UEGW 2011 Report: Putting endoscopy into perspective

Introduction

The 19th United European Gastroenterology Week (UEGW; 22 – 26 October 2011; Stockholm, Sweden) presented a unique opportunity for delegates interested in gastrointestinal endoscopy to update their knowledge as colleagues from around the world shared their experiences. Several interesting abstracts on endoscopic topics were presented, allowing participants to become acquainted with the latest advancements and current research in the field of gastrointestinal endoscopy. This report focuses on oral presentations and selected poster presentations and aims to review them in the light of recent literature.
