Abstract:
Laparoscopy and endoscopy cooperative surgery(LECS)is an excellent surgical procedure to avoid excessive resection of the gastrointestinal wall and maintain its functions. However, LECS for large gastrointestinal stromal tumor(GIST)of> 50mm and/or ulcerative GIST are not recommended because of the oncological risk of peritoneal dissemination. Here, we report a case successfully treated with LECS-assisted open partial gastrectomy for a high-risk GIST with ulceration near the esophago-gastric junction.
