Abstract
The authors have previously described the endoscopic staple‐assisted esophagodiverticulostomy (ESED) technique for treatment of Zenker's diverticulum. In the initial series of six patients, ESED was shown to be safe and effective in the short term, with a significant reduction in hospital stay and convalescence as compared with other surgical techniques. This report documents the authors' long‐term experience with ESED (average follow‐up, 9.3 months; range, 1.5 to 25 months) and discusses the long‐term results of this therapy, technical issues, and variations they have utilized, as well as the advantages and limitations of this approach. Thirty‐six patients with Zenker's diverticula have been treated from March 1995 to March 1997. In 34 of the patients, ESED was accomplished, resulting in successful resolution of preoperative symptoms in 32 (94%). Two patients had persistent dysphagia after initial ESED; a revision ESED was successfully performed without complication in both. Two patients were unable to be treated with ESED because of inability to expose the diverticulum with the Weerda laryngoscope. Oral liquid diet has been resumed, on average, 0.8 days after surgery (range, 0 to 4 days), with solid diet resumed by day 5 (range, 1 to 14 days). The average hospital stay has been 1.3 days (range, 1 to 4 days). There have been no postoperative deaths, infections, or airway difficulties. Perioperative morbidity to date has included one case of iatrogenic pharyngeal perforation, one postoperative fever, one transient true vocal fold paralysis, and two dental injuries, with no long‐term sequelae. The results support the use of ESED as the initial treatment of choice for patients with Zenker's diverticula.
