title: The role of colorectal stent placement in the management of acute malignant obstruction.
abstract: BACKGROUND
  In recent decades, the use of colorectal stents for palliation or as a bridge to surgery in acute malignant colorectal obstruction has increased. We aimed to evaluate the technical and clinical efficacy, safety and clinical outcomes of endoscopic stenting for the relief of acute colorectal obstruction secondary to cancer.
  
  
  METHODS
  From March 2006 to December 2012, among 100 patients with acute malignant colorectal obstruction, stenting procedures were performed on 42 patients for relief of obstruction. Uncovered self-expanding metal stents (SEMS) were placed endoscopically under fluoroscopic guidance in all patients. Using the patient database, a review was conducted to determine the effectiveness of the procedure and the short- and long-term complications.
  
  
  RESULTS
  Stent placement was technically successful in 39/42 (92.8%) and clinically successful in 38/42 (90.4%) patients. Sixteen patients later underwent an elective surgical resection, and in 26 patients with metastatic disease or comorbidity, stent placement was palliative. Complications occurred in 10 (23.8%) patients, and the most common was tenesmus (n=3). Migration, bleeding, and recto-sigmoid perforation occurred in two patients each. Stent obstruction due to fecal impaction was seen in one case.
  
  
  CONCLUSIONS
  Stent placement for colorectal obstruction is an effective and relatively safe procedure, with minor complications. It not only allows subsequent elective resection, but is also definitive for palliative treatment in patients with obstructive colorectal cancer.
