Minimally Invasive Management of Epiphrenic Esophageal Diverticula

The purpose of this study is to review our initial experience with a minimally invasive approach to manage symptomatic epiphrenic esophageal diverticula. Five patients with symptomatic epiphrenic esophageal diverticula underwent surgical management between August 1997 and December 2002. All patients complained of dysphagia; had experienced symptoms for at least 12 months; and were evaluated preoperatively by a barium esophagram, esophagogastroduodenoscopy, and esophageal manometry. The epiphrenic esophageal diverticula measured 5 cm or less in all patients. Manometry demonstrated esophageal dysmotility in three patients. A minimally invasive technique was completed in all five patients. Four patients underwent laparoscopic diverticulectomy and myotomy including a concomitant Toupet fundoplication, and one patient underwent thoracoscopic diverticulectomy and myotomy. The mean operative time was 245 minutes (range 175–334). The longest operative time was for the thoracoscopic procedure. The estimated blood loss was minimal (range 30–100 cm 3 ). The laparoscopic patients had a mean postoperative length of stay of 2.75 days (range 2–4) and the patient undergoing a thoracoscopic approach was discharged on postoperative day 6 due to a history of lung disease and home oxygen requirements. There were no other postoperative complications. After a mean follow-up of 16.2 months (range 3–36) all patients are asymptomatic. Short-term follow-up after our initial experience with minimally invasive approaches for epiphrenic esophageal diverticula demonstrates that thoracoscopic and laparoscopic approaches are feasible; safe; and effectively alleviate dysphagia, regurgitation, and other associated symptoms. Long-term outcomes should be monitored during the evolution of these novel minimally invasive techniques to ensure outcomes comparable to those of a transthoracic open approach.
