title: Intragastric surgery using laparoscopy and oral endoscopy for gastric submucosal tumors.
abstract: We review the techniques and outcomes of the intragastric resection for gastric submucosal tumors (GSTs) using laparoscope and oral endoscope. In the literature, the mean operation time, intraoperative blood loss, pathological size of the tumor and postoperative hospital stay were 134 min, minimal, 31 mm and 6.4 d, respectively. There were no particular perioperative complications during the follow-up period (mean: 121.3 mo). Intragastric surgery using laparoscopy and oral endoscopy can be considerably beneficial for patients with GSTs locating in the upper third of the stomach between 2-5 cm in diameter and < 8 cm(2) in cross-sectional area and located in the upper third of the stomach.
