Endoscopic transoral stapling of Zenker's diverticula

The pharyngoesophageal pouch was first described by Ludlow in 1764 and later by Zenker. It is a pulsion diverticulum of the posterior pharynx, arising in Killian's triangle. Zenker's diverticula are related to a non-compliant upper esophageal sphincter and have been associated with gastroesophageal reflux. Surgical therapy has been recommended for dysphagia and regurgitation. Many surgical options exist. More recently, minimally invasive, transoral stapling has been used. Transoral stapling may be a less morbid operation and may allow patients a quicker return to oral diet and usual activities.
