In recent years, minimally invasive surgery has become the mainstream trend of modern surgery with the　rapiddevelopment of endoscopic and laparoscopic techniques. However, there are limitations when either technique is used　alone. The　laparoscopic and endoscopic cooperative surgery (LECS), which combines the advantages and makes up the　deficiencies of these two techniques, has expanded the application field of minimally invasive surgery. Laparoscopic wedgeresections are　increasingly applied for gastric stromal tumor. Base on clinical experience of 43 patients who underwent laparoscopic wedge resections for surgical treatment of gastric stromal tumor, we conclude that this procedure is feasible and safe.
