Risk Factors for Delayed Bleeding after Therapeutic Gastrointestinal Endoscopy in Patients Receiving Oral Anticoagulants: A Multicenter Retrospective Study.
Delayed bleeding is among the adverse events associated with therapeutic gastrointestinal endoscopy. The aim of this study was to evaluate risk factors for delayed bleeding after gastrointestinal endoscopic resection in patients receiving oral anticoagulants as well as to compare the rates of occurrence of delayed bleeding between the oral anticoagulants used. ⋯ This study identified continued anticoagulant therapy, anticoagulant withdrawal with HBT, anticoagulant therapy combined with 1 antiplatelet drug, and ESD as risk factors for delayed bleeding after therapeutic endoscopy in patients receiving oral anticoagulants. Delayed bleeding rates were not significantly different between those receiving DOACs and warfarin. It was also suggested that the occurrence of delayed bleeding may vary between different DOACs and that oral anticoagulant withdrawal should be minimized during therapeutic gastrointestinal endoscopy, given the thromboembolic risk involved.
