Laparoscopic surgery has widely spread in the treatment of colorectal cancer. For colorectal cancers, many randomized controlled trials regarding short-term outcome demonstrate that laparoscopic surgery is feasible, safe and has many benefits including reduction in a perioperative mortality. In terms of long-term outcome, four randomized controlled trials insist that there are no differences in both laparoscopic and open surgeries proving oncologic safety and that the long-term outcome is at least not inferior to open resection. However, there are still more important issues including long-term oncological outcome for advanced colon cancer, costeffectiveness and the impact on quality of life of patients.
