Zenker's diverticulum.

Symptomatic Zenker's diverticula are usually treated with diverticulectomy and myotomy. Other, more conservative open procedures consist of diverticulopexy, imbrication, and myotomy alone. These more conservative procedures do not result in a breach of esophageal mucosa and should have more rapid postoperative recovery. We performed a retrospective chart review of all open surgical procedures performed at the Marshfield Clinic and St. Joseph's Hospital between 1975 and 1996. Using Wilcoxon's rank sum test, the conservative procedures were compared with the standard diverticulectomy for duration of hospitalization and length of time to resumption of oral intake. Fifty-nine patients are reported. Statistically significant differences between the surgery groups were found for hospitalization (P < 0.001) and days to resumption of oral intake (P < 0.001). Conservative open surgical procedures for repair of Zenker's diverticula result in decreased hospitalization and earlier resumption of oral diet compared with diverticulectomy.
