Risk factors for SARS-CoV-2 are unique to this population and include crowded living conditions, isolated social networks, and exploitative working environments. The circumstances and cultural values of Latinx seasonal farmworkers pose a unique challenge to public health authorities working to contain the spread of SARS-CoV-2.

A cooperative approach for treatment of Zenker's diverticulum.

Background: Symptomatic Zenker's diverticulum management has evolved from an open intervention to an endoscopic management. At our center, both an otolaryngologist and a gastroenterologist are present in the operating room when treating these lesions. An intra-procedural consensus is reached to undergo either rigid endoscopy or flexible endoscopic diverticulotomy with ENT guidance.

Kimura-Takemoto Classification: A Tool to Predict Gastric Intestinal Metaplasia Progression to Advanced Gastric Neoplasia.

Background And Aims: Gastric cancer is a leading cause of morbidity and mortality worldwide. Gastric intestinal metaplasia (GIM) has been described as a key histologic step in the development of gastric adenocarcinoma. However, not all people with GIM develop malignancy.

Orthotopic Liver Transplantation in a Cirrhotic Patient With Recent COVID-19 Infection.

The coronavirus disease 2019 (COVID-19) pandemic has led to a decrease in liver transplantation because of concerns regarding safety and healthcare resource utilization. There are scant data regarding the safety, optimal timing, and preferred postsurgical immunosuppression regimens for liver transplantation in patients recovered from COVID-19 infection. We describe our experience with one of the first reported cases of orthotopic liver transplantation in a patient who had recently recovered from COVID-19 infection.

Chronic Intestinal Pseudo-Obstruction Due to Incidentally Found Thymoma.

Chronic intestinal pseudo-obstruction is a severe gastrointestinal tract disorder mimicking a bowel obstruction with no mechanical causes. Our patient presented with bowel obstruction symptoms, and a thymoma was incidentally found during the diagnostic workup. After failing conservative management, the patient underwent exploratory laparotomy that showed negative results for a mechanical cause of obstruction.

From hepatitis A to E: A critical review of viral hepatitis.

Viral infections affecting the liver have had an important impact on humanity, as they have led to significant morbidity and mortality in patients with acute and chronic infections. Once an unknown etiology, the discovery of the viral agents triggered interest of the scientific community to establish the pathogenesis and diagnostic modalities to identify the affected population. With the rapid scientific and technological advances in the last centuries, controlling and even curing the infections became a possibility, with a large focus on preventive medicine through vaccination.

Clinical and Endoscopic Predictors of Hydrostatic Balloon Dilation Failure for Post-Bariatric Anastomotic Stricture Treatment.

Background: Roux-en-Y gastric bypass (RYGB) patients can develop anastomotic strictures. The initial management relies on endoscopic hydrostatic balloon dilation, but in a subset of patients, it may be unsuccessful despite several dilations, requiring a different treatment modality. We evaluated the factors associated with balloon dilation failure and need for revision surgery.

Early Detection of Hepatocellular Carcinoma Recurrence in the Posttransplant Population: A Comparison of RETREAT and Cleveland Clinic Florida Scoring System.

Background: Liver transplantation (LT) for hepatocellular carcinoma (HCC) is curative in most cases; however, recurrence is observed in some patients. The Risk Estimation of Tumor Recurrence After Transplant (RETREAT) score is an externally validated scoring system for prediction of post-LT HCC recurrence. The Cleveland Clinic Florida Scoring System (CCFSS) is a potential new scoring system for prediction of HCC recurrence.

Hyperbaric Oxygen Therapy in Chronic Inflammatory Conditions of the Pouch.

Background: Pouchitis can be a chronic complication of ileal pouch-anal anastomosis. We aimed to determine the efficacy and safety of hyperbaric oxygen therapy (HBOT) for chronic antibiotic-refractory pouchitis (CARP) and other inflammatory conditions of the pouch.

Methods: This was a retrospective case series of adults with inflammatory bowel disease (IBD) who underwent ileal pouch-anal anastomosis and then developed CARP and received HBOT between January 2015 and October 2019.

Increased Sessile Serrated Adenoma Detection Rate With Mechanical New Technology Devices: A Systematic Review and Meta-Analysis.

Goal: This meta-analysis aims to compare the sessile-serrated adenoma detection rate (SSADR) of currently available mechanical new technology devices (NTDs) to conventional colonoscopy (CC).

Background: NTDs including Endocuff, EndoRing, G-Eye, and AmplifEYE were developed with the aim of improving adenoma detection rate by enhancing colonic mucosal visualization. Increasing awareness of the risk of sessile-serrated adenoma progression to malignancy has ushered a need to increase the detection of these characteristically flat lesions.

Anastomotic Ulcers After Ileocolic Resection for Crohn's Disease Are Common and Predict Recurrence.

Background: Crohn's disease recurrence after ileocolic resection is common and graded with the Rutgeerts score. There is controversy whether anastomotic ulcers represent disease recurrence and should be included in the grading system. The aim of this study was to determine the impact of anastomotic ulcers on Crohn's disease recurrence in patients with prior ileocolic resections.

Association Between Indefinite Dysplasia and Advanced Neoplasia in Patients With Inflammatory Bowel Diseases Undergoing Surveillance.

Background & Aims: Little is known about the clinical significance of indefinite dysplasia (IND) in patients with inflammatory bowel diseases (IBD) undergoing colonoscopic surveillance for colorectal neoplasia.

Methods: We conducted a retrospective cohort analysis of 492 patients with colonic IBD for 8 or more years or concomitant primary sclerosing cholangitis, with no history of advanced colorectal neoplasia (high-grade dysplasia or colorectal cancer) or colectomy, undergoing colorectal neoplasia surveillance at a tertiary IBD referral center from 2001 through 2017. Subjects received consistent histopathologic grading of dysplasia.

Hormone Therapy for Cancer Is a Risk Factor for Relapse of Inflammatory Bowel Diseases.

Background & Aims: Exposure to hormone contraception has been associated with an increased risk of relapse of inflammatory bowel diseases (IBDs). Little is known about the effects of cancer therapies, specifically hormone therapies, on the course of IBD.

Methods: We conducted a retrospective cohort study, collecting data from 5 medical centers, on patients with IBD who received a subsequent diagnosis of breast or prostate cancer from 1997 through 2018.

No Association Between Pseudopolyps and Colorectal Neoplasia in Patients With Inflammatory Bowel Diseases.

Background & Aims: Patients with inflammatory bowel diseases who have postinflammatory polyps (PIPs) have an increased risk of colorectal neoplasia (CRN). European guidelines propose that patients with PIPs receive more frequent surveillance colonoscopies, despite limited evidence of this increased risk. We aimed to define the risk of CRN and colectomy in patients with inflammatory bowel diseases and PIPs.

Statin Exposure Is Not Associated with Reduced Prevalence of Colorectal Neoplasia in Patients with Inflammatory Bowel Disease.

Background/aims: Statins have been postulated to lower the risk of colorectal neoplasia. No studies have examined any possible chemopreventive effect of statins in patients with inflammatory bowel disease (IBD) undergoing colorectal cancer (CRC) surveillance. This study examined the association of statin exposure with dysplasia and CRC in patients with IBD undergoing dysplasia surveillance colonoscopies.

Consecutive negative findings on colonoscopy during surveillance predict a low risk of advanced neoplasia in patients with inflammatory bowel disease with long-standing colitis: results of a 15-year multicentre, multinational cohort study.

Objectives: Surveillance colonoscopy is thought to prevent colorectal cancer (CRC) in patients with long-standing colonic IBD, but data regarding the frequency of surveillance and the findings thereof are lacking. Our aim was to determine whether consecutive negative surveillance colonoscopies adequately predict low neoplastic risk.

Design: A multicentre, multinational database of patients with long-standing IBD colitis without high-risk features and undergoing regular CRC surveillance was constructed.

New technologies improve adenoma detection rate, adenoma miss rate, and polyp detection rate: a systematic review and meta-analysis.

Background And Aims: The need to increase the adenoma detection rate (ADR) for colorectal cancer screening has ushered in devices that mechanically or optically improve conventional colonoscopy. Recently, new technology devices (NTDs) have become available. We aimed to compare the ADR, polyp detection rate (PDR), and adenoma miss rate (AMR) between NTDs and conventional colonoscopy and between mechanical and optical NTDs.

Single Center Experience of a New Endoscopic Clip in Managing Nonvariceal Upper Gastrointestinal Bleeding.

Background: To assess the safety and efficacy of the Instinct clip in the acute endoscopic treatment of upper gastrointestinal bleeding (UGIB).

Materials And Methods: This is the first large series reporting this clip in achieving hemostasis. A retrospective descriptive chart review was performed on patients presenting with recent overt GI bleeding treated with endoclip therapy at Mount Sinai Beth Israel Medical Center between May 2013 and January 2016.

High Risk of Advanced Colorectal Neoplasia in Patients With Primary Sclerosing Cholangitis Associated With Inflammatory Bowel Disease.

Background & Aims: Patients with inflammatory bowel disease (IBD) and primary sclerosing cholangitis (PSC, termed PSC-IBD) are at increased risk for colorectal cancer, but their risk following a diagnosis of low-grade dysplasia (LGD) is not well described. We aimed to determine the rate of advanced colorectal neoplasia (aCRN), defined as high-grade dysplasia and/or colorectal cancer, following a diagnosis of indefinite dysplasia or LGD in this population.

Methods: We performed a retrospective, longitudinal study of 1911 patients with colonic IBD (293 with PSC and 1618 without PSC) who underwent more than 2 surveillance colonoscopies from 2000 through 2015 in The Netherlands or the United States (9265 patient-years of follow-up evaluation).
