Pharyngoesophageal diverticulum: evaluation of treatment results.

OBJECTIVE To evaluate the postoperative outcome of patients with pharyngoesophageal diverticulum submitted to surgical and endoscopic treatments. METHODS We retrospectively analyzed 36 patients with pharyngo-esophageal diverticulum treated at the Hospital of the Medical School of Botucatu - UNESP. Patients were divided into two groups, depending on the treatment: group 1 (n = 24): diverticulectomy associated myotomy through a left cervicotomy; group 2 (n = 12): endoscopic diverticulostomy with linear stapler. RESULTS Operative mortality was zero in both groups. Early complications: group 1 - two patients developed cervical fistula and two, hoarseness; group 2 - none. Late complications: group 1 - none; group 2: recurrence of dysphagia in four patients (p = .01). Mean follow-up was 33 months for group 1 and 28 months for group 2. CONCLUSION Both procedures were effective in remission of dysphagia. Surgical treatment showed superiority to endoscopy, with resolution of dysphagia with a single procedure. Endoscopic treatment should be reserved for the elderly and those with comorbidities.
