[Laparoscopic Local Resection for a Gastric GIST with Ulcer Locating Near to the Esophagogastric Junction - A Case Report].

A 39-year-old woman visited our hospital because of epigastric pain. Gastrointestinal endoscopy revealed a gastric submucosal tumor, 30mm in size, with ulcer locating near to the esophagogastric junction, and it was diagnosed with GIST by the endoscopic ultrasonography-guided fine needle aspiration. Then, she underwent laparoscopic surgery for the removal of gastric GIST. After peeling around the upper stomach, the local resection of the stomach was performed with linear staplers in the minor axis direction under the vision of the endoscope and laparoscope. Histopathological examinations confirmed that the tumor was GIST with an intermediate risk, and all surgical margins were free of GIST cells. Local resection with the laparoscopy endoscopy cooperative surgery(LECS)technique is a very useful way of the removal of gastric GISTs locating near to the esophagogastric junction in terms of the remnant gastric functions. Meanwhile, because the standard LECS requires the opening of the gastric lumen, there remains concerns about the intraperitoneal tumor dissemination for the gastric GIST with ulcer. We herein reported a case of laparoscopic local resection for a gastric GIST with ulcer locating near to the esophagogastric junction without gastric opening.
