Endoscopic ultrasonography

Introduction

The 2012 Digestive Disease Week (DDW; 19 – 22 May 2012, San Diego, California, USA) featured exciting research from the field of endoscopic ultrasonography (EUS). The research highlights continued to focus on tissue acquisition and interventional EUS. Although overall there were fewer novel EUS applications presented, the quality of research, as evidenced by more prospective randomized trials, was generally higher than in previous years. In this review, the top 20 EUS abstracts from DDW 2012 are identified and key aspects are discussed.
