Single Surgical Approach for Gastric Gastrointestinal Stromal Tumor and Cholecystolitiasis by Laparoscopic Procedure

Abstract
Introduction: Gastrointestinal stromal tumor (GIST) is a rare neoplasm representing 80% of gastrointestinal neoplasms. Laparoscopic resection is only recommended for GIST less than 2 cm and 5 cm for laparoscopic wedge resection. Thus, a large GIST is recommended to complete resection through laparotomy. A large GIST of the gastric fundus can be found in patients, which coincides with an upper right abdominal quadrant pain caused by cholecystolithiasis. A suggested laparotomy for tumor resection and cholecystectomy may result in poor recovery in the postoperative period. Therefore, one approach surgery with minimally invasive laparoscopic partial gastrectomy using Endoflex stapler and cholecystectomy was performed to achieve the optimal outcome. Case Presentation: A 43-year-old male had a major complaint of hematemesis and melena for one month and colicky pain in the right upper quadrant of the abdomen with increased intensity in the last two months. Contrast-enhanced abdominal MSCT revealed a solid 4.6 x 4 x 5.6 cm exophytic mass on the gastric fundus, added with 0.5 cm gall bladder stone. Laparoscopic partial gastrectomy and cholecystectomy were performed in a single minimal invasive surgical procedure. The post-operative period was uneventful. The patient experienced minimum pain, early mobilization, and better diet tolerance. He was discharged on day four after the surgery. Besides, the histopathologic result revealed a malignant mesenchymal tumor according to GIST with a tumor-free margin of resection. Conclusions: Single approach surgery with minimal laparoscopic partial gastrectomy and cholecystectomy has provided optimal outcomes for patients with large GIST and cholecystolithiasis.
