title: [Colorectal stents: efficacy and complications in our center].
abstract: BACKGROUND
  in emergency surgery, colorectal mortality is very high compared with elective surgery. An alternative is placement of endoscopic stents to correct the bowel obstruction and then allow elective surgery. Moreover, it is possible to use stents in the palliative treatment of patients at high surgical risk or with unresecable tumors. The aim of this study is to evaluate the rates of technical and clinical success and complications of colorectal stent placement over the past 5 years.
  
  
  METHODS
  retrospective study of 33 patients in which stents were placed since 2006 to 2011. Variables were analyzed: 1) the indication (palliation or "bridge to surgery"), 2) rates of technical success and clinical success, and 3) complications (perforation, migration, bleeding, and reocclusion).
  
  
  RESULTS
  in 24 patients the prosthesis was placed as a palliative treatment (72.7%) and in 9 cases as a "bridge to surgery". The technical success rate was 87.87% and 82.14% clinical success. There were five cases of bowel perforation with high pneumoperitoneum and a case of microperforation (18.1%). Five patients had reocclusion (17.2%); there were 3 and 4 with bleeding and migration. Three patients died within 24 hours after endoscopic treatment. In 9 cases of "bridge to surgery," technical success was 100% and 77% clinical success. One patient required emergency surgery due to migration of the prosthesis and reocclusion and another colonic perforation.
  
  
  CONCLUSIONS
  endoscopic treatment is a good option as a transitional step to elective surgery or palliative treatment. But serious complications such as perforation or reocclusion should be considered.
