[Investigation of the Short-Term Outcome of Perioperative Heparinization in Laparoscopic Surgery for Colorectal Cancer].

In aging society, the number of colorectal cancer patients who take antithrombotic drugs is increasing. However, there are not established guidelines for perioperative management for antithrombotic drugs in laparoscopic surgery. Here, we investigated the clinical outcomes of antithrombotic drugs withdrawal and perioperative heparinization in laparoscopic surgery for colorectal cancer patients taking antithrombotic drugs. From January 2015 to December 2017 in our center, patients who took antithrombotic drugs and underwent laparoscopic surgery for colorectal cancer were reviewed retrospectively. The association between postoperative complications and heparinizations was analyzed. Among 79 patients taking antithrombotic drugs, heparinization was performed in 40 patients(50.6%). The total length of hospital stay in heparinization group was 21 days and significantly longer than 13 days in the non-heparinization group. There were no significant differences in the operation time, intraoperative blood loss, and postoperative complications between the 2 groups. The antithrombotic drugs withdrawal and perioperative heparinization were suggested to be safe and feasible in laparoscopic surgery for patients with colorectal cancer.
