Single-port laparoscopic surgery (SPLS)is more difficult than conventional multi-port laparoscopic surgery. There have been a limited number of reports of SPLS procedures in colorectal disease. We analyzed the feasibility of this procedure for colorectal cancers and to estimate its difficulty.
METHODS AND PROCEDURES:
We analyzed cancer cases retrospectively collected data from 220 consecutive patients who underwent single-port laparoscopic surgery at our institution. Patient and tumor characteristics, procedures of lymph node dissection, short term results of operation were analyzed.
Forty-three single-incision laparoscopic colectomies were performed (28 right colectomies, 3 transverse colic resections, 9 sigmoidectomies, and 3 anterior resection). No conversions to open resection occurred. An additional port was required in 3 patients. Mean incision length was 4.2 cm (range, 2.5-6) blood loss was 48g, and operative time was 145 minutes. Complications included 2 wound infection. Mean lymph node harvest was 15 (range, 10-27). In rectal resection, much technical difficulties were encountered compared than right colectomies.
Our data demonstrate that single-incision laparoscopic colectomies for colorectal cancers were safe and oncologically feasible in selected patients by experienced surgeons.
