Short-term outcomes following laparoscopic resection for colon cancer

Laparoscopic resection for colon cancer has been proven to have a similar oncological efficacy compared to open resection. Despite this, it is performed by a minority of colorectal surgeons. The aim of our study was to evaluate the short-term clinical, oncological and survival outcomes in all patients undergoing laparoscopic resection for colon cancer.

From July 2005 to December 2008, 202 consecutive patients underwent laparoscopic resection for colon cancer. Surgery was analysed on an intention to treat basis. The mean follow-up was 24.3 months.

Two hundred twenty-two patients underwent resection for colon cancer. Two hundred two underwent laparoscopic resection (91%). One hundred sixteen were male patients. Mean age was 65.9 years (range = 24-91). The median length of stay was 6.6 days (mean = 7.1 days). One hundred eighty-eight of 202 (93.1%) were completed laparoscopically. Fourteen (6.9%) were converted. The overall morbidity rate was 15.8%. There were three clinically apparent anastomotic leaks. The 30-day mortality was 1 (0.5%). The mean nodal yield was 13.4 (range = 8-37) nodes. There were no positive margins detected. Overall survival in laparoscopically treated colon cancer was 88.1%. In those patients with non-metastatic disease, the overall survival was 90.7% (165/182).

Laparoscopic resection for colon cancer is achievable in 85% (188/222) of patients. This facilitates adequate oncological clearance. It is associated with a low morbidity rate and favourable short-term survival outcomes. This data reflects the potential outcomes dedicated MIS colorectal units will have to offer colon cancer patients once laparoscopic colorectal surgery becomes the de facto surgical approach.
