Wide disparities in attitudes and practices regarding Type II sphincter of Oddi dysfunction: a survey of expert U.S. endoscopists.

Background: Sphincter of Oddi manometry (SOM) is recommended in the evaluation of suspected Type II sphincter of Oddi dysfunction (SOD2), though its utility is uncertain. Little is known about the practice of expert endoscopists in the United States regarding SOD2.

Methods: An anonymous electronic survey was distributed to 128 expert biliary endoscopists identified from U.

Long-term results of the mucosal ablation of Barrett's esophagus: efficacy and recurrence.

Background And Study Aims: It has been postulated that the endoscopic ablation of Barrett's esophagus can lead to complete eradication of the disease. This study was undertaken to evaluate the efficacy of endoscopic eradication therapy for Barrett's esophagus and the rates of recurrence of intestinal metaplasia.

Patients And Methods: As part of an initial randomized controlled trial, patients with nondysplastic or low grade dysplastic Barrett's esophagus underwent mucosal ablation.

Cap assisted colonoscopy for the detection of serrated polyps: a post-hoc analysis.

Background: Colonoscopy offers limited protection against right-sided colon cancer, a significant proportion of which arise from the serrated pathway of carcinogenesis. The aim of this study was to compare cap-assisted colonoscopy and standard high-definition white light colonoscopy regarding serrated polyps' detection.

Methods: Post hoc analysis was performed of a previously conducted randomized controlled trial comparing standard and cap-assisted colonoscopy for adenoma detection.

Physician assessment and management of complex colon polyps: a multicenter video-based survey study.

Objectives: The management of complex colorectal polyps varies in practice. Accurate descriptions of the endoscopic appearance by using a standardized classification system (Paris classification) and size for complex colon polyps may guide subsequent providers regarding curative endoscopic resection vs. need for surgery.

Endoscopic mucosal resection results in change of histologic diagnosis in Barrett's esophagus patients with visible and flat neoplasia: a multicenter cohort study.

Background: There are limited data on the effect of endoscopic mucosal resection (EMR) on changes of histopathologic diagnosis for Barrett's esophagus (BE) patients undergoing endoscopic eradication therapy (EET); especially those without visible lesions.

Aim: To compare the frequency of changes of diagnosis by EMR compared with pre-EMR biopsy diagnosis for patients with and without visible lesions.

Methods: In this multicenter outcomes project, patients with Barrett's-related neoplasia undergoing EET at three tertiary-care centers were included.

Learning curves for EUS by using cumulative sum analysis: implications for American Society for Gastrointestinal Endoscopy recommendations for training.

Background: American Society for Gastrointestinal Endsocopy (ASGE) guidelines for assessing minimal competence in EUS are based on expert opinion and retrospective studies.

Objective: To prospectively define learning curves in EUS among advanced endoscopy trainees (AETs).

Design: Prospective trial.

Management of low-grade dysplasia in Barrett's esophagus.

Purpose Of Review: This article discusses the various controversies that surround the management of low-grade dysplasia (LGD) in Barrett's esophagus.

Recent Findings: Data on the clinical course of LGD patients with regards to rates of progression to high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC) are highly variable. Recent data suggest that the rate of progression to EAC may be similar to that of patients with nondysplastic Barrett's esophagus (0.
