Endoscopic stapling diverticulostomy for Zenker's diverticulum.

Endoscopic stapling diverticulostomy (ESD) using an endostapler is a modification of the standard endoscopic treatment of Zenker's diverticulum (ZD). It is characterized by complete myotomy of the upper esophageal sphincter, with division of the common wall between diverticulum and esophagus, followed by immediate simultaneous closure of the divided edges with the staples. ESD was performed on 21 patients with ZD between January 1996 and October 1997. The results were then evaluated. Operation time averaged 22 min. Wide opening of the diverticulum and excellent hemostasis were achieved. All of the patients but one, who died postoperatively of myocardial infarction, resumed oral intake without any evidence of cervical sepsis or mediastinitis. Complete relief of dysphagia was achieved in all 20 patients. Hospital stay averaged 4.7 days (range, 2-7 days). The patients were followed up after ESD for a median time period of 12 months. No relapses were recorded. ESD is an effective endoscopic treatment for ZD that entails a low risk of complications and requires only a short period of hospitalization.
