[LECS-Assisted Open Partial Gastrectomy for an Ulcerative GIST in an Elderly Patient].

Laparoscopy and endoscopy cooperative surgery(LECS)is an excellent surgical procedure that prevents excessive resection of the gastrointestinal wall and maintains gastrointestinal functions. However, LECS is not recommended for large gastrointestinal stromal tumor(GIST)sized more than 5 cm and/or ulcerative GIST because of the oncological risk of peritoneal dissemination. Here, we report the case of an elderly patient who was successfully treated with LECS-assisted open partial gastrectomy for an ulcerative GIST near the esophagogastric junction.
