Laparoscopic resection of esophageal epiphrenic diverticulum

Abstract

Symptomatic esophageal epiphrenic diverticula are usually repaired with a diverticulectomy and esophagomyotomy via a left thoracotomy with substantial postoperative pain and morbidity. If a laparoscopic approach could be shown to be safe and effective, the decrease in postoperative pain and potentially shorter hospital stay would make this technique beneficial. We report three cases repaired via a transabdominal approach. The first two cases were done laparoscopically. The third case was attempted laparoscopically and completed via a midline laparotomy, demonstrating that thoracotomy is not necessary even if laparoscopy is not possible. All three patients had long-standing debilitating symptoms refractory to standard nonsurgical therapies (botulinum toxin injection, pneumatic dilation, antispasmodic medication) with abnormal esophageal motility. There was one intraoperative complication of a left pneumothorax that required neither laparotomy nor thoracostomy. An esophagram on the first postoperative day demonstrated no extravasation and good flow into the stomach. The postoperative course was uneventful for all three patients, with the laparoscopic patients discharged on the second postoperative day and the laparotomy patient discharged on the seventh postoperative day. In conclusion, laparoscopic repair of symptomatic esophageal epiphrenic diverticula is a safe and effective technique with minimal postoperative pain and morbidity. It should be considered as an alternative to the traditional transthoracic approach, and may become the standard technique.
