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 cm2 in cross-sectional area and located in the upper third of the stomach.
Core tip: The laparoscopic approach for gastric submucosal tumors (GSTs) depends on the characteristics of the submucosal tumors including its location or size. In particular, GSTs located close to the esophagogastric junction or pyloric ring cannot be easily applied the laparoscopic local resection. Therefore, the intragastric approach is adopted for those tumors. This review evaluates the technique and outcomes of the intragastric resection for GSTs using laparoscopy and oral endoscopy. Intragastric surgery using laparoscopy and oral endoscopy can be considerably beneficial for patients with GSTs less than 5 cm in diameter and locating in the upper third of the stomach.
