Endoscopic diagnosis and treatment of gastric tumors

Introduction

The role of endoscopy in the handling of benign and malignant gastrointestinal tumors continues to expand, due to a combination of increasing sophistication of the equipment and ingenious improvements in the methods used. Traditional white-light surface imaging is increasingly being supplemented by other modalities, and the removal of lesions now carries a strong resemblance to minimally invasive surgery. Summarizing the abstracts from this year’s Digestive Disease Week on the endoscopic handling of gastrointestinal tumors is a vast task because this now comprises the bulk of endoscopic activity. The following summary will concentrate on methods and results related to the handling of gastric lesions.
