The aim of the Expert Approach section is to contribute to the dissemination and standardization of new endoscopie procedures. Authors from three distinct geographic areas combine forces, sharing their experience to form a consensus of opinion. Readers' comments are welcome and will be published in the Mailbox which appears at the end of each Expert Approach article.Committee:Chairman: R. Lambert (Lyon)Specialists: R. Kozarek (Seattle), H.

Introduction

The pharyngoesophageal diverticulum has been called Zenker's diverticulum (ZD); we define the latter as a posterior diverticulum with its neck proximal to the cricopharyngeal muscle. Most authors consider such pouches to be a type of esophageal diverticulum. Diverticula are outpouchings of one or more layers of the esophageal wall, and occur in three main areas: 1) immediately above the upper esophageal sphincter (ZD); 2) near the midpoint of the esophagus (traction diverticulum); and 3) immediately above the lower esophageal sphincter (epiphrenic diverticulum).
