title: [Clinical application of self-made drainage tube with balloon for iatrogenic colonic perforation].
abstract: OBJECTIVE
  To investigate the clinical efficacy of colonic bypass drainage by self-made drainage tube with balloon for iatrogenic colonic perforation.
  
  
  METHODS
  A retrospective analysis of 8 patients with iatrogenic colonic perforations from January 2009 to March 2011 was performed. Self-made drainage tubes with balloon were placed in the bowel lumen endoscopically after perforations were closed with endoclips or endoloops under endoscope. The inflatable balloon at the front-end of the tube was fixed at the mouth side of colonic perforation to achieve continuous drainage of stool and intestinal juice.
  
  
  RESULTS
  Endoscopic bypass continuous drainage by using self-made drainage tube with balloon was successfully carried out in all the 8 patients. All the perforations healed and no surgical intervention required. Bypass drainage continued for 3-10 days(mean 7.6 days). One patient received colonoscopy 3 days after the procedure, and displacement of the drainage tube was noticed requiring endoscopic adjustment. All the drainage tubes were removed uneventfully, and no ulceration or perforation occurred at balloon fixed site after removal. After follow up ranging from 12 to 36 months, no chronic fistula, adhesive obstruction, or abdominal infection occurred.
  
  
  CONCLUSIONS
  Colonic bypass drainage by self-made drainage tube with balloon for iatrogenic colonic perforation is simple, feasible, safe and reliable.
