Application of laparoscopic techniques for resection of individual gastric submucosal tumors

Large gastric submucosal tumors should be excised to prevent ischemic mucosal ulceration of the overlying surface and central necrosis of the neoplasm, which may in turn lead to massive hemorrhage. Large tumors near the esophagocardiac junction or on the posterior wall are usually resected by an open procedure. We describe 2 cases of upper gastrointestinal tract bleeding owing to huge submucosal tumors in the posterior gastric high body treated by laparoscopic resection of the gastric tumors. These 2 patients recovered smoothly without major or minor complications. We emphasize that design of specific strategies for individual tumors is essential for the successful laparoscopic resection of tumors adjacent to the esophagocardiac junction and large tumors on the posterior wall.
