title: Laparoscopic bowel resection in the setting of metastatic colorectal cancer.
abstract: BACKGROUND
  This study aimed to review the outcomes of laparoscopic colorectal resection for patients with stage IV colorectal cancer.
  
  
  METHODS
  From the prospectively collected database for patients who underwent surgery for colorectal cancer in our institution, those with stage IV colorectal cancer who underwent elective resection of tumor during the period from January 2000 to June 2006 were included. The outcomes of those with laparoscopic resection were reviewed and comparison was made between patients with laparoscopic and open resection.
  
  
  RESULTS
  A total of 200 patients (127 men) with median age of 69 years (range: 25-91 years) were included, and 77 underwent laparoscopic resection. Conversion was required in ten patients (13.0%) and all except one conversion were due to fixed or bulky tumors. There was no operative mortality in the laparoscopic group. The complication rate was 14% and the median postoperative hospital stay was 7 days. When patients with laparoscopic resection were compared with those with open operations, there was no difference in age, gender, comorbidity, or tumor size between the two groups. However, the complication rate was significantly lower in those with laparoscopic resection (14% versus 32%, P = 0.007) and the median hospital stay was significantly shorter (7 days versus 8 days, P = 0.005). The operative mortalities and the survivals were similar in the two groups.
  
  
  CONCLUSIONS
  Colorectal resection can be performed safely in patients with stage IV colorectal cancer. The operative outcomes in terms of complication rate and hospital stay compare favorably with patients with open resection.
