We report a case of gastrointestinal submucosal tumor with an intraluminal growth pattern resected by laparoscopic wedge resection. A 62-year-old man was admitted because of melena. Upper gastrointestinal endoscopy revealed gastrointestinal submucosal tumor with an intraluminal growth pattern just below the gastric junction, and the pathological diagnosis was GIST. A laparoscopic wedge resections(percutaneous endoscopic intragastric surgery)was performed by a single access port. After laparotomy 5 cm above the umbilicus, the anterior wall of the middle part of the stomach was incised and fixed to the skin, and the tumor was dissected with a linear stapler. The final pathology result showed a high risk GIST of 70×40 mm with 110 mitotic images/50 HPF, and the patient was treated with imatinib mesylate adjuvant chemotherapy. There were no complications, including postoperative transit disturbances, and there were no local or distant metastatic recurrences.
