Recurrence Is Rare Following Complete Eradication of Intestinal Metaplasia in Patients With Barrett's Esophagus and Peaks at 18 Months.

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.

Effect of individualized feedback on learning curves in EGD and colonoscopy: a cluster randomized controlled trial.

Background And Aims: Gastroenterology fellowships need to ensure that trainees achieve competence in upper endoscopy (EGD) and colonoscopy. Because the impact of structured feedback remains unknown in endoscopy training, this study compared the effect of structured feedback with standard feedback on trainee learning curves for EGD and colonoscopy.

Methods: In this multicenter, cluster, randomized controlled trial, trainees received either individualized quarterly learning curves or feedback standard to their fellowship.

A Prospective Multicenter Study Evaluating Endoscopy Competence Among Gastroenterology Trainees in the Era of the Next Accreditation System.

Purpose: The Next Accreditation System requires training programs to demonstrate competence among trainees. Within gastroenterology (GI), there are limited data describing learning curves and structured assessment of competence in esophagogastroduodenoscopy (EGD) and colonoscopy. In this study, the authors aimed to demonstrate the feasibility of a centralized feedback system to assess endoscopy learning curves among GI trainees in EGD and colonoscopy.

Endoscopic Ultrasound Placement of Preloaded Fiducial Markers Shortens Procedure Time Compared to Back-Loaded Markers.

Background & Aims: Fiducial markers are inert radiopaque gold or carbon markers implanted in or near pancreatic tumor to demarcate areas for image-guided radiation therapy. Endoscopic ultrasound (EUS) pre-loaded fiducial needles (PLNs) have been developed to circumvent technical issues associated with traditional back-loaded fiducials (BLNs). We performed a randomized controlled trial to compare procedure times in patients with pancreatic adenocarcinoma undergoing EUS-guided placement of BLNs vs PLNs.

Anatomic location of Barrett's esophagus recurrence after endoscopic eradication therapy: development of a simplified surveillance biopsy strategy.

Background And Aims: Surveillance endoscopy is recommended after endoscopic eradication therapy (EET) for Barrett's esophagus (BE) because of the risk of recurrence. Currently recommended biopsy protocols are based on expert opinion and consist of sampling visible lesions followed by random 4-quadrant biopsy sampling throughout the length of the original BE segment. Despite this protocol, some recurrences are not visibly identified.

Development and validation of a video-based cold snare polypectomy assessment tool (with videos).

Background And Aims: Polyps <1 cm are the most commonly found polyps during colonoscopy. Cold snare removal is preferred given the significantly higher rate of incomplete resection associated with piecemeal biopsy forceps resection. There are currently no standardized tools to assess competence in cold snare polypectomy.
