PURPOSE: The aim of this retrospective study was to evaluate the feasibility of single incision laparoscopic surgery (SILS), and to compare the short-term surgical outcomes with those of conventional laparoscopic surgery for colorectal cancer. METHODS: Forty-four patients who underwent SILS were compared with 263 patients who underwent conventional laparoscopic surgery for colorectal adenocarcinoma between November 2011 and September 2012. RESULTS: In the SILS group, eleven cases (25.0%) of right hemicolectomy, 15 (34.1%) anterior resections, and 18 (40.9%) low anterior resections were performed. Additional ports were required in 10 rectal patients during SILS operation. In the 32 patients with rectosigmoid and rectal cancer in the SILS group, patients with mid and lower rectal cancers had a tendency to require a longer operation time (168.2 minutes vs. 223.8 minutes, P = 0.002), additional ports or multiport conversion (P = 0.007), than those with rectosigmoid and upper rectal cancer. Both SILS and conventional groups had similar perioperative outcomes. Operation time was longer in the SILS group than in the conventional laparoscopic surgery group (185.0 minutes vs. 139.2 minutes, P < 0.001). More diverting stoma were performed in the SILS group (64.7% vs. 24.2%, P = 0.011). Multivariate analysis showed that tumor location in the rectum (95% confidence interval [CI], 1.858-10.560; P = 0.001), SILS (95% CI, 3.450-20.233; P < 0.001), diverting stoma (95% CI, 1.606-9.288; P = 0.003), and transfusion (95% CI, 1.092-7.854; P = 0.033) were independent risk factors for long operation time (>180 minutes). CONCLUSION: SILS is a feasible, not inferior treatment option for colorectal cancer, and appears to have similar results as standard conventional multiport laparoscopic colectomy, despite the longer operative time.
