title: Single incision vs conventional laparoscopic anterior resection for sigmoid colon cancer: a case-matched study.
abstract: BACKGROUND
  The purpose of the study was to evaluate the safety and effects of single-incision laparoscopic anterior resection (SILAR) for sigmoid colon cancer by comparing it with conventional laparoscopic anterior resection (CLAR).
  
  
  METHODS
  Twenty-four patients who underwent SILAR between April 2010 and July 2011 were case matched 1:2 with patients who underwent CLAR, with respect to age, sex, body mass index, tumor location, and history of abdominal surgery.
  
  
  RESULTS
  Two patients in the SILAR group and 1 patient in the CLAR group experienced anastomotic leakage. The operative time was longer in the SILAR group than in the CLAR group (251 ± 50 vs 237 ± 49 minutes; P = .253). The number of harvested lymph nodes (19.6 ± 10.7 vs 20.8 ± 7.7; P = .630) was not different. The postoperative hospital stay was shorter in the SILAR group (7.1 ± 3.4 days) than in the CLAR group (8.1 ± 3.5 days) (P = .234).
  
  
  CONCLUSIONS
  On the basis of the early outcomes, we conclude that SILAR is feasible and safe. Moreover, the adequate lymph node harvest and free margins support the use of this procedure.
