In a retrospective study of patients undergoing drainage of pancreatic pseudocysts or walled-off necrosis, we found LAMS and DPS to have comparable rates of technical and clinical success and adverse events. Drainage of walled-off necrosis or pancreatic pseudocysts using DPS was associated with fewer bleeding events overall, including pseudoaneurysm bleeding, but bleeding risk with LAMS should be weighed against the trend of higher actionable perforation and infection rates with DPS.
In this prospective multicenter study, we found that although competence cannot be confirmed for all AETs at the end of training, most meet QI thresholds for EUS and ERCP at the end of their first year of independent practice. This finding affirms the effectiveness of training programs. Clinicaltrials.gov ID NCT02509416.
Background and Aims-Minimum EUS and ERCP volumes that should be offered per trainee in "high quality" advanced endoscopy training programs (AETPs) are not established. We aimed to define the number of procedures required by an "average" advanced endoscopy trainee (AET) to achieve competence in technical and cognitive EUS and ERCP tasks to help structure AETPs. Methods-ASGE-recognized AETPs were invited to participate; AETs were graded on every fifth EUS and ERCP examination using a validated tool. Grading for each skill was done using a 4-point scoring system and learning curves (LCs) using cumulative sum (CUSUM) analysis for overall, technical, and cognitive components of EUS and ERCP were shared with AETs and trainers quarterly. Generalized linear mixed effects models with a random intercept for each AET were used to generate aggregate LCs allowing us to use data from all AETs to estimate the average learning experience for trainees. Results-Among 62 invited AETPs, 37 AETs from 32 AETPs participated. The majority of AETs reported hands-on EUS (52%, median 20 cases) and ERCP (68%, median 50 cases) experience before starting an AETP. The median number of EUS and ERCPs performed/AET was 400 (range 200-750) and 361 (250-650), respectively. Overall, 2616 examinations were graded
BACKGROUND & AIMS:There have been few studies describing the long-term durability of complete eradication of intestinal metaplasia (CE-IM) in patients with Barrett's esophagus (BE)-related neoplasia who received endoscopic eradication therapy (EET). Data are needed to guide surveillance interval protocols and identify patients at risk for recurrence. We assessed the rate of recurrence of intestinal metaplasia and dysplasia, histologic features, and outcomes after recurrence of CE-IM, and identified factors associated with recurrence.
METHODS:We performed a prospective study of 807 patients with BE who underwent EET, which produced CE-IM, at 4 tertiary-care referral centers, from January 2013 to October 2018. Kaplan-Meier estimates of cumulative incidence rates (IR) of recurrence were calculated for up to 5 years following CE-IM and were stratified by baseline level of histology. Density estimates of recurrence were used to determine the change in the rate of recurrence over time. We conducted logistic regression analysis to identify factors associated with recurrence.
RESULTS:Intestinal metaplasia recurred in 121 patients (15%; IR, 5.2/100 person-years), and dysplasia recurred in 41 patients (5.1%; IR, 1.8/100 person-years), after a median follow-up time of 2317 person-years. The rate of recurrence was not constant and the time to any recurrence converged to a normal distribution; recurrences peaked at 1.6 y after patients had CE-IM. Baseline high-grade dysplasia or intramucosal cancer (adjusted odds ratio [aOR], 4.19), presence of reflux symptoms (aOR, 12.1) or hiatal hernia (aOR, 13.8), and number of sessions required to achieve CE-IM (aOR, 1.8) were associated with recurrence.
CONCLUSIONS:In a prospective study of a large cohort of patients with BE undergoing EET, we found a low rate of recurrence after CE-IM. The rate of recurrence peaked at 1-2 y after CE-IM. These findings indicate that aggressive surveillance might not be necessary more than 1 y after CE-IM and should be considered in surveillance guidelines. Clinicaltrials.gov no: NCT02634645.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
