title: Use of self-expanding metal stents to treat malignant colorectal obstruction in general endoscopic practice (with videos).
abstract: BACKGROUND
  Self-expanding metal stents (SEMS) are being increasingly used to solve malignant colorectal obstruction (MCRO). Patients can then either undergo scheduled surgery or have the stent left in place as a definitive palliative treatment. The majority of reports on the use of SEMS in MCRO come from single centers; therefore, its use in general endoscopic practice is not clearly known.
  
  
  OBJECTIVE
  To study the use of SEMS for MCRO in a wide endoscopic practice.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  A survey was carried out among endoscopists in 13 hospitals in Spain (6 tertiary referral centers and 7 community hospitals).
  
  
  METHODS
  Those who presented with MCRO.
  
  
  METHODS
  A total of 175 attempts to insert colorectal SEMS were made during a 12-month period (October 2003 to September 2004).
  
  
  METHODS
  Technical and clinical success and possible differences according to the type of hospital.
  
  
  RESULTS
  There was a mean of 1.2 attempts/mo per center (range, 2-0.5 attempts/mo per center). Insertion success was achieved in 162 (92.6%) and acceptable colonic decompression in 138 of 175 (78.8%) attempts and in 138 of 162 (85.1%) of successfully inserted stents. SEMS served as a bridge to scheduled surgery in 72 of 175 (41%) and as a palliative definitive treatment in 66 of 175 (37.7%). The major complication was perforation, which occurred in 7 of 175 occasions (4%) and led to death in 2 patients (1%). There were other less severe complications (25 [14%]). No significant differences in outcome of stent placement procedures were found between both categories of centers.
  
  
  CONCLUSIONS
  Retrospective study involving many centers and the possibility of bias for different assessments of outcomes.
  
  
  CONCLUSIONS
  In this study, success rates for SEMS placement and colonic decompression in MCRO were acceptable, without substantial differences according to the type of hospital. This procedure appeared to be feasible in general endoscopic practice.
