Background: Laparoscopic wedge resection (LWR) is widely performed for managing gastric submucosal tumors (SMTs). Despite the development of novel procedures such as laparoscopy–endoscopy cooperative surgery (LECS) and nonexposed endoscopic wall-inversion surgery (NEWS), the most appropriate surgical intervention for gastric SMTs remains unclear. Methods: We retrospectively reviewed patient characteristics, surgical outcomes, postoperative courses, results of histopathological examinations, and surgical costs of 71 consecutive patients who underwent LWR, LECS, or NEWS for gastric SMTs from January 2010 to June 2016 in our institute. Results: LWR, LECS, and NEWS were performed in 31, 14, and 26 cases, respectively. Patient backgrounds were comparable between groups. LWR was not performed for esophagogastric (E–G) junction tumors to avoid postoperative stricture, and LECS was not performed for ulcerated tumors to prevent tumor dissemination. NEWS was considered for tumors smaller than 3 cm for transoral extraction. Resected specimen area of the LWR group was significantly larger than that of the other groups. Further, the LWR group had a significantly higher complication rate. Compared to the LECS group, postoperative serum C-reactive protein level was significantly lower and postoperative hospitalization was significantly shorter in the NEWS group. Also, operation costs were significantly lower in the NEWS group. Conclusions: The surgical procedure for gastric SMTs must be carefully chosen according to tumor size, location, and presence or absence of ulceration. For selected patients, NEWS is suggested to be an appropriate option for the treatment of gastric SMTs.
