Objective To compare clinical outcomes between laparoscopic (LAP) and open surgery for non-metastatic colon cancer of T4a stage.Methods We retrospectively analyzed clinical data of non-metastatic colon cancer patients of T4a stage with confirmed pathological results who underwent curative resection in Peking Union Medical College Hospital between January 2011 and December 2017. These patients were allocated into LAP group (n=107, underwent laparoscopic radical operation) and open group (n=52, underwent open surgery).Results There were no significant difference in operating time, number of lymph nodes harvested, number of positive lymph nodes, incidence of complications within 30 days, and Clavien-Dindo grading between the LAP group and open group (P>0.05), but intraoperative blood loss, postoperative exhaust time, and postoperative hospital stay in the LAP group were less than (shorter than) those of the open group (P<0.05).Conclusion Laparoscopic approach for non-metastatic colon cancer of T4a stage is safe and feasible, and it has advantages including less intraoperative blood loss, faster recovery, and shorter hospital stay.
