Improved specimen adequacy using jumbo biopsy forceps in patients with Barrett's esophagus.

Aim: To assess the sampling quality of four different forceps (three large capacity and one jumbo) in patients with Barrett's esophagus.

Methods: This was a prospective, single-blind study. A total of 37 patients with Barrett's esophagus were enrolled.

Training of different endoscopic skills on ex-vivo animal model.

Introduction: Virtual reality simulator and ex vivo animal models are used for training of both basic and advanced endoscopic techniques. The aim of this study was to assess whether hands-on training on ex vivo animal model improves endoscopic skills. Four different endoscopic techniques were practiced: endoscopic resection, endoscopic stenting, application of the over-the-scope (OVESCO) clip, and endoscopic submucosal dissection (ESD).

Training on an ex vivo animal model improves endoscopic skills: a randomized, single-blind study.

Background: Animal models are used for training of different endoscopic procedures. Whether this really improves endoscopic skills remains controversial.

Objective: To assess the effectiveness of training by using an ex vivo animal gastric model on the performance of two therapeutic procedures-hemostasis and treatment of perforation.
