Abstract:
We present an unusual case of a giant, pedunculated esophageal lipoma originating in the mid-esophagus ball-valving through the gastroesophageal junction resulting in intermittent obstruction and hemorrhage. Endoscopic ultrasonography revealed a 1 cm in diameter vessel in the stalk of the polyp, and endoscopic resection was not performed. Transgastric laparoscopic resection with endoscopic guidance was successfully performed using 2 balloon-tipped laparoscopic trocars inserted laparoscopically into the gastric lumen through separate gastrotomies. Intraoperative esophagoscopy confirmed proper port placement and the exact location of the mass. Under direct visualization, a Snowden-Pencer grasper was used to pull the polyp down into the stomach and an Endo-GIA blue articulating stapler was used to transect its stalk. The polyp was retrieved via an endopouch placed through the intragastric laparoscopic port. We conclude that transgastric laparoscopy should be considered for the resection of a variety of pedunculated esophageal lesions when the use of standard endoscopic techniques is not possible.
