title: [Application of endoscopic full-thickness resection in the treatment of gastric tumors originated from the muscularis propria].
abstract: OBJECTIVE
  To evaluate the curative effect and safety of endoscopic full-thickness resection (EFR) in the treatment of gastric tumor originated from the muscularis propria.
  
  
  METHODS
  Clinical data were collected from 34 patients, who underwent EFR of gastric tumor originated from muscularis propria, to observe the resection rate and complications from November 2012 to August 2014.
  
  
  RESULTS
  Of the 34 patients, 15 were male, 19 were female, with the age of 38.3-70.6 (52.3±4.3) years old. The lesions of 25 patients located in the fundus of stomach and the rest was in the gastric body. EFR was successfully performed in the 34 patients with no need for surgery. The complete resection rate was 100%. Lesion diameter ranged from 1.0 to 5.0 (2.8±1.2) centimeters. The operation time was 50-100 (76.5±18.2) min. Patients with pneumoperitoneum were relieved after abdominal puncture exhaust, without post-operation bleeding and perforation. The hospitalization duration was 3-5 (3.6±0.8) days. Except 1 case, the remaining 33 cases were spindle cell tumors, consistent with the results of immunohistochemistry. The risk for two lesions with 4.5 cm and 5.0 cm was moderate. The risk of invasion was low or very low in the remaining 31 cases. Among them, 2 stromal tumors near the cardia showed a differentiation tendency toward smooth muscle. No lesion residual or recurrence happened during the follow-up period (range 5-23 months) in 34 cases.
  
  
  CONCLUSIONS
  EFR is a safe and effective method for gastric tumor originated from muscularis propria.
