Abstract

Purpose: The use of antiplatelet and/or anticoagulant therapies has become common. In rare cases, these therapies may increase the risk of dangerous postoperative bleeding. We investigated the association of antiplatelets and/or anticoagulants with postoperative major bleeding risk in laparoscopic gastric cancer surgery.
Methods: We retrospectively enrolled 3,663 gastric cancer patients (antiplatelet/anticoagulant group, 518; control group, 3,145) who had undergone laparoscopic surgery between January 2012 and December 2017. To minimize selection bias, 508 patients in each group were matched using propensity score matching (PSM) method. The primary outcome was postoperative major bleeding. Secondary outcomes were intraoperative, postoperative transfusion and early complications.
Results: After PSM, postoperative major bleeding occurred in 10 (2.0%) and 3 cases (0.6%) in the antiplatelets/ anticoagulants and control groups, respectively (P = 0.090). Intraoperative and postoperative transfusions were not significantly different between 2 groups (2.4% vs. 1.4%, P = 0.355 and 5.5% vs. 4.3%, P = 0.469). Early complications developed in 58 (11.4%) and 43 patients (8.5%) in the antiplatelets/anticoagulants and control groups, respectively (P = 0.142). The mean amounts of intraoperative and postoperative transfusions were not significantly different between the groups (366.67 ± 238.68 mL vs. 371.43 ± 138.01 mL, P = 0.962; 728.57 ± 642.25 mL vs. 508.09 ± 468.95 mL, P = 0.185). In multivariable analysis, male (P = 0.008) and advanced stage (III, IV) (P = 0.024) were independent significant risk factors for postoperative major bleeding.
Conclusion: Preoperative antiplatelets and/or anticoagulants administration did not significantly increase the risk of postoperative major bleeding after laparoscopic gastric cancer surgery.
