From 1976 to 1996, thirty nine patients were surgically treated for pharyngoesophageal diverticulum. The present study aimed to compare two methods of operative treatment of Zenker's diverticulum: excision (group I) and pexy, both of which were associated with upper esophageal sphincter myotomy. The main indication for surgery was dysphagia. The diagnosis of Zenker's diverticulum was based on clinical symptoms and the result of upper GI tract barium examination. In 75% of patients the diameter of diverticulum exceeded 2 cm. No patient died in the perioperative period. The main complications observed in the postoperative period were of pulmonary origin. In group I (excision) a leakage from the suture line occurred in 2 patients (12.5%). Time of follow-up ranged from 1 to 20 years (mean: 7 years). The comparison of both methods of treatment employed is in favour of diverticulopexy, being a safer and less complications-bearing method, although both of them give similar functional results.
