Epiphrenic diverticula: minimal invasive approach and repair in five patients.

Epiphrenic esophageal diverticula are rare and often asymptomatic. If surgery is mandatory, a thoracotomy is used to resect the diverticulum. The results of a minimal invasive approach and repair in five patients are presented. These patients, who all presented with an epiphrenic diverticulum, were evaluated using barium swallow study, esophagoscopy, and manometry. The diverticula were approached by thoracoscopy in all patients and a description of the surgical technique is given. The diverticula were resected using a right-sided approach in four patients. One patient with a diverticulum in the distal esophagus required conversion to laparoscopy. A myotomy was performed in two patients because of high pressures in the lower esophageal sphincter. The postoperative course was uncomplicated in four patients. One patient with Ehlers-Danlos disease had a complicated course owing to leakage, resulting in two re-operations by means of thoracotomy. There was no mortality. The minimal invasive approach of epiphrenic diverticula is feasible. The long-term results are awaited.
