Preliminary assessment of two novel mechanical colonoscopic polypectomy simulators: Description, evaluation and validation.

Colonoscopic polypectomy is an essential endoscopic skill. The simulators available for training are limited and based on raw porcine colons. Animal intestines are inconvenient and offer limited advantages for polypectomy training.

Comparison of endoscopic sphincterotomy techniques after Billroth II gastrectomy using a novel mechanical simulator.

Background And Aims: A postsurgical anatomy renders endoscopic sphincterotomy (EST) more challenging. Although different EST techniques for such a situation exist, comparative studies are lacking. The aim of the study was to compare the efficacy of different EST techniques using a novel mechanical simulator.

A novel mechanical simulator for cannulation and sphincterotomy after Billroth II or Roux-en-Y reconstruction.

Introduction: In patients with Billroth II (B II) or Roux-en-Y anatomy, endoscopic retrograde cholangiopancreatography (ERCP) is demanding. Here, we describe a novel simulator with simulated fluoroscopy for cannulation and sphincterotomy training in such situations.

Methods: A custom-made simulation system was built based upon a common chassis of a series of previously described ERCP simulators.

A new peroral mother-baby endoscope system for biliary tract disorders.

Aim: To investigate a new mother-baby system, consisting of a peroral cholangioscope and a duodenoscope in patients regarding its feasibility.

Methods: In the study period from January 2007 to February 2010, 76 consecutive patients (33 men, 43 women; mean age 63 years old) were included in this pilot series. Endoluminal images and biopsies were obtained from 55 patients with indeterminate strictures, while 21 patients had fixed filling defects.

Prospective randomized comparison of short-access mother-baby cholangioscopy versus direct cholangioscopy with ultraslim gastroscopes.

Background: Mother-baby technologies, the criterion standard for cholangioscopy, have several limitations. A novel, short-access, mother-baby (SAMBA) system may improve this technique. Direct cholangioscopy (DC) was recently developed as an alternative to mother-baby cholangioscopy.
