RESUMO
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.
RESUMO
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.

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.
RESUMO
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.

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.

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.

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.

INTRODUCTION: Bevacizumab is a humanized anti-vascular endothelial growth factor monoclonal antibody used in the treatment of cervical cancer, ovarian cancer, colorectal cancer, lung cancer, renal cell cancer, and recurrent glioblastomas. Its approval by US FDA was issued with a black box warning that its use has been associated with a risk of gastrointestinal (GI) tract perforation and that it should be discontinued in patients who have experienced such. The reported incidence of GI perforation in those receiving bevacizumab is as high as 3%. However, the incidence of GI perforation in those receiving bevacizumab undergoing GI endoscopic procedures has not been well studied. METHODS: A retrospective, single-center observational study was conducted at Memorial Sloan Kettering Cancer Center (MSKCC) between 2011 and 2018. All patients who underwent upper GI endoscopy with percutaneous endoscopic gastrostomy (PEG) or percutaneous endoscopic jejunostomy (PEJ) tube placement and received bevacizumab within 6 months of their endoscopic procedure were included. RESULTS: We identified 176 patients who underwent PEG or PEJ tube placement and received bevacizumab within 6 months. Eighty-one percent of patients were female (n = 144) and the median age was 61 years. Prior to endoscopic procedures, patients received a median of seven doses of bevacizumab. Patients received bevacizumab from 170 days before to 170 days after their endoscopic procedures (median 44 days). No GI perforations were observed during or after the time of the endoscopic procedures. CONCLUSION: Our study demonstrated that receiving bevacizumab within 6 months prior to their endoscopic procedure was not associated with an increased risk of GI tract perforation and thus not an absolute contraindication to proceeding with PEG and PEJ tube placement in these patients.

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.

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.

BACKGROUND AND AIMS: The aim of this study was to evaluate the feasibility and early safety of catheter-directed irreversible electroporation (IRE) of the normal common bile duct (CBD) in swine. METHODS: IRE (2000 V, 90 pulses, 100 µs pulse) was performed in the CBD of 6 Yorkshire pigs using a catheter electrode under endoscopic guidance. Ductal patency was assessed with immediate retrograde cholangiography and contrast-enhanced CT imaging at 1 or 7 days after treatment. Animals were killed at either 1 day (n = 4, 2 ablations/animal) or 7 days (n = 2, 1 ablation/animal) after treatment. The biliary tract was extracted en bloc and the length of the ablation along the CBD mucosa was measured. The depth of ablation was quantified using cross-sections of the treated CBD wall stained with hematoxylin and eosin. Single-sample hypothesis testing was performed to verify whether the depth of ablation in the CBD was a representative outcome of IRE treatment. RESULTS: IRE of the CBD did not result in perforation or obstruction of the organ at 1 or 7 days after treatment. The length of ablation along the CBD mucosa was 17.27 ± 5.55 mm on day 1 samples, and transmural ablation of the CBD wall was a representative outcome of the treatment (7/8 samples, P < .05). Day 1 samples demonstrated loss of epithelium, transmural necrosis, with preservation of lumen integrity. Day 7 samples demonstrated re-epithelialization, with diffuse transmural fibrosis of the CBD wall. These findings were absent from sham tissue samples. CONCLUSIONS: Intraluminal catheter-directed IRE is feasible and safe for full-thickness ablation of the normal porcine CBD without affecting lumen patency up to 1 week after treatment.

BACKGROUND AND AIMS: Colonic stent placement in patients with large-bowel obstruction (LBO) secondary to extracolonic malignancy (ECM) has been evaluated in small series with heterogeneous results. Our aim is to better characterize the technical and clinical success of colonic stent placement and to identify factors that affect this success in ECM patients. METHODS: All patients at a single high-volume center who presented for colonic stent placement for LBO because of ECM between 2001 and 2012 were retrospectively identified. The outcomes of interest were technical success, clinical success, stent occlusion rate, and overall survival. RESULTS: A total of 187 patients were identified. Mean age was 61.9 years (range, 23-89), and 150 (80.2%) were women. The most common malignancy type was urogynecologic (n = 104) and most common location sigmoid colon (n = 128). Overall, 142 patients (75.9%) achieved technical success and 102 patients (54.5%) clinical success. Radiographic presence of peritoneal carcinomatosis (P < .001) and multifocal disease (P < .001) were associated with both decreased technical and clinical success. Procedure-related adverse events were seen in 12 patients (6.4%). In patients with clinical success, the incidence of stent occlusion at 3 months was 14.7% (95% confidence interval, 7.8%-21.6%) and was higher in patients with prior radiation therapy (P = .011). The median overall survival for all patients from time of attempted stent placement was 3.3 months (95% confidence interval, 3.0-4.1). CONCLUSIONS: This study represents the largest retrospective series of colonic stent placement for LBO in ECM patients in the literature. Our technical success rate of 75.9%, clinical success rate of 54.5%, and 3-month stent occlusion rate of 14.7% suggest that stent placement is a viable palliative option for patients with advanced disease because of ECM. Patients with peritoneal carcinomatosis and multifocal disease have reduced technical and clinical success. However, these factors should not dissuade an attempt at stent placement, if risk-to-benefit analysis is favorable.

BACKGROUND: Patients with prior pancreaticobiliary or distal gastric cancer treated surgically may have local anastomotic recurrence with obstruction of the afferent and efferent jejunal limbs. This report describes the efficacy and safety of simultaneous endoscopic insertion of self-expanding metal stents into the afferent and efferent jejunal limbs in patients with gastric outlet obstruction (GOO) of post-surgical anatomy for palliation of recurrent malignancy. METHODS: Patients were identified from an endoscopic database at a specialized cancer center between September 2007 and March 2014. Technical success was defined as single-session insertion of afferent and efferent jejunal limb enteral stents. Clinical success was defined as immediate symptom relief and ability to advance diet. A durable response was defined as symptom relief of at least 60 days or until hospice placement or death. RESULTS: Twenty-three patients were identified who underwent insertion of two 22-mm-diameter uncovered duodenal stents. Stent length varied from 60 to 120 mm. Stents were placed under endoscopic and fluoroscopic guidance. Three patients required balloon dilation to facilitate stent insertion. Average procedure time was 58.8 min (range 28-120). Technical success was achieved in 23/24 (96%) patients. Clinical success was achieved in 19/23 (83%) patients. Following initial stent insertion and prior to subsequent re-intervention, 11/19 (58%) patients had a durable response with a median duration of 70 days (range 4-315). Eight (42%) patients underwent subsequent re-intervention at a median of 22 days (range 11-315). Five patients had stent revision and were able to tolerate oral intake. Two patients had percutaneous endoscopic gastrostomy/jejunostomy insertion. One patient required surgical diversion for persistent obstruction. Complications included stent migration and post-stent insertion bacteremia due to food bolus obstruction. CONCLUSIONS: Recurrent malignant GOO in patients with post-surgical anatomy treated with simultaneous endoscopic enteral stenting of afferent and efferent jejunal limbs has a high rate of technical and clinical success and low rate of complications and provides effective palliation.

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.

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.
