| アブストラクト | OBJECTIVE: To compare the risks of postendoscopy outcomes associated with warfarin with direct oral anticoagulants (DOACs), taking into account heparin bridging and various types of endoscopic procedures. DESIGN: Using the Japanese Diagnosis Procedure Combination database, we identified 16 977 patients who underwent 13 types of high-risk endoscopic procedures and took preoperative warfarin or DOACs from 2014 to 2015. One-to-one propensity score matching was performed to compare postendoscopy GI bleeding and thromboembolism between the warfarin and DOAC groups. RESULTS: In the propensity score-matched analysis involving 5046 pairs, the warfarin group had a significantly higher proportion of GI bleeding than the DOAC group (12.0% vs 9.9%; p=0.002). No significant difference was observed in thromboembolism (5.4% vs 4.7%) or in-hospital mortality (5.4% vs 4.7%). The risks of GI bleeding and thromboembolism were greater in patients treated with warfarin plus heparin bridging or DOACs plus bridging than in patients treated with DOACs alone. Compared with percutaneous endoscopic gastrostomy, patients who underwent endoscopic submucosal dissection, endoscopic mucosal resection and haemostatic procedures including endoscopic variceal ligation or endoscopic injection sclerotherapy were at the highest risk of GI bleeding among the 13 types of endoscopic procedures, whereas those who underwent lower polypectomy endoscopic sphincterotomy or endoscopic ultrasound-guided fine needle aspiration were at moderate risk. CONCLUSION: The risk of postendoscopy GI bleeding was higher in warfarin than DOAC users. Heparin bridging was associated with an increased risk of bleeding and did not prevent thromboembolism. The bleeding risk varied by the type of endoscopic procedure. |
