been published on risk of CRC based on colonoscopy findings and patient characteristics, as well as the potential impact of screening and surveillance colonoscopy on outcomes, such as incident CRC and polyps,” the investigators wrote in Gastroenterology. “Further, recent studies increasingly reflect the modern era of colonoscopy with more awareness of the importance of quality factors (e.g., adequate bowel preparation, cecal intubation, adequate adenoma detection, and complete polyp resection), and utilization of state of the art technologies (e.g., high-definition colonoscopes).”

The task force, which comprised the American College of Gastroenterology, the American Gastroenterological Association, and the American Society of Gastrointestinal Endoscopy, identified key topics using PICO (patient, intervention, comparison, and outcome) questions before conducting a comprehensive literature review that included 136 articles. Based on these findings, two task force members generated recommendations that were further refined through consensus discussion. The recommendations were copublished in the March issues of the American Journal of Gastroenterology, Gastroenterology, and Gastrointestinal Endoscopy.

According to Dr. Gupta and colleagues, some of the new recommendations, particularly those that advise less stringent follow-up, may encounter resistance from various stakeholders.

“Patients, primary care physicians, and colonoscopists may have concerns about lengthening a previously recommended interval, and will need to engage in shared decision making regarding whether to lengthen the follow-up interval based upon the guidance here or utilize the recommendation made at the time of the prior colonoscopy,” the task force wrote.

The most prominent recommendations of this kind concern patients who undergo removal of tubular adenomas less than 10 mm in size. For patients who have 1-2 of these adenomas removed, the task force now recommends follow-up after 7-10 years, instead of the previously recommended interval of 5-10 years.

“[This decision was] based on the growing body of evidence to support low risk for metachronous advanced neoplasia,” the task force wrote. “In this population, the risk for metachronous advanced neoplasia is similar to that for individuals with no adenoma. Importantly, the observed risk for fatal CRC among individuals with 1-10 adenomas less than 10 mm is lower than average for the general population.”

Along similar lines, patients who undergo removal of 3-4 small adenomas now have a recommended 3-5 year follow-up window, instead of the previously strict recommendation for follow-up at 3 years.

But not all of the new guidance is less stringent. While the task force previously recommended a follow-up period of less than 3 years after removal of more than 10 adenomas, they now recommend follow-up at 1 year. This change was made to simplify guidance, the investigators wrote, noting that the evidence base in this area “has not been markedly strengthened” since 2012.

Compared with the old guidance, the updated publication offers more detailed recommendations for follow-up after removal of serrated polyps. On this topic, 10 clinical scenarios are presented, with follow-up ranging from 6 months after piecemeal resection of a sessile serrated polyp greater than 20 mm to 10 years after removal of 20 or fewer hyperplastic polyps less than 10 mm that were located in the rectum or sigmoid colon. Incidentally, these two recommendations are strong and based on moderate evidence, whereas the remaining recommendations for serrated polyps are weak and based on very-low-quality evidence.

Because of such knowledge gaps, the investigators emphasized the need for more data. The publication includes extensive discussion of pressing research topics and appropriate methods of investigation.

“Our review highlights several opportunities for research to clarify risk stratification and management of patients post-polypectomy,” the task force wrote. “In order to optimize risk-reduction strategies, the mechanisms driving metachronous advanced neoplasia after baseline polypectomy and their relative frequency need to be better understood through studies that include large numbers of patients with interval cancers and/or advanced neoplasia after baseline polypectomy. Mechanisms may include new/incident growth, incomplete baseline resection, and missed neoplasia; each of these potential causes may require different interventions for improvement.”

The task force also suggested that some basic questions beyond risk stratification remain unanswered, such as the impact of surveillance on CRC incidence and mortality.

“Such evidence is needed given the increasing proportion of patients who are having adenomas detected as part of increased participation in CRC screening,” the task force wrote.

Other suggested topics of investigation include age-related analyses that incorporate procedural risk, cost-effectiveness studies, and comparisons of nonendoscopic methods of surveillance, such as fecal immunochemical testing.

The study was funded by the National Institutes of Health and the Department of Veterans Affairs. The investigators reported relationships with Covidien, Ironwood, Medtronic, and others.

The U.S. Multi-Society Task Force (USMSTF) on Colorectal Cancer recently published recommendations for endoscopic removal of precancerous colorectal lesions.

According to lead author Tonya Kaltenbach, MD, of the University of California, San Francisco, and fellow panelists, the publication aims to improve complete resection rates, which can vary widely between endoscopists; almost one out of four lesions (22.7%) may be incompletely removed by some practitioners, leading to higher rates of colorectal cancer.

“[A]lthough the majority (50%) of postcolonoscopy colon cancers [are] likely due to missed lesions, close to one-fifth of incident cancers [are] related to incomplete resection,” the panelists wrote in Gastroenterology, referring to a pooled analysis of eight surveillance studies.

The panelists’ recommendations, which were based on both evidence and clinical experience, range from specific polyp removal techniques to guidance for institution-wide quality assurance of polypectomies. Each statement is described by both strength of recommendation and level of evidence, the latter of which was determined by Grading of Recommendations, Assessment, Development, and Evaluation Ratings of Evidence (GRADE) criteria. Recommendations were written by a panel of nine experts and approved by the governing boards of the three societies they represented – the American College of Gastroenterology, the American Gastroenterological Association, and the American Society for Gastrointestinal Endoscopy. The recommendations were copublished in the March issues of the American Journal of Gastroenterology, Gastroenterology, and Gastrointestinal Endoscopy. 

Central to the publication are recommended polypectomy techniques for specific types of lesions.

“Polypectomy techniques vary widely in clinical practice,” the panelists wrote. “They are often driven by physician preference based on how they were taught and on trial and error, due to the lack of standardized training and the paucity of published evidence. In the past decade, evidence has evolved on the superiority of specific methods.”

“Optimal techniques encompass effectiveness, safety, and efficiency,” they wrote. “Colorectal lesion characteristics, including location, size, morphology, and histology, influence the optimal removal method.”

For lesions up to 9 mm, the panelists recommended cold snare polypectomy “due to high complete resection rates and safety profile.” In contrast, they recommended against both cold and hot biopsy forceps, which have been associated with higher rates of incomplete resection. Furthermore, they cautioned that hot biopsy forceps may increase risks of complications and produce inadequate tissue samples for histopathology.

For nonpedunculated lesions between 10 and 19 mm, guidance is minimal. The panelists recommended cold or hot snare polypectomy, although this statement was conditional and based on low-quality evidence.

Recommendations were more extensive for large nonpedunculated lesions (at least 20 mm). For such lesions, the panelists strongly recommended endoscopic mucosal resection (EMR). They emphasized that large lesions should be removed in the fewest possible pieces by an appropriately experienced endoscopist during a single colonoscopy session. The panelists recommended the use of a viscous injection solution with a contrast agent and adjuvant thermal ablation of the post-EMR margin. They recommended against the use of tattoo as a submucosal injection solution, and ablation of residual lesion tissue that is endoscopically visible. Additional recommendations for large lesions, including prophylactic closure of resection defects and coagulation techniques, were based on low-quality evidence.

For pedunculated lesions greater than 10 mm, the panelists recommended hot snare polypectomy. For pedunculated lesions with a head greater than 20 mm or a stalk thickness greater than 5 mm, they recommended prophylactic mechanical ligation.

Beyond lesion assessment and removal, recommendations addressed lesion marking, equipment, surveillance, and quality of polypectomy.

Concerning quality, the panelists recommended that endoscopists participate in a quality assurance program that documents adverse events, and that institutions use standardized polypectomy competency assessments, such as Cold Snare Polypectomy Competency Assessment Tool and/or Direct Observation of Polypectomy Skills.

“Focused teaching is needed to ensure the optimal endoscopic management of colorectal lesions,” the panelists wrote. They went on to suggest that “development and implementation of polypectomy quality metrics may be necessary to optimize practice and outcomes.”

“For example, the type of resection method used for the colorectal lesion removal in the procedure report should be documented, and the inclusion of adequate resection technique as a quality indicator in colorectal cancer screening programs should be considered,” they wrote. “Adverse events, including bleeding, perforation, hospital admissions, and the number of benign colorectal lesions referred for surgical management, should be measured and reported. Finally, standards for pathology preparation and reporting of lesions suspicious for submucosal invasion should be in place to provide accurate staging and management.”

The U.S. Multi-Society Task Force (USMSTF) on Colorectal Cancer recently published recommendations for endoscopic removal of precancerous colorectal lesions.

According to lead author Tonya Kaltenbach, MD, of the University of California, San Francisco, and fellow panelists, the publication aims to improve complete resection rates, which can vary widely between endoscopists; almost one out of four lesions (22.7%) may be incompletely removed by some practitioners, leading to higher rates of colorectal cancer.

“[A]lthough the majority (50%) of postcolonoscopy colon cancers [are] likely due to missed lesions, close to one-fifth of incident cancers [are] related to incomplete resection,” the panelists wrote in Gastroenterology, referring to a pooled analysis of eight surveillance studies.

The panelists’ recommendations, which were based on both evidence and clinical experience, range from specific polyp removal techniques to guidance for institution-wide quality assurance of polypectomies. Each statement is described by both strength of recommendation and level of evidence, the latter of which was determined by Grading of Recommendations, Assessment, Development, and Evaluation Ratings of Evidence (GRADE) criteria. Recommendations were written by a panel of nine experts and approved by the governing boards of the three societies they represented – the American College of Gastroenterology, the American Gastroenterological Association, and the American Society for Gastrointestinal Endoscopy. The recommendations were copublished in the March issues of the American Journal of Gastroenterology, Gastroenterology, and Gastrointestinal Endoscopy. 

Central to the publication are recommended polypectomy techniques for specific types of lesions.

“Polypectomy techniques vary widely in clinical practice,” the panelists wrote. “They are often driven by physician preference based on how they were taught and on trial and error, due to the lack of standardized training and the paucity of published evidence. In the past decade, evidence has evolved on the superiority of specific methods.”

“Optimal techniques encompass effectiveness, safety, and efficiency,” they wrote. “Colorectal lesion characteristics, including location, size, morphology, and histology, influence the optimal removal method.”

For lesions up to 9 mm, the panelists recommended cold snare polypectomy “due to high complete resection rates and safety profile.” In contrast, they recommended against both cold and hot biopsy forceps, which have been associated with higher rates of incomplete resection. Furthermore, they cautioned that hot biopsy forceps may increase risks of complications and produce inadequate tissue samples for histopathology.

For nonpedunculated lesions between 10 and 19 mm, guidance is minimal. The panelists recommended cold or hot snare polypectomy, although this statement was conditional and based on low-quality evidence.

Recommendations were more extensive for large nonpedunculated lesions (at least 20 mm). For such lesions, the panelists strongly recommended endoscopic mucosal resection (EMR). They emphasized that large lesions should be removed in the fewest possible pieces by an appropriately experienced endoscopist during a single colonoscopy session. The panelists recommended the use of a viscous injection solution with a contrast agent and adjuvant thermal ablation of the post-EMR margin. They recommended against the use of tattoo as a submucosal injection solution, and ablation of residual lesion tissue that is endoscopically visible. Additional recommendations for large lesions, including prophylactic closure of resection defects and coagulation techniques, were based on low-quality evidence.

For pedunculated lesions greater than 10 mm, the panelists recommended hot snare polypectomy. For pedunculated lesions with a head greater than 20 mm or a stalk thickness greater than 5 mm, they recommended prophylactic mechanical ligation.

Beyond lesion assessment and removal, recommendations addressed lesion marking, equipment, surveillance, and quality of polypectomy.

Concerning quality, the panelists recommended that endoscopists participate in a quality assurance program that documents adverse events, and that institutions use standardized polypectomy competency assessments, such as Cold Snare Polypectomy Competency Assessment Tool and/or Direct Observation of Polypectomy Skills.

AUSTIN, TEX. – Enhanced recovery after surgery (ERAS) protocols have been around for decades, but typically excluded patients having surgery for inflammatory bowel disease (IBD). However, recent studies have shown strategies to optimize these patients, including presurgery carbohydrate loading and early postsurgery feeding, can improve outcomes, according to a review of evidence presented at the annual congress of the Crohn’s & Colitis Foundation and the American Gastroenterological Association.

“It’s really important that we implement strategies to help mitigate the impact that malnutrition is going to have on our perioperative patients, and one of the ways we do that is by using an ERAS or enhanced recovery after surgery protocol,” said Kelly Issokson, MS, RD, of Cedars-Sinai Medical Center, Los Angeles. She noted that patients with IBD are five times more likely to be malnourished than non-IBD patients, and those with fistulizing Crohn’s disease and bowel resections are at greatest risk (Inflamm Bowel Dis. 2008;14:1139-46).

“I constantly see patients who are kept NPO [nothing by mouth] 12 or 24 hours before surgery, maybe even longer sometimes, unfortunately,” she said. “We should really be minimizing that NPO to help mitigate the catabolic effect that surgery has on our patients and help them recover more quickly.”

To screen surgery patients for nutrition risk, Ms. Issokson said that gastroenterologists can ask two questions from the malnutrition screening tool: Did the patient have recent unintentional weight loss, and is the patient eating less because of poor appetite? A yes to either question merits referral to a registered dietician. Malnutrition, weight loss of 5%-10% of total body weight, and sarcopenia are predictors of surgical complications for IBD patients, the latter an independent predictor in patients aged 40 years and older.

The ERAS protocol involves optimizing preoperative and postoperative nutrition, she said. It has been linked with improved outcomes in elective colorectal surgery (World J Surg. 2014;38:1531-41), although the evidence in IBD isn’t as robust. She cited a retrospective study reported at the 2019 annual Digestive Disease Week of patients with Crohn’s disease that found no difference in readmissions, complications, or reoperations between ERAS and standard-care patients.

Preoperative nutrition optimization in ERAS involves anemia and fluid management, oral nutrition supplementation, and – based on European Society for Clinical Nutrition and Metabolism (ESPEN) 2017 guidelines – delaying the operation where possible if the patient is malnourished. “Patients who receive preoperative nutrition support have been shown to have better outcomes postoperatively,” Ms. Issokson said, citing a meta-analysis of 1,111 Crohn’s disease patients that reported the complication rate was 20% in patients on nutrition support versus 60% for those on standard care; in those on enteral nutrition, the disparity was more pronounced: 21% versus 73% (Eur J Gastro Hep. 2018;30:997-1002).

Gastroenterologists should not be afraid of implementing total parenteral nutrition (TPN) perioperatively in these patients, Ms. Issokson said. “This can really help to improve outcomes and quality of life in our patients, and it’s something that we really should not shy away from,” she added in an interview. “If our patients are malnourished and meet the criteria for TPN, then we should really not be withholding it.” Patients with severe IBD who are not absorbing from their gut and can’t meet 60% of their needs by mouth are prime candidates for TPN, she said, referencing a 2019 study that reported that preoperative TPN in malnourished IBD patients resulted in a rate of overall noninfectious complications half that of no-TPN patients: 8.3% versus 16.8% (Gastroenterol Rep. 2019 Apr;7:107-14).

Carbohydrate loading before surgery is a big part of ERAS in these patients. “Surgery has a huge impact on the catabolic state of a patient,” Ms. Issokson said. “It’s similar to running a marathon; you wouldn’t go out and run a marathon without fueling up the night before with a whole bunch of carbohydrates. So we use this same strategy in our surgical patients.”

ERAS society guidelines call for 100 g of carbohydrates the night before and 50 g 2 hours before surgery in the form of a clear liquid beverage, along with permitting a light meal up to 6 hours before, with exceptions in gastroparesis, motility disorders, and emergency surgery.

Another key component of ERAS in IBD is early postoperative feeding. “Postoperatively we want to feed our patients as soon as possible,” Ms. Issokson said. ESPEN guidelines call for feeding patients with new nondiverted colorectal anastomosis within 4 hours. “Studies show that patients aren’t able to eat enough calories to help them recover postoperatively, so implementing an oral nutrition supplement might be helpful there,” she added.

AUSTIN, TEX. – Patients with inflammatory bowel disease (IBD) who want to have children can benefit from better education about recent findings that disease control, laparoscopic surgery, and in vitro fertilization (IVF) have improved their chances of conceiving, according to a review of published reports presented here at the Crohn’s & Colitis Congress, a partnership of the Crohn’s & Colitis Congress Foundation and the American Gastroenterological Association.

Richard Mark Kirkner/MDedge News

“Decreased fertility in IBD is due to voluntary childlessness, which we can change with education; surgery for IBD, which we can improve with laparoscopic surgery; and increased disease activity, which we can also make a difference in,” Sonia Friedman, MD, of Harvard Medical School, Boston, said in an interview.

Dr. Friedman and coauthors last year published an analysis of the Danish National Birth Cohort, which showed women with IBD had an 28% greater relative risk of taking a year or more to get pregnant than controls without IBD, and that the relative risk was even higher in women with Crohn’s disease — 54% (Clin Gastroenterol Hepatol. 2019. doi: 10.1016/j.cgh.2019.08.031). “We found that women with Crohn’s surgery had decreased fertility by 2.54 times greater relative risk,” she said.

“Fertility, pregnancy is the most important thing to patients,” Dr. Friedman said in an interview. “That’s what people ask me about the most. In the population of IBD patients, the onset is age 15-35, and these people are in the prime of their reproductive years.” Sexual function, known to be decreased in men and women with IBD, is also an overriding concern in these patients, she said. “There needs to be a lot more information out there about it.”

She said gastroenterologists should keep in mind that much of the evidence documenting reduced fertility after ileo-pouch anal anastomosis is dated and focused on open surgery, which caused profound scarring of the pelvis and fallopian tubes, thus hindering conception. Laparoscopic ileoanal J-pouch surgery (IPAA) has yielded much improved outcomes in women of child-bearing age, she said, citing a study late last year that reported women who had laparoscopic IPAA had a median time to pregnancy of 3.5 months versus 9 months for women who had open IPAA (Surgery. 2019;166:670-7).

“It’s really important to discuss the issues of fertility, especially for patients contemplating surgery,” Dr. Friedman said. “Emphasize that there are good outcomes with laparoscopic surgery, and they can have assisted reproductive technology [ART], or in vitro fertilization, if needed. Never withhold surgery based on fear of infertility.”

Her practice is to refer women with IBD in remission for IVF if they’ve tried to get pregnant every month for a year or more and to refer women with IBD surgery for IVF after trying to get pregnant for 6 months. Dr. Friedman coauthored two studies of the Danish National Birth Cohort of ART in women with Crohn’s disease and ulcerative colitis (UC) along with controls (Gut. 2016;65:767-76; Gut. 2017;66:556-58). “We found that women with Crohn’s and UC had a decreased chance of having a clinical pregnancy, but they had no problem carrying the pregnancy to term,” she said.

Those findings raised questions about the etiology of decreased fertility in IBD patients, which could include factors such as IVF technique, reproductive hormone and microbiome changes, or IBD medications. “How can we carry that forward to all women with IBD?” she said. Women with IBD have less chance of conceiving with each IVF treatment cycle than do women without IBD, she said. “The most interesting thing is that the reduced chance of live birth after IVF treatment in Crohn’s and UC is related to the stages of implantation and not to the ability to maintain the fetus throughout pregnancy,” she said.

Dr. Friedman has no financial relationships to disclose.

“Fertility, pregnancy is the most important thing to patients,” Dr. Friedman said in an interview. “That’s what people ask me about the most. In the population of IBD patients, the onset is age 15-35, and these people are in the prime of their reproductive years.” Sexual function, known to be decreased in men and women with IBD, is also an overriding concern in these patients, she said. “There needs to be a lot more information out there about it.”

She said gastroenterologists should keep in mind that much of the evidence documenting reduced fertility after ileo-pouch anal anastomosis is dated and focused on open surgery, which caused profound scarring of the pelvis and fallopian tubes, thus hindering conception. Laparoscopic ileoanal J-pouch surgery (IPAA) has yielded much improved outcomes in women of child-bearing age, she said, citing a study late last year that reported women who had laparoscopic IPAA had a median time to pregnancy of 3.5 months versus 9 months for women who had open IPAA (Surgery. 2019;166:670-7).

“It’s really important to discuss the issues of fertility, especially for patients contemplating surgery,” Dr. Friedman said. “Emphasize that there are good outcomes with laparoscopic surgery, and they can have assisted reproductive technology [ART], or in vitro fertilization, if needed. Never withhold surgery based on fear of infertility.”

Her practice is to refer women with IBD in remission for IVF if they’ve tried to get pregnant every month for a year or more and to refer women with IBD surgery for IVF after trying to get pregnant for 6 months. Dr. Friedman coauthored two studies of the Danish National Birth Cohort of ART in women with Crohn’s disease and ulcerative colitis (UC) along with controls (Gut. 2016;65:767-76; Gut. 2017;66:556-58). “We found that women with Crohn’s and UC had a decreased chance of having a clinical pregnancy, but they had no problem carrying the pregnancy to term,” she said.

Those findings raised questions about the etiology of decreased fertility in IBD patients, which could include factors such as IVF technique, reproductive hormone and microbiome changes, or IBD medications. “How can we carry that forward to all women with IBD?” she said. Women with IBD have less chance of conceiving with each IVF treatment cycle than do women without IBD, she said. “The most interesting thing is that the reduced chance of live birth after IVF treatment in Crohn’s and UC is related to the stages of implantation and not to the ability to maintain the fetus throughout pregnancy,” she said.

Dr. Friedman has no financial relationships to disclose.

BALTIMORE – About one in 4,000 children are born with hemimegalencephaly, meaning one brain hemisphere is abnormally formed and larger than the other.

The abnormal hemisphere causes seizures, and when they become intractable, the standard of care is to remove it as soon as possible; the longer the abnormal hemisphere is left in, the worse children do developmentally, and the less likely hemispherectomy will stop the seizures.

A problem comes up, however, when children become intractable before they’re 3 months old: “Neurosurgeons won’t touch them,” said Taeun Chang, MD, a neonatal neurointensivist at Children’s National Medical Center in Washington.

Newborns’ coagulation systems aren’t fully developed, and the risk of fatal hemorrhage is too high, she explained.

Out of what she said was a sense of “desperation” to address the situation, Dr. Chang has spearheaded a new approach for newborns at Children’s National, serial glue embolization to induce targeted strokes in the affected hemisphere. She reported on the first five cases at the American Epilepsy Society annual meeting.

At this point, “I feel like we’ve pretty much figured out the technique in terms of minimizing the complications. There’s no reason to wait anymore” for surgery as newborns get worse and worse, she said.

The technique

In two or three stages over several days, the major branches of the affected hemisphere’s anterior, middle, and posterior cerebral arteries are embolized. “You have to glue a long area and put in a lot of glue and glue up the secondary branches because [newborns] are so good at forming collaterals,” Dr. Chang said.

Fresh frozen plasma is given before and after each embolization session to boost coagulation proteins. Nicardipine is given during the procedure to prevent vasospasms. The one death in the series, case four, was in an 11-day old girl who vasospasmed, ruptured an artery over the tip of the guidewire, and hemorrhaged.

After the procedure, body temperature is kept at 36° C to prevent fever; sodium is kept high, and ins and outs are matched, to reduce brain edema; and blood pressure is tightly controlled. Children are kept on EEG during embolization and for days afterwards, and seizures, if any, are treated. The next embolization comes after peak swelling has passed in about 48-72 hours.

“The reason we can get away with this without herniation is that newborns’ skulls are soft, and their sutures are open,” so cerebral edema is manageable, Dr. Chang said.

Learning curve and outcomes

“What we learned in the first two cases” – a 23-day-old boy and 49-day-old girl – “was to create effective strokes. That’s not something any of us are taught to do,” she said.

“We were not trying to destroy the whole hemisphere, just the area that was seizing on EEG.” That was a mistake, she said: Adjacent areas began seizing and both children went on to anatomical hemispherectomies and needed shunts.

They are 5 years old now, and both on four seizure medications. The boy is in a wheelchair, fed by a G-tube, and has fewer than 20 words. The girl has a gait trainer, is fed mostly by G-tube, and has more than 50 words.

The third patient had her middle and posterior cerebral arteries embolized beginning when she was 43 days old. She was seizure free when she left the NICU, but eventually had a functional hemispherectomy. She’s 2 years old now, eating by mouth, in a gait trainer, and speaks in one- or two-word sentences. She’s on three seizure medications.

Outcomes have been best for patient five. Her posterior, middle, and anterior cerebral arteries were embolized starting at 14 days. She’s 1 year old now, seizure free on three medications, eating by G-tube and mouth, and has three-five words.

Dr. Chang said that newborns with hemimegalencephaly at Children’s National aren’t lingering as long on failing drug regimens these days. “We go to intervention now that we have this option” after they fail just two or three medications.

Given that the fifth patient, treated at 2 weeks old, is the only one who has been seizure free, she suspects it’s probably best to do embolization sooner rather than later, just as with anatomical hemispherectomy in older children. “We’ve got the sense that even a couple of weeks makes a difference. People need to come to us sooner,” Dr. Chang said.

It’s possible embolization could be a sound alternative to surgery even after 3 months of age. Focal embolization might also be a viable alternative to surgery to knock out epileptogenic lesions in children with tuberous sclerosis. Dr. Chang and her colleagues are interested in those and other possibilities, and plan to continue to develop the approach, she said.

There was no funding, and the investigators didn’t have any relevant disclosures.

BALTIMORE – In the absence of MRI evidence of mesial temporal sclerosis (MTS), sparing the hippocampus during anterior temporal lobectomy for refractory epilepsy reduces memory loss without affecting the procedure’s efficacy, according to a review from researchers at Thomas Jefferson University in Philadelphia.

Often, the hippocampus and other mesial structures are removed even if they appear normal. The concern is that even normal looking tissue could harbor epileptogenic elements and leaving them in tact could reduce postoperative seizure control, explained senior investigator and neurologist Michael Sperling, MD, director of the Jefferson Comprehensive Epilepsy Center.

He and his colleagues wanted to see if that was really true, so they compared outcomes in 21 patients who had mesial-sparing lobectomies with 19 patients who had the standard approach. Cases and controls were matched for age, preoperative seizure frequency, side of surgery, and other factors. None of the patients had MTS.

There was no significant difference in postoperative seizure recurrence between the two groups (P = .974). The standard procedure had a slight edge early on, but at 2.5 years, just over 60% of patients in both groups were seizure free. At 5 years, about 50% were seizure free, and almost 40% in both arms at 7.5 years.

About two-thirds of patients in each arm had pre- and postoperative verbal memory testing, with similar duration from surgery to postop evaluation. There was no change among the hippocampus-sparing patients, but a roughly one standard deviation drop in delayed recall and logical memory on the California Verbal Learning Test in the standard group.

Even so, it wasn’t enough to affect employment, which the investigators used as a surrogate for disability; postoperative employment was comparable in both groups. People mostly retained their jobs, and there was no difference in job loss. A few people in each arm actually found jobs after surgery.

The investigators concluded that “it is reasonable to recommend mesial temporal sparing procedure in patients with dominant neocortical temporal lobe epilepsy when the hippocampus appears normal in the MRI. However, as resecting the mesial temporal structures was not associated with a greater chance of becoming unemployed following the surgery, there appears to be no major contraindication to performing an [anterior temporal lobectomy] if clinically warranted.”

The results are reassuring. “My bias walking in was that” seizure recurrence would be worse after hippocampal-sparing surgery. “I was pleased to see that it was about the same. If you want to try to preserve verbal memory and the MRI is normal, you can get away with sparing the mesial temporal structures, and still get a good seizure outcome,” Dr. Sperling said at the annual meeting of the American Epilepsy Society, where the study was presented.

“But if you have to take the hippocampus for whatever reason, the functional consequence of a decline in verbal memory is not severe enough as to be disabling,” which is “one of the big concerns” with temporal lobectomy, he said.

The findings “will make us more likely to recommend mesial-sparing surgery, but at the same time” perhaps not be quite as worried about disability with the standard approach.

Temporal lobe epilepsy with normal mesial structures isn’t very common, which explains the small numbers in the series. It’s possible subtle difference in seizure control and employment outcomes would have been found with a larger series, “but obviously there were no major differences. I think the fundamental questions have been answered to my satisfaction,” Dr. Sperling said.

Overall, “it’s better to operate and try to cure people than to worry that you will make their memory worse when the consequences of having uncontrolled epilepsy is a higher death rate,” he said.

There were about equal numbers of men and women in the review; patients were in their early 30s, on average; and most had left-sided surgery. Just over half in each arm had preoperative tonic-clonic seizures. The mean duration of epilepsy was 14.9 years in the mesial-sparing group, and 8.6 years in the standard arm.

There was no funding for the review, and Dr. Sperling didn’t have any relevant disclosures.
