Method: Between 2012 and 2016, 18 consecutive patients with submucosal tumor of the stomach underwent surgery in our institute. Surgical approach for LECS was performed as following criteria: the longer diameter of the tumor was less than 5cm, no ulceration and no invasion for other organs. 

Results: LECS was performed for 5 cases, laparoscopic partial gastrectomy  (LPG) was for 4 cases and open partial gastrectomy (OPG) was for 7 cases. Patients undergoing LECS had significantly small tumor size compared with LPG and OPG cases (median 30 mm, 47.5 mm and 70 mm). For LECS cases, tumor pathology included GIST in 3 patients, schwannoma in one and adenoma in one. Four tumors were located in the body of stomach, one in the cardia. The mean operating time was 214.4 (156-248) minutes, median intraoperative blood loss was 0 (0-0) ml and median postoperative length of stay was 8 (7-9) days. In these items, there were no significant differences between three groups. There were no postoperative complications (Clavien-Dindo classification v2.0, Grade II or higher) in three groups. 

Conclusions: It is suggested that LECS is as feasible and safe procedure for gastric submucosal tumor as conventional methods.},
