title: [Colorectal neoplasms. Treatment of obstruction with autoexpanding metal stents].
abstract: BACKGROUND
  Expandable metal stents can be used as a palliative or pre surgical method to decompress obstructing colonic carcinomas.
  
  
  OBJECTIVE
  To assess the effectiveness of these stents in the treatment of obstructive colonic carcinoma.
  
  
  METHODS
  Expandable metal stents were placed in nine patients with the diagnosis of colorectal carcinoma and with clinical and radiographic signs of intestinal obstruction. Stents were placed under fluoroscopic guidance in nine patients and with endoscopic help in 2. The indications were palliative treatment in 7 and pre surgical decompression in 2 patients.
  
  
  RESULTS
  Stent placement was successful in all patients. One patient presented a self limited rectal bleeding after the procedure. Obstruction was relieved in less than 24 hours after the procedure.
  
  
  CONCLUSIONS
  Expandable metal stent placement is an effective means of relieving intestinal obstruction caused by colorectal carcinoma.
