Laparoscopy and endoscopy cooperative surgery(LECS)is a surgical procedure to avoid excessive resection of the gastrointestinal wall and preserve its function. For gastrointestinal stromal tumors(GIST)near the cardia and pylorus ring, the function of the cardia and pylorus can be preserved by minimum excision and hand-sewn suture closures. Here, we report a case successfully treated with inverted LECS for GIST near the pylorus ring. The patient was a 58-year-old male. Upper gastrointestinal endoscopy had revealed a 45 mm sized SMT near the pylorus ring. Biopsy by EUS-FNA indicated gastric GIST. The tumor was separated from the pylorus ring and inverted LECS was performed. The defect was closed with hand-sewn sutures, forming an L-shape. The postoperative course was good and he was discharged from hospital 10 days after surgery. It is considered that devising the direction of closure by means of the LECS procedure can preserve the pyloric function without passage obstruction or stasis, even for gastric GIST near the pylorus ring.
