EUS-guided gastroenterostomy assisted by extrinsic abdominal compression to treat gastric obstruction after surgical resection of a GI stromal tumor

Abstract

EUS-guided gastroenterostomy is increasingly used to treat gastric outlet obstruction after surgery such as a Whipple procedure. Postoperative stenosis of the gastric lumen is a described adverse event after laparoscopic wedge resection of submucosal tumors located on the lesser curvature. We describe a case of EUS-guided gastroenterostomy facilitated by extrinsic abdominal compression to treat gastric obstruction resulting from a laparoscopic wedge resection of a gastrointestinal stromal tumor.
