title: Preoperative intestinal stent decompression with primary laparoscopic surgery to treat left-sided colorectal cancer with obstruction: a report of 21 cases.
abstract: OBJECTIVE
  This work aimed to study the safety and efficacy of preoperative intestinal stent decompression combined with laparoscopic surgery to treat left-sided colorectal cancer with obstruction (LCCO).
  
  
  METHODS
  Retrospective analysis was conducted on data obtained from 21 LCCO patients admitted to The First Affiliated Hospital of Zhejiang Chinese Medicine University during March 2008 and December 2011. To remove the intestinal obstruction, preoperative intestinal stent placement under colonoscopic guidance was performed. Approximately 7 to 10 days after the operation, laparoscopic radical surgery of colorectal cancer was conducted.
  
  
  RESULTS
  Among the 21 cases studied, laparoscopic surgery was successful in 20 patients. Emergent laparotomy was conducted in one patient because of tumor invasion in the ureter. The duration of the operation ranged from 180 to 320 min, and the average time was 220 min. The recovery time for bowel function ranged from 2 to 5 days with an average time of 3 days. Postoperative infection of the incision occurred in one case. No anastomotic leakage was observed in any of the cases.
  
  
  CONCLUSIONS
  Preoperative intestinal stent decompression, combined with primary stage laparoscopic surgery, is a safe and effective method for the treatment of LCCO.
