Laparoscopic surgery for ventrally located epiphrenic diverticulum with esophageal achalasia

Abstract

Epiphrenic diverticulum is frequently associated with esophageal motility disorder, including esophageal achalasia. Heller's myotomy should accompany diverticulectomy to reduce the bulging pressure in surgery for epiphrenic diverticulum with esophageal achalasia. In such cases, designing myotomy is sometimes difficult, depending on the size and location of the diverticulum. Ventrally located diverticula require special caution to spare some muscular tissue between the longitudinal staple line of the diverticulectomy and myotomy, which is a crucial step to prevent staple-line dehiscence. In this article, we describe a case with ventrally located epiphrenic diverticulum who underwent successful laparoscopic resection and myotomy for esophageal achalasia with an informative surgical video.
