Perioperative Antithrombotic Management During Gastroenterological Surgery in Patients With Thromboembolic Risks: Current Status and Future Prospects.

Abstract

Antiplatelet medicines and anticoagulants are two types of antithrombotic pharmaceuticals, with anticoagulants including warfarin and direct oral anticoagulants (DOACs). During the perioperative phase, patients receiving antithrombotic therapy must balance two risks: bleeding and thromboembolism. To date, there are no defined recommendations for antithrombotic drug management in gastroenterological (GE) surgery, and the management strategy varies greatly between hospitals. The perioperative treatment of antithrombotic medications should be centralized according to the mechanism of each drug, and a suitable management strategy should be established. The proposed perioperative management for patients undergoing antithrombotic therapy is as follows: (1) in the case of antiplatelet medication, aspirin monotherapy is continued; (2) for patients on warfarin, it is substituted by DOAC bridging (preferred) or heparin bridging; and (3) in the case of DOACs, the short-term withdrawal of DOACs (typically 1-2 days) without heparin bridging is indicated. In the current review, the current state and future prospects of perioperative antithrombotic medication treatment during gastroenterological surgery are discussed.
