Background and purpose: Thromboprophylaxis is recommended for preventing postoperative venous thromboembolism (VTE) after abdominal surgery; however, its use after major hepatobiliary-pancreatic surgery is typically avoided as it increases the risk of bleeding. We conducted this study to evaluate the safety of thromboprophylaxis after major hepatobiliary-pancreatic surgery. Methods: We analyzed the rates of postoperative bleeding, VTE, morbidity, and prolonged hospital stay in 349 patients who underwent major hepatobiliary-pancreatic surgery, such as pancreaticoduodenectomy, hemihepatectomy or greater, and hepatopancreaticoduodenectomy. Results: Chemical thromboprophylaxis was associated with significantly increased rates and risks of overall bleeding events vs. no chemical thromboprophylaxis (26.6 vs. 8.5 %, respectively). The rate of minor hemorrhage was significantly higher in patients who received chemical thromboprophylaxis (21.7 vs. 3.5 %); however, there were no differences in the rate of major hemorrhage requiring blood transfusion or hemostatic intervention between the groups (4.8 vs. 4.9 %). The postoperative VTE rate was also significantly decreased by chemical thromboprophylaxis (2.9 vs. 7.7 %). However, chemical thromboprophylaxis did not affect the rate of SSI, severe morbidity, or duration of the postoperative hospital stay. Conclusion: We consider that chemical thromboprophylaxis is beneficial and can be safely used even after major hepatobiliary-pancreatic surgery.
