Comparison of Postoperative Outcomes Between Laparoscopic and Open Surgery for Colorectal Cancer

Abstract

Background/aim: To determine the superiority of the laparoscopic vs. open technique for colorectal cancer surgery.

Patients and methods: We performed a retrospective analysis of consecutive patients who underwent curative surgery by laparoscopic colectomy (LC) or open colectomy (OC) for colon cancer. The patients were classified into two groups: as LC group and OC group. We retrospectively assessed clinical characteristics, intraoperative and postoperative outcomes and long-term outcomes between the two groups by univariate analysis.

Results: The LC group had significantly less intraoperative blood loss, complications, and shorter post-operative hospital stay than the OC group. The overall survival of Stage II in the LC group is significantly longer than the OC group. DFS of Stage III in the LC group was significantly longer than the OC group.

Conclusion: LC showed more favorable results in both short-term and long-term outcomes than OC.
