Background And Aims: While endoscopic retrograde cholangiopancreatography (ERCP) is a valuable diagnostic and therapeutic tool in primary sclerosing cholangitis (PSC), there is conflicting data on associated adverse events. The aims of this systematic review and meta-analysis are to (1) compare ERCP-related adverse events in patients with and without PSC and (2) determine risk factors for ERCP-related adverse events in PSC.

Methods: Embase, PubMed, and CENTRAL were searched between January 1, 2000, and May 12, 2021.

Importance: There are insufficient data describing the incidence and risk factors of postcolonoscopy complications in older individuals.

Objective: To assess the association between older age (≥75 years) and the risk of postcolonoscopy complications.

Design, Setting, And Participants: This population-based retrospective cohort study included adults (≥50 years) undergoing outpatient colonoscopy between April 2008 and September 2017, identified from Ontario administrative databases.

Background And Aims: Endoscopists are at risk of developing musculoskeletal injuries (MSIs), and few receive training on ergonomics. The aim of this study was to determine the impact of a simulation-based ergonomics training curriculum (ETC) on work-related MSI risk during clinical colonoscopy.

Methods: Novice endoscopists underwent a simulation-based ETC and were compared with an historical control group who received simulation-based training without ergonomics training.

Background And Aims: Non-technical skills (NTS), involving cognitive, social and interpersonal skills that complement technical skills, are important for the completion of safe and efficient procedures. We investigated the impact of a simulation-based curriculum with dedicated NTS training on novice endoscopists' performance of clinical colonoscopies.

Methods: A single-blinded randomized controlled trial was conducted at a single center.

 Novice endoscopists are inaccurate in self-assessment of procedures. One means of improving self-assessment accuracy is through video-based feedback. We aimed to determine the comparative effectiveness of three video-based interventions on novice endoscopists' self-assessment accuracy of endoscopic competence.

Objective: Lymphocytic esophagitis (LyE) is a novel, yet poorly described, clinicopathologic entity. The aim of this systematic review was to characterize the demographic, clinical, endoscopic, and histologic features of LyE in observational studies of adult and pediatric patients.

Design: We searched the Embase, MEDLINE, and SCOPUS databases for relevant studies in 2018.

Background: Non-technical skills (NTS), such as communication and professionalism, contribute to the safe and effective completion of procedures. NTS training has previously been shown to improve surgical performance. Moreover, increases in NTS have been associated with improved clinical endoscopic performance.

Background And Aims: A structured comprehensive curriculum (SCC) that uses simulation-based training (SBT) can improve clinical colonoscopy performance. This curriculum may be enhanced through the application of progressive learning, a training strategy centered on incrementally challenging learners. We aimed to determine whether a progressive learning-based curriculum (PLC) would lead to superior clinical performance compared with an SCC.

Objectives: Over the past two decades, the Omani diet has changed considerably to resemble a high calorie and a low nutrient density Western diet. We investigated the fat soluble nutrient status of children before and after intervention with fish diet or fish oil.

Methods: Children ages 9 and 10 y (n = 314) were recruited from three randomly selected schools.
