title: [Endoscopic self-expanded metal stent for gastric outlet obstruction:a ten-year experience].
abstract: OBJECTIVE
  To evaluate the efficacy of endoscopic self-expanded metal stent for the treatment of gastric outlet obstruction.
  
  
  METHODS
  Fifty-six cases of gastric outlet obstruction, collected from March 1999 to January 2008, were treated by endoscopic self-expanded metal stents. The success rate, complication rate and survival were evaluated.
  
  
  RESULTS
  Among the 56 cases, the male to female ratio was 33 to 23, and the average age was [65+/-14 (24-86)] years. Seventeen cases were gastric cancer, 4 duodenal carcinoma, 7 peri-ampulla carcinoma, 13 metastasis cancer and 15 presented recurrence after operations. The success rate of stent implantation was 98.2% (55/56). Forty-nine cases (87.5%) could eat liquid food 1-3 days after operations and eat semifluid food 4-9 days later. Forty-two cases (76.4%)could eat normal food after 10-16 days. The main complications included 14.5% of cases with pain, 1.8% with stent shift, 25.5% with bleeding and no one with perforation. Until January 20, 2008, 53 cases (96.4%) had been followed up. The mean survival time was [139+/-15 (14-332)] days, and the median survival time was 135 days. The re-stenosis rate was 5.7%, including 3 cases, happened in 143, 158 and 190 days after the operations respectively, and was successfully treated by second stent implantation.
  
  
  CONCLUSIONS
  Endoscopic implantation of self-expanded metal stent is a micro-invasive, safe, effective method for the treatment of gastric outlet obstruction.
