Purpose Laparoscopy is the approach of choice for the majority of colorectal disorders that require a minimally invasive abdominal operation. As the emphasis on minimizing the technique continues, natural orifice surgery is quickly evolving. The authors utilized an embryologic natural orifice, the umbilicus, as sole access to the abdomen to perform a colorectal procedure. Herein, we present our initial experience of single-port laparoscopic colorectal surgery using a Uni-XÔ Single-Port Access Laparoscopic System (Pnavel Systems, Morganville, New Jersey, USA) with a multi-channel cannula and specially designed curved laparoscopic instrumentation.Method The abdomen was approached through a 3.5 cm incision via the umbilicus and a single-port access device was utilized to perform a right hemicolectomy on a patient with an unresectable caecal polyp and a body mass index of 35. Ligation of the ileocolic artery was done with a LigaSure DeviceÔ (Covidien Ltd, Norwalk, Connecticut, USA), and was followed by colonic mobilization, extraction and extracorporeal ileocolic anastomosis.Results The total operative time was 115 min with minimal blood loss. Hospital stay was 4 days with no undue sequelae.Conclusion Single-port laparoscopic surgery may allow common colorectal laparoscopic operations to be performed entirely through the patient's umbilicus and enable an essentially scarless procedure. Additional experience and continued investigation are warranted.

IPAA is an excellent option for patients with MUC, IC, FAP, and select patients with Crohn's disease.

T-C is an option for patients with complex anorectal conditions that might otherwise require permanent diversion. Functional outcomes are comparable to those of CAA.

These results question the routine use of adjuvant chemotherapy for patients with rectal cancer who undergo curative surgery who have been rendered node-negative by neoadjuvant chemoradiation.
