The endoscopic stapler diverticulotomy for Zenker's diverticulum.

This paper describes the surgical procedure of the endoscopic stapler treatment of Zenker's diverticulum and analyzes the results of 24 consecutive operated patients. In three patients the endoscopic exposure of the diverticulum was not possible. Twenty-one patients underwent endoscopic stapler treatment without any peri- or postoperative complications. The follow-up period was 4 to 29 months (average 18 months). The average total time for surgery was 25 min. Postoperatively, a nasogastric feeding tube was not necessary: all patients resumed oral intake 12 h after surgery. Discharge from the hospital followed the 2nd postoperative day. All patients had complete or nearly complete resolution of symptoms at the 4-month follow-up. Recurrent complaints were an indication for repeat of the contrast barium esophagram. Two patients revealed a residual diverticulum 7 and 11 months after treatment. In comparison with results and complication rates in the literature of the external, transcutaneous techniques and endoscopic diverticulotomy procedures, the endoscopic stapler treatment of Zenker's diverticulum is a safe, (cost-)effective and minimally invasive method and to be considered as the initial treatment of choice.
