Single incision vs conventional laparoscopic anterior resection for sigmoid colon cancer: A case-matched study

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.
