Materials and Methods: We retrospectively analyzed 69 patients with gastric SETs originating from the MP at our hospital between September 2009 and July 2016. The data from each patient were reviewed, including patient information, tumor characteristics, procedure-related data, and recurrence rates. Results: Successful complete resection by EFR was achieved in 69 cases. The complete resection rate was 100%, and the mean resected tumor size was 2.25±1.40 (range, 0.6 to 6) cm. No residual tumor recurrence was detected during the follow-up period in 57 patients. The other 12 patients were lost to follow-up. Conclusions: EFR seems to be a safe and effective technique for the treatment of patients with gastric SETs originating from the MP.
