Standard laparoscopic versus single-incision laparoscopic colectomy for cancer: early results of a randomized prospective study.
BACKGROUND
Standard laparoscopic colectomy (SLC) for cancer is a safe, feasible, and oncologically effective procedure with better short-term and similar long-term results of open colectomy. Conversely, owing to technical difficulties in colonic resection and full mesenteric dissection, single-incision laparoscopic colectomy (SILC) has been considered unsuitable for oncologic purposes. We compared the technical feasibility and early clinical outcomes of SLC and SILC for cancer.


METHODS
In this prospective randomized clinical trial, 16 (50%) patients underwent SLC (10 left and 6 right) and 16 (50%) patients underwent SILC (8 left and 8 right).


RESULTS
Demographics, preoperative data, and characteristics of the tumor were similar. The mean number of resected lymph nodes was 16 ± 5 in the SLC and 18 ± 6 in the SILC group (P = NS). Surgical time was 124 ± 8 minutes and 147 ± 5 minutes, respectively (P = NS). Surgical mortality was nil and the major morbidity rate was 6.3% in both groups.


CONCLUSIONS
SILC for cancer is a technically feasible and safe oncologic procedure with short-term results similar to those obtained with a traditional laparoscopic approach.
