Introduction: Single-incision laparoscopic surgery (SILS) has recently been developed with the aim to further reduce the invasiveness of conventional laparoscopy. In the present study, our initial experiences with SILS for colon cancer are reviewed, and its outcomes are evaluated.

Methods: Our initial experience of SILS for colon cancer is presented. 117 patients (47 women) were treated with the SILS procedure between August 2010 and August 2012. The abdomen was approached through a 2.5cm transumbilical incision. Almost all the procedures were performed with standard laparoscopic instruments, and the operative procedures were similar to those employed in the standard laparoscopic colectomy.

Results: Six patients were converted to laparotomy, and three patients required an additional port insertion. The other 108 patients (92%) underwent a curative resection of the colon cancer. Of these 108 patients, 36 patients underwent right hemicolectomy, 30 underwent ileo-colectomy, 24 underwent sigmoidectomy, 10 underwent partial resection of the descending colon, 6 underwent left hemicolectomy, and partial resection of the transverse colon with SILS procedure. The mean skin incision was 2.84cm. The mean operative time and blood loss were 192.3 min and 67.7 mL, respectively. The mean number of harvested lymph nodes was 25.0. Intra- or postoperative complications occurred in six patients (2; surgical site infection, 2; incisional hernia, 1; anastomotic leakage, 1; small bowel obstruction). The patients were discharged after a mean period of 11.4 postoperative days.

Conclusions: Our initial experiences suggested that SILC is feasible and safe for colorectal cancer patients. However, further studies need to be undertaken to prove that it has non-cosmetic advantages over conventional laparoscopic colectomy.
