Early-onset Colorectal Cancer Patients Do Not Require Shorter Intervals for Post-surgical Surveillance Colonoscopy.

BACKGROUND & AIMS: Early-onset colorectal cancer (EO-CRC), diagnosed before age 50, is rising in incidence worldwide. Although post-surgical colonoscopy surveillance strategies exist, appropriate intervals in EO-CRC remain elusive, as long-term surveillance outcomes remain scant. We sought to compare findings of surveillance colonoscopies of EO-CRC with patients with average onset colorectal cancer (AO-CRC) to help define surveillance outcomes in these groups. METHODS: Single-institution retrospective chart review identified EO-CRC and AO-CRC patients with colonoscopy and no evidence of disease. Surveillance intervals and time to development of advanced neoplasia (CRC and advanced polyps [adenoma/sessile serrated]) were examined. For each group, 3 serial surveillance colonoscopies were evaluated. Statistical analyses were performed utilizing log-ranked Kaplan-Meier method and Cox proportional hazards. RESULTS: A total of 1259 patients with CRC were identified, with 612 and 647 patients in the EO-CRC and AO-CRC groups, respectively. Compared with patients with AO-CRC, patients with EO-CRC had a 29% decreased risk of developing advanced neoplasia from time of initial surgery to first surveillance colonoscopy (hazard ratio, 0.71; 95% confidence interval, 0.52-1.0). Average follow-up time from surgical resection to first surveillance colonoscopy was 12.6 months for both cohorts. Overall surveillance findings differed between cohorts (P = .003), and patients with EO-CRC were found to have less advanced neoplasia compared with their counterparts with AO-CRC (12.4% vs 16.0%, respectively). Subsequent colonoscopies found that, while patients with EO-CRC returned for follow-up surveillance colonoscopy earlier than patients with AO-CRC, the EO-CRC cohort did not have more advanced neoplasia nor non-advanced adenomas. CONCLUSIONS: Patients with EO-CRC do not have an increased risk of advanced neoplasia compared with patients with AO-CRC and therefore do not require more frequent colonoscopy surveillance than current guidelines recommend.

The Role of Screening and Early Detection in Upper Gastrointestinal Cancers.

Upper gastrointestinal cancers are among the leading causes of cancer deaths worldwide with exceptionally poor prognosis, which is largely attributable to frequently delayed diagnosis. Although effective screening is critical for early detection, the highly variable incidence of upper gastrointestinal cancers presents challenges, rendering universal screening programs suboptimal in most populations globally. Optimal strategies in regions of modest incidence, such as the United States, require a targeted approach, focused on high-risk individuals based on demographic, familial, and clinicopathologic risk factors. Assessment of underlying precancerous lesions has key implications for risk stratification and informing clinical decisions to improve patient outcomes.

Immune-Related Colitis Is Associated with Fecal Microbial Dysbiosis and Can Be Mitigated by Fecal Microbiota Transplantation.

Colitis induced by treatment with immune-checkpoint inhibitors (ICI), termed irColitis, is a substantial cause of morbidity complicating cancer treatment. We hypothesized that abnormal fecal microbiome features would be present at the time of irColitis onset and that restoring the microbiome with fecal transplant from a healthy donor would mitigate disease severity. Herein, we present fecal microbiota profiles from 18 patients with irColitis from a single center, 5 of whom were treated with healthy-donor fecal microbial transplantation (FMT). Although fecal samples collected at onset of irColitis had comparable α-diversity to that of comparator groups with gastrointestinal symptoms, irColitis was characterized by fecal microbial dysbiosis. Abundances of Proteobacteria were associated with irColitis in multivariable analyses. Five patients with irColitis refractory to steroids and biologic anti-inflammatory agents received healthy-donor FMT, with initial clinical improvement in irColitis symptoms observed in four of five patients. Two subsequently exhibited recurrence of irColitis symptoms following courses of antibiotics. Both received a second "salvage" FMT that was, again, followed by clinical improvement of irColitis. In summary, we observed distinct microbial community changes that were present at the time of irColitis onset. FMT was followed by clinical improvements in several cases of steroid- and biologic-agent-refractory irColitis. Strategies to restore or prevent microbiome dysbiosis in the context of immunotherapy toxicities should be further explored in prospective clinical trials.

Prolonged Gastrointestinal Manifestations After Recovery From COVID-19.

BACKGROUND & AIMS: Acute enteric infections are well known to result in long-term gastrointestinal (GI) disorders. Although COVID-19 is principally a respiratory illness, it demonstrates significant GI tropism, possibly predisposing to prolonged gut manifestations. We aimed to examine the long-term GI impact of hospitalization with COVID-19. METHODS: Nested within a large-scale observational cohort study of patients hospitalized with COVID-19 across North America, we performed a follow-up survey of 530 survivors 12-18 months later to assess for persistent GI symptoms and their severity, and for the development of disorders of gut-brain interaction (DGBIs). Eligible patients were identified at the study site level and surveyed electronically. The survey instrument included the Rome IV Diagnostic Questionnaire for DGBI, a rating scale of 24 COVID-related symptoms, the Gastrointestinal Symptoms Rating Scale, and the Impact of Events-Revised trauma symptom questionnaire (a measure of posttraumatic stress associated with the illness experience). A regression analysis was performed to explore the factors associated with GI symptom severity at follow-up. RESULTS: Of the 530 invited patients, 116 responded (52.6% females; mean age, 55.2 years), and 73 of those (60.3%) met criteria for 1 or more Rome IV DGBI at follow-up, higher than the prevalence in the US general population (P < .0001). Among patients who experienced COVID-related GI symptoms during the index hospitalization (abdominal pain, nausea, vomiting, or diarrhea), 42.1% retained at least 1 of these symptoms at follow-up; in comparison, 89.8% of respondents retained any (GI or non-GI) COVID-related symptom. The number of moderate or severe GI symptoms experienced during the initial COVID-19 illness by self-report correlated with the development of DGBI and severity of GI symptoms at follow-up. Posttraumatic stress disorder (Impact of Events-Revised score ≥33) related to the COVID-19 illness experience was identified in 41.4% of respondents and those individuals had higher DGBI prevalence and GI symptom severity. Regression analysis revealed that higher psychological trauma score (Impact of Events-Revised) was the strongest predictor of GI symptom severity at follow-up. CONCLUSIONS: In this follow-up survey of patients 12-18 months after hospitalization with COVID-19, there was a high prevalence of DGBIs and persistent GI symptoms. Prolonged GI manifestations were associated with the severity of GI symptoms during hospitalization and with the degree of psychological trauma related to the illness experience.

Prevalence and Clinical Implications of Mismatch Repair-Proficient Colorectal Cancer in Patients With Lynch Syndrome.

PURPOSE: Lynch syndrome (LS)-associated colorectal cancer (CRC) is characterized by mismatch repair-deficiency (MMR-D) and/or microsatellite instability (MSI). However, with increasing utilization of germline testing, MMR-proficient (MMR-P) and/or microsatellite stable (MSS) CRC has also been observed. We sought to characterize MMR-P/MSS CRC among patients with LS. METHODS: Patients with solid tumors with germline MMR pathogenic/likely pathogenic (P/LP) variants were identified on a prospective matched tumor-normal next-generation sequencing (NGS) protocol. CRCs were evaluated for MMR-D via immunohistochemical (IHC) staining and/or MSI via NGS. Clinical variables were correlated with MMR status using nonparametric tests. RESULTS: Among 17,617 patients with solid tumors, 1.4% (n = 242) had LS. A total of 36% (86 of 242) of patients with LS had at least one CRC that underwent NGS profiling, amounting to 99 pooled CRCs assessed. A total of 10% (10 of 99) of CRCs were MMR-P, with 100% concordance between MSS status and retained MMR protein staining. A total of 89% (8 of 9) of patients in the MMR-P group had MSH6 or PMS2 variants, compared with 30% (23 of 77) in the MMR-D group (P = .001). A total of 46% (6 of 13) of PMS2+ patients had MMR-P CRC. The median age of onset was 58 and 43 years for MMR-P and MMR-D CRC, respectively (P = .07). Despite the later median age of onset, 40% (4 of 10) of MMR-P CRCs were diagnosed <50. A total of 60% (6 of 10) of MMR-P CRCs were metastatic compared with 13% (12 of 89) of MMR-D CRCs (P = .002). A total of 33% (3 of 9) of patients with MMR-P CRC did not meet LS testing criteria. CONCLUSION: Patients with LS remained at risk for MMR-P CRC, which was more prevalent among patients with MSH6 and PMS2 variants. MMR-P CRC was later onset and more commonly metastatic compared with MMR-D CRC. Confirmation of tumor MMR/MSI status is critical for patient management and familial risk estimation.

Randomized Trial of Facilitated Adherence to Screening Colonoscopy vs Sequential Fecal-Based Blood Test.

BACKGROUND & AIMS: Colorectal cancer (CRC) screening guidelines include screening colonoscopy and sequential high-sensitivity fecal occult blood testing (HSgFOBT), with expectation of similar effectiveness based on the assumption of similar high adherence. However, adherence to screening colonoscopy compared with sequential HSgFOBT has not been reported. In this randomized clinical trial, we assessed adherence and pathology findings for a single screening colonoscopy vs sequential and nonsequential HSgFOBTs. METHODS: Participants aged 40-69 years were enrolled at 3 centers representing different clinical settings. Participants were randomized into a single screening colonoscopy arm vs sequential HSgFOBT arm composed of 4-7 rounds. Initial adherence to screening colonoscopy and sequential adherence to HSgFOBT, follow-up colonoscopy for positive HSgFOBT tests, crossover to colonoscopy, and detection of advanced neoplasia or large serrated lesions (ADN-SERs) were measured. RESULTS: There were 3523 participants included in the trial; 1761 and 1762 participants were randomized to the screening colonoscopy and HSgFOBT arms, respectively. Adherence was 1473 (83.6%) for the screening colonoscopy arm vs 1288 (73.1%) for the HSgFOBT arm after 1 round (relative risk [RR], 1.14; 95% CI, 1.10-1.19; P ≤ .001), but only 674 (38.3%) over 4 sequential HSgFOBT rounds (RR, 2.19; 95% CI, 2.05-2.33). Overall adherence to any screening increased to 1558 (88.5%) in the screening colonoscopy arm during the entire study period and 1493 (84.7%) in the HSgFOBT arm (RR, 1.04; 95% CI, 1.02-1.07). Four hundred thirty-six participants (24.7%) crossed over to screening colonoscopy during the first 4 rounds. ADN-SERs were detected in 121 of the 1473 participants (8.2%) in the colonoscopy arm who were adherent to protocol in the first 12 months of the study, whereas detection of ADN-SERs among those who were not sequentially adherent (n = 709) to HSgFOBT was subpar (0.6%) (RR, 14.72; 95% CI, 5.46-39.67) compared with those who were sequentially adherent (3.3%) (n = 647) (RR, 2.52; 95% CI, 1.61-3.98) to HSgFOBT in the first 4 rounds. When including colonoscopies from HSgFOBT patients who were never positive yet crossed over (n = 1483), 5.5% of ADN-SERs were detected (RR, 1.50; 95% CI, 1.15-1.96) in the first 4 rounds. CONCLUSIONS: Observed adherence to sequential rounds of HSgFOBT was suboptimal compared with a single screening colonoscopy. Detection of ADN-SERs was inferior when nonsequential HSgFOBT adherence was compared with sequential adherence. However, the greatest number of ADN-SERs was detected among those who crossed over to colonoscopy and opted to receive a colonoscopy. The effectiveness of an HSgFOBT screening program may be enhanced if crossover to screening colonoscopy is permitted. CLINICALTRIALS: gov, Number: NCT00102011.

Clinical features of young onset colorectal cancer patients from a large cohort at a single cancer center.

PURPOSE: The aim of this study is to describe the demographics and clinical features of patients with young onset (YO) CRC. METHODS: A retrospective review of patients with CRC diagnosed between ages 20 and 49 years was evaluated at the Memorial Sloan Kettering Cancer Center from 1/2004 to 6/2019. We excluded those with a hereditary CRC syndrome, inflammatory bowel disease, or prior CRC diagnosis. Patient demographics; presenting symptoms; medical, surgical, and smoking history; family history of cancer; tumor characteristics; and pathology were obtained from the electronic medical record. RESULTS: We identified 3856 YO CRC patients (median age CRC diagnosis 43; 52.5% male). A total of 59.1% were overweight or obese (32.2% and 26.9%, respectively). Most (90.1%) had no family history of CRC in a first-degree relative; 56.3% of patients reported being never smokers; 5.2% had diabetes. The most common presenting symptoms were rectal bleeding (47.7%), abdominal pain/bloating (33.1%), and change in bowel habits (24.7%). The majority presented with left-sided cancers (77.3%), at late-stage disease (68.4% at stages 3 or 4). CONCLUSION: Most YO CRC patients presented with rectal bleeding or abdominal pain, left-sided cancers, and later-stage disease and had no family history of CRC in a first-degree relative. Over half were overweight and obese and were more likely to have never smoked. More data are needed to better understand YO CRC risk factors and to help identify high-risk populations who may benefit from earlier screening.

Brief Report: Chylothorax and Chylous Ascites During RET Tyrosine Kinase Inhibitor Therapy.

INTRODUCTION: Spontaneous chylous effusions are rare; however, they have been observed by independent investigators in patients treated with RET tyrosine kinase inhibitors (TKIs). METHODS: This multicenter, retrospective study evaluated the frequency of chylous effusions in patients treated with RET TKIs. Clinicopathologic features and management of patients with chylous effusions were evaluated. RESULTS: A pan-cancer cohort of 7517 patients treated with one or more multikinase inhibitor or selective RET TKI and a selective TKI cohort of 96 patients treated with selpercatinib or pralsetinib were analyzed. Chylous effusions were most common with selpercatinib (7%), followed by agerafenib (4%), cabozantinib (0.3%), and lenvatinib (0.02%); none were observed with pralsetinib. Overall, 12 patients had chylothorax, five had chylous ascites, and five had both. Time from TKI initiation to diagnosis ranged from 0.5 to 50 months. Median fluid triglyceride level was lower in chylothoraces than in chylous ascites (397 mg/dL [interquartile range: 304-4000] versus 3786 mg/dL [interquartile range: 842-6596], p = 0.035). Malignant cells were present in 13% (3 of 22) of effusions. Chyle leak was not identified by lymphangiography. After initial drainage, 76% of patients with chylothorax and 80% with chylous ascites required additional interventions. Selpercatinib dose reduction and discontinuation rates in those with chylous effusions were 47% and 0%, respectively. Median time from diagnosis to disease progression was not reached (95% confidence interval: 14.5-undefined); median time from diagnosis to TKI discontinuation was 11.4 months (95% confidence interval: 8.2-14.9). CONCLUSIONS: Chylous effusions can emerge during treatment with selected RET TKIs. Recognition of this side effect is key to prevent potential misattribution of worsening effusions to progressive malignancy.

Endoscopic stenting for malignant biliary obstruction is technically successful in patients with preexisting duodenal stents.

Background and study aims There are limited data on the success of endoscopic retrograde cholangiopancreatography (ERCP) in patients with malignant biliary and duodenal obstruction with a preexisting duodenal stent. The aim of this study was to evaluate patient and procedural outcomes of a cohort of patients with preexisting duodenal stents who underwent an attempt at ERCP for malignant biliary obstruction (MBO). Patients and methods This was a single-center retrospective study on consecutive patients with a preexisting duodenal stent who underwent attempted ERCP for MBO. Technical success was defined as successful cannulation of the common bile duct, with successful dilation and/or deployment of a biliary stent under fluoroscopy. Clinical success was defined as number of patients in the entire group who underwent ERCP successfully with resolution of symptoms. Results We identified 64 patients (73 % men, 74 % white, median age 62 years) with a preexisting duodenal stent who underwent 85 attempts at ERCP. ERCP was technically successful in 50 of 85 procedures (59 %). Overall ERCP was successful in 41 of 85 patients (48 %). ERCP was more likely to be successful in patients with Type 1 and 3 duodenal strictures than with Type 2 strictures (83 % and 92 % vs. 42 %, P  < 0.01), in patients with a preexisting sphincterotomy (79% vs. 20 %, P  = 0.01) or preexisting biliary stent (66 % vs. 34 %, P  = 0.04). Adverse events included bleeding (n = 3), post-procedure fever (n = 3) and abdominal pain (n = 1). Conclusions Although biliary stenting via ERCP is often technically challenging in patients with a prior duodenal stent, it is a safe and effective method of biliary drainage. ERCP should be attempted in patients with Type 1 and 3 duodenal strictures, a prior sphincterotomy or an indwelling biliary stent.

Effectiveness of a surveillance program of upper endoscopy for upper gastrointestinal cancers in Lynch syndrome patients.

BACKGROUND AND AIMS: Lynch syndrome (LS) is the most common cause of hereditary colorectal cancer and is associated with an increased lifetime risk of gastric and duodenal cancers of 8-16% and 7%, respectively; therefore, we aim to describe an esophagogastroduodenoscopy (EGD) surveillance program for upper gastrointestinal (GI) precursor lesions and cancer in LS patients. METHODS: Patients who either had positive genetic testing or met clinical criteria for LS who had a surveillance EGD at our institution from 1996 to 2017 were identified. Patients were included if they had at least two EGDs or an upper GI cancer detected on the first surveillance EGD. EGD and pathology reports were extracted manually. RESULTS: Our cohort included 247 patients with a mean age of 47.1 years (SD 12.6) at first EGD. Patients had a mean of 3.5 EGDs (range 1-16). Mean duration of follow-up was 5.7 years. Average interval between EGDs was 2.3 years. Surveillance EGD detected precursor lesions in 8 (3.2%) patients, two (0.8%) gastric cancers and two (0.8%) duodenal cancers. Two interval cancers were diagnosed: a duodenal adenocarcinoma was detected 2 years, 8 months after prior EGD and a jejunal adenocarcinoma was detected 1 year, 9 months after prior EGD. CONCLUSIONS: Our data suggest that surveillance EGD is a useful tool to help detect precancerous and cancerous upper GI lesions in LS patients. To our knowledge, this is the first study to examine a program of surveillance EGDs in LS patients. More data are needed to determine the appropriate surveillance interval.

Fecal Microbiota Transplantation Is Safe for Clostridiodies difficile Infection in Patients with Solid Tumors Undergoing Chemotherapy.

BACKGROUND: Recurrent Clostridiodies difficile infection (CDI) contributes to morbidity and mortality in cancer patients. Fecal microbiota transplantation (FMT) has been proven to be effective in treatment of recurrent CDI, but immunocompromised patients have been excluded from prospective studies due to safety concerns. The aim of this study was to investigate the safety of FMT for recurrent CDI in immunocompromised patients with solid tumor malignancy undergoing chemotherapy. METHODS: This was a single center, prospective observational study of patients at a tertiary care cancer center of 10 patients with recurrent CDI who were at least 18 years of age, with a solid tumor malignancy who had received chemotherapy within the previous 6 months. Patients received FMT either by upper endoscopy or colonoscopy and were followed for 6 months. Safety was a primary outcome measured by infections occurring within 2 weeks of FMT. Efficacy of FMT was also evaluated. RESULTS: Nineteen patients were evaluated. On applying exclusion criteria, 10 were included in the study. One patient requested to be off study within 2 weeks and was considered a treatment failure. Seven received FMT via upper endoscopy, three via colonoscopy. There were no infectious complications from FMT. Eight patients (80%) were cured after the first FMT. All eight patients went on to restart oncologic treatment with an average of 32.5 days after FMT. CONCLUSIONS: FMT is safe and effective for recurrent CDI in solid tumor patients undergoing chemotherapy. Patients can resume oncologic treatment after FMT.

Impact of COVID-19 on Endoscopy Training: Perspectives from a Global Survey of Program Directors and Endoscopy Trainers.

BACKGROUND/AIMS: The coronavirus disease of 2019 (COVID-19) pandemic has impacted the training of medical trainees internationally. The aim of this study was to assess the global impact of COVID-19 on endoscopy training from the perspective of endoscopy trainers and to identify strategies implemented to mitigate the impact on trainee education. METHODS: Teaching faculty of gastroenterology (GI) training programs globally were invited to complete a 36-question web-based survey to report the characteristics of their training programs and the impact of COVID-19 on various aspects of endoscopy training, including what factors decisions were based on. RESULTS: The survey response rate was 52.6% (305 out of 580 individuals); 92.8% reported a negative impact on endoscopy training, with suspension of elective procedures (77.1%) being the most detrimental factor. Geographic variations were noted, with European programs reporting the lowest percentage of trainee participation in procedures. A higher proportion of trainees in the Americas were allowed to continue performing procedures, and trainers from the Americas reported receiving the greatest support for endoscopy teaching. CONCLUSION: This study demonstrated that the COVID-19 pandemic has had a significant negative impact on GI endoscopy training internationally, as reported by endoscopy trainers. Focus-optimizing endoscopy training and assessment of competencies are necessary to ensure adequate endoscopy training.

Feasibility of Patient Navigation and Impact on Adherence to Screening Colonoscopy in a Large Diverse Urban Population.

INTRODUCTION: Disparities observed in colorectal cancer (CRC) incidence and mortality among blacks and Hispanics compared with whites may be in part due to lower screening rates. The New York City (NYC) Department of Health and Mental Hygiene (DOHMH) has implemented a patient navigator (PN) program at NYC hospitals serving lower-income patients to promote high adherence by patients referred for screening colonoscopy. A prior study showed this PN program increased adherence at 3 public hospitals. The aim of this study was to determine the feasibility of expanding the PN program to 10 hospital sites by assessing the impact of the PN program on adherence to screening colonoscopy in a large, urban, lower-income population. METHODS: Data were collected from 2007 through the first quarter of 2012 from PN sites. One site also contributed data from the pilot phase of the project, from 2005 to 2006. Adherence to scheduled screening colonoscopy among those ≥ 50 years was assessed among 10 hospital sites in NYC participating in the colonoscopy PN program. RESULTS: Among the 37,077 asymptomatic adults ≥ 50 years who were scheduled for a screening colonoscopy from 2005 to the first quarter of 2012, 84.2% (83.2% of black, 84.9% of Hispanic, and 87.5% of white adults) were adherent to scheduled colonoscopy. CONCLUSIONS: Expansion of PN programs to navigate all patients referred for a colonoscopy was feasible in a large, urban setting. This can be implemented resulting in high overall adherence rates to screening colonoscopies. The program likely did not result in large ethnic disparities.

Digestive Manifestations in Patients Hospitalized With Coronavirus Disease 2019.

BACKGROUND & AIMS: The prevalence and significance of digestive manifestations in coronavirus disease 2019 (COVID-19) remain uncertain. We aimed to assess the prevalence, spectrum, severity, and significance of digestive manifestations in patients hospitalized with COVID-19. METHODS: Consecutive patients hospitalized with COVID-19 were identified across a geographically diverse alliance of medical centers in North America. Data pertaining to baseline characteristics, symptomatology, laboratory assessment, imaging, and endoscopic findings from the time of symptom onset until discharge or death were abstracted manually from electronic health records to characterize the prevalence, spectrum, and severity of digestive manifestations. Regression analyses were performed to evaluate the association between digestive manifestations and severe outcomes related to COVID-19. RESULTS: A total of 1992 patients across 36 centers met eligibility criteria and were included. Overall, 53% of patients experienced at least 1 gastrointestinal symptom at any time during their illness, most commonly diarrhea (34%), nausea (27%), vomiting (16%), and abdominal pain (11%). In 74% of cases, gastrointestinal symptoms were judged to be mild. In total, 35% of patients developed an abnormal alanine aminotransferase or total bilirubin level; these were increased to less than 5 times the upper limit of normal in 77% of cases. After adjusting for potential confounders, the presence of gastrointestinal symptoms at any time (odds ratio, 0.93; 95% CI, 0.76-1.15) or liver test abnormalities on admission (odds ratio, 1.31; 95% CI, 0.80-2.12) were not associated independently with mechanical ventilation or death. CONCLUSIONS: Among patients hospitalized with COVID-19, gastrointestinal symptoms and liver test abnormalities were common, but the majority were mild and their presence was not associated with a more severe clinical course.

The global impact of COVID-19 on gastrointestinal endoscopy units: An international survey of endoscopists.

BACKGROUND & STUDY AIMS: Corona virus disease-19 (COVID-19) pandemic has markedly impacted routine medical services including gastrointestinal (GI) endoscopy. We aim to report the real-life performance in high volume GI endoscopy units during the pandemic. PATIENTS AND METHODS: A web-based survey covering all aspects of daily performance in GI endoscopy units was sent to endoscopy units worldwide. Responses were collected and data were analyzed to reveal the effect of COVID-19 pandemic on endoscopy practice. RESULTS: Participants from 48 countries (n = 163) responded to the survey with response rate of 67.35%. The majority (85%) decreased procedure volume by over 50%, and four endoscopy units (2.45%) completely stopped. The top three indications for procedures included upper GI bleeding (89.6%), lower GI bleeding (65.6%) and cholangitis (62.6%). The majority (93.9%) triaged patients for COVID-19 prior to procedure. N95 masks were used in (57.1%), isolation gowns in (74.2%) and head covers in (78.5%). Most centers (65%) did not extend use of N95 masks, however 50.9% of centers reused N95 masks. Almost all (91.4%) centers used standard endoscopic decontamination and most (69%) had no negative pressure rooms. Forty-two centers (25.8%) reported positive cases of SARS-CoV-2 infection among patients and 50 (30.7%) centers reported positive cases of SARS-CoV-2 infection among their healthcare workers. CONCLUSIONS: Most GI endoscopy centers had a significant reduction in their volume and most procedures performed were urgent. Most centers used the recommended personal protective equipment (PPE) by GI societies however there is still a possibility of transmission of SARS-CoV-2 infection in GI endoscopy units.

Plans to Reactivate Gastroenterology Practices Following the COVID-19 Pandemic: A Survey of North American Centers.

BACKGROUND & AIMS: Practices dramatically reduced endoscopy services due to the COVID-19 pandemic. Because practices now are considering reintroduction of elective endoscopy, we conducted a survey of North American practices to identify reactivation barriers and strategies. METHODS: We designed and electronically distributed a web-based survey to North American gastroenterologists consisting of 7 domains: institutional demographics, impact of COVID-19 on endoscopy practice, elective endoscopy resumption plans, anesthesia modifications, personal protective equipment policies, fellowship training, and telemedicine use. Responses were stratified by practice type: ambulatory surgery center (ASC) or hospital-based. RESULTS: In total, 123 practices (55% ASC-based and 45% hospital-based) responded. At the pandemic's peak (as reported by the respondents), practices saw a 90% decrease in endoscopy volume, with most centers planning to resume elective endoscopy a median of 55 days after initial restrictions. Declining community prevalence of COVID-19, personal protective equipment availability, and preprocedure severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing availability were ranked as the 3 primary factors influencing reactivation timing. ASC-based practices were more likely to identify preprocedure testing availability as a major factor limiting elective endoscopy resumption (P = .001). Preprocedure SARS-CoV-2 testing was planned by only 49.2% of practices overall; when testing is performed and negative, 52.9% of practices will continue to use N95 masks. CONCLUSIONS: This survey highlights barriers and variable strategies for reactivation of elective endoscopy services after the COVID-19 pandemic. Our results suggest that more widespread access to preprocedure SARS-CoV-2 tests with superior performance characteristics is needed to increase provider and patient comfort in proceeding with elective endoscopy.

Donning a New Approach to the Practice of Gastroenterology: Perspectives From the COVID-19 Pandemic Epicenter.

The COVID-19 pandemic seemingly is peaking now in New York City and has triggered significant changes to the standard management of gastrointestinal diseases. Priorities such as minimizing viral transmission, preserving personal protective equipment, and freeing hospital beds have driven unconventional approaches to managing gastroenterology (GI) patients. Conversion of endoscopy units to COVID units and redeployment of GI fellows and faculty has profoundly changed the profile of most GI services. Meanwhile, consult and procedural volumes have been reduced drastically. In this review, we share our collective experiences regarding how we have changed our practice of medicine in response to the COVID surge. Although we review our management of specific consults and conditions, the overarching theme focuses primarily on noninvasive measures and maximizing medical therapies. Endoscopic procedures have been reserved for those timely interventions that are most likely to be therapeutic. The role of multidisciplinary discussion, although always important, now has become critical. The support of our faculty and trainees remains essential. Local leadership can encourage well-being by frequent team check-ins and by fostering trainee development through remote learning. Advancing a clear vision and a transparent process for how to organize and triage care in the recovery phase will allow for a smooth transition to our new normal.
