Endoscopic Staple Diverticulostomy for Zenker’s Diverticulum

Objective: Surgical treatment of Zenker’s diverticulum (ZD) has evolved over the previous 2 decades to a predominantly endoscopic approach. In this study, we review our experience with endoscopic staple-assisted diverticulostomy (ESD) for treatment of ZD from 2002 to 2011. Methods: Retrospective chart review of 359 primary and revision ESD procedures performed on 337 unique patients between September 2002 and December 2011. Data were tabulated for age, sex, size of diverticulum, time to symptom recurrence, complications, and relief of symptoms. Results: Of 337 attempted primary ESD procedures, 3.9% (N = 13) were aborted due to inadequate exposure. Of 324 patients who underwent primary ESD, 93.8% (N = 304) reported postoperative improvement of dysphagia symptoms. There was a 4.0% (N = 13) major complication rate. Patient-reported recurrence of symptoms occurred in 7.1% (N = 23) of primary ESD patients but was not significantly associated with diverticulum size (P = .9765). Twenty-one patients underwent revision ESD, with 95% (N = 20) of patients reporting improvement and 4.8% (N = 1) developing recurrent symptoms. Conclusion: Primary and revision ESD were shown to have similar success at relieving the symptoms of ZD, with low procedure abandonment and perioperative complication rates. Further patient follow-up is needed to determine the durability of symptom improvement and ZD recurrence rate following ESD.
