Statistical analysis indicated that diverticulopexy, as compared with diverticulectomy, allowed reduced postoperative complications and slightly improved long-term swallowing. Diverticulopexy is feasible also in large Zenker's diverticula and can achieve equivalent or even better results than diverticulectomy with a smoother postoperative course.

Abstract

The ideal surgical technique for symptomatic Zenker's diverticulum has not been identified yet. Endoscopic treatment, although frequently performed, has not replaced the open cricopharyngeal myotomy, which is still deemed the standard therapy by many dedicated physicians. The management of the diverticular sac after myotomy is still a matter of debate. The aim of this study is to compare the results of diverticulectomy and diverticulopexy after cricopharyngeal myotomy, in homogeneous groups of patients. Thirty-seven patients were treated for Zenker's diverticulum at the same university medical school, but in two different units, with open cricopharyngeal myotomy, associated with diverticulectomy in 17 patients and with diverticulopexy in the remaining. No clinical criteria influenced the different choice of treatment of the diverticular pouch, but only the surgeon's preference. Clinical data, diverticulum size, postoperative course, and complications were analyzed. Patients were followed up for median duration of 37 months (range 12-113 months) through contrast swallow study and clinical evaluation, aided by a specifically conceived questionnaire. Records were analyzed by Mann-Whitney-Wilcoxon test and Fisher's exact test. Homogeneous comparative values for sex, age, diverticulum size, and symptoms were found in the two groups. Statistical analysis indicated that diverticulopexy, as compared with diverticulectomy, allowed reduced postoperative complications and slightly improved long-term swallowing. Diverticulopexy is feasible also in large Zenker's diverticula and can achieve equivalent or even better results than diverticulectomy with a smoother postoperative course.
