Associations between antithrombotic therapy and the risk of perioperative complications among patients undergoing laparoscopic gastrectomy.

ABSTRACT

BACKGROUND: The aim of this study was to identify factors associated with perioperative morbidity among patients who underwent laparoscopic gastrectomy while receiving antithrombotic therapy (ATT). PATIENTS AND METHOD: This retrospective cohort study included 46 patients (14 females and 32 males) who underwent laparoscopic gastrectomy, including 12 (26.1 %) who received perioperative ATT, between January 2012 and November 2015 in our institution. Among patients receiving only aspirin as antiplatelet therapy, none were on anticoagulation therapy. All patients took aspirin as antiplatelet therapy for cardiac indications. The clinical findings and surgical outcomes of patients who did (ATT group) and did not (control group) receive ATT were compared. RESULTS: The intraoperative mortality was 0 % for both groups. There was no significant difference in the incidence of postoperative morbidity by univariate analysis between the control and ATT groups (8.8 vs. 8.3 %, p = 0.39). CONCLUSION: The risk of postoperative morbidity of laparoscopic gastrectomy can be equivalent between the ATT and non-ATT (control) groups.
