Single port laparoscopic surgery remains a novel technique in the field of colorectal surgery. Several small series have examined its safety and feasibility for colorectal surgery. Our aim was to analyze our entire experience and short-term outcomes with single port laparoscopic surgery for colorectal cancer since its introduction at our institution. We assert that this approach is feasible and safe for the patients with colorectal cancer.

Material and Methods:
This is a retrospective analysis of prospectively gathered data for all patients who underwent single port laparoscopic colorectal resection with the use of standard laparoscopic instrumentation between April 2010 and September 2012.
Clinical, operative and pathologic factors were reviewed and analyzed.

Fifty patients underwent single port laparoscopic colorectal surgery during the study period. The locations of tumor were 25 right-sided colon, 20 left-sided colon and 5 rectal cancers. The procedures were performed successfully in all cases. Rectal cancers needed one or two additional ports. Mean age was 69 years, and 45% of the patients were men, and the median body mass index was 22 ( range, 15-31) kg/m2. Mean and median length of skin incision was 3.3 and 3(1.5-6) cm. Median operative duration was 222 (113-366) minutes. Mean and median blood loss was 28 and 10 mL. Median postoperative stay was 7 (4-25) days. Median harvest lymph node number was 17 (3-46).Surgical margins were negative in all cases. There were no intraoperative complications. Morbidity was 8%. There was no mortality postoperatively in this series.

In early series of high selected patients, this technique appears to be fesible and safe and produce an excellent cosmetic result when performed by surgeons skilled in laparoscopic colorectal surgery. These findings support the use of a single port approach for patients requiring colorectal surgery.
