Endoscopic resection of an extraluminal subepithelial tumor located on the anastomosis of a previous laparoscopic fundectomy

Abstract Text A 58 years old patient presented with a 3 cm subepithelial lesion located at the antastomotic line in the fundus. The patient has undegone a laparoscopic fundus resection of a 5 cm gastrointestinal tumor (GIST) four years ago. The tumor was located extraluminally and wasn't visible in endoscopy. We marked the location of the tumor and formed a submucosal tunnel proximal in the esophagus till we reached the anatostomosis. We removed through the tunnel dozens of surgical staplers before we could localize the tumor. The tumor was then detached and succesfully removed. It proved out, it was a recurrence of the previous GIST. To our knowledge this is the first case of a complete endoscopic removal of a GIST recurrence on the surgical site at the gastric fundus [1].
