Conventional methods involving surgical staplers require relatively large lateral margins, which may cause deformity and postoperative dysfunction of the gastric remnant. In this study, we introduce a novel technique called laparoscopic submucosal dissection (LSD) in which the defects of the stomach are minimized and a microscopic negative margin is secured. Methods: The normal seromuscular layer of the gastric wall was dissected with a 5 mm lateral margin. Then, the submucosal tissue was divided carefully using a monopolar electrosurgical device with a curved spatula tip. Results: The operation time was 170 min, and the amount of bleeding was very small. We confirmed an intact pseudo-capsule and marginal subserosal or submucosal tissue of the tumor by histological analysis. The postoperative course was uneventful with no complications. Endoscopy showed minimal deformity of the gastric remnant. Conclusions: We think that LSD is a curative and less invasive treatment for GIST of the stomach. Further investigations are necessary to evaluate the oncological and functional outcomes of this procedure.展开更多
