title: Laparoscopic and endoscopic cooperative surgery for gastrointestinal stromal tumor with complete situs inversus: report of a case.
abstract: We herein report our experience of performing laparoscopic and endoscopic cooperative surgery for a gastrointestinal stromal tumor with complete situs inversus. A 78-year-old man was referred to our department for treatment of a gastric submucosal tumor. Based on chest X-ray and computed tomography (CT) findings, complete situs inversus was also diagnosed. Upper gastrointestinal endoscopy and imaging showed a 45-mm gastric submucosal tumor in the upper stomach near the esophagogastric junction. We performed local resection of the gastric submucosal tumor by laparoscopic and endoscopic cooperative surgery. Pathological examination revealed that the tumor was an intermediate-risk gastrointestinal stromal tumor, and the patient was discharged on postoperative day 12. The patient is still alive without recurrence or any complications 9 months after surgery.
