[Laparoscopic partial gastrectomy for gastric submucosal tumor-indications and limitations of single-incision laparoscopic surgery].
Because gastric submucosal tumors can be treated by local resection without lymph-node dissection, laparoscopic local resection is widely used to manage relatively small tumors less than 5 cm in diameter. On the other hand, single-incision laparoscopic surgery (SILS) to perform laparoscopic cholecystectomy was feasible. SILS requires only a single incision in the umbilical region; it has better cosmetic outcomes than conventional laparoscopic surgery. The relative difficulty and ease of local gastric resection depends to a large part on tumor location and morphologic characteristics. Extraluminal submucosal tumor of the stomach can be locally resected by SILS using an automated suturing device regardless of tumor location. Intraluminal tumor located in the greater curvature of the gastric body can be treated by SILS, whereas intraluminal lesions located in the lesser curvature and near the gastric cardia or pylorus are difficult to manage by SILS. Laparoscopic and endoscopic cooperative surgery (LECS) is useful for resecting an appropriate amount of tissue at any site. In patients with lesions located near the gastric cardia or pylorus, closure with an automatic suture device may be difficult. Such patients should be switched to reduced-port surgery with a coaxial port, and hand-sewn closure is useful.
