Popis: Background Post-hemorrhoidectomy bleeding is a serious complication after hemorrhoidectomy. In the setting of a new wave of anticoagulants, we aimed to investigate the relationship of post-operative anticoagulation timing and delayed bleeding. Methods We performed a retrospective analysis of all patients undergoing hemorrhoidectomy at a single institution over a 10-year period. Fisher’s exact and Wilcoxon Rank Sum tests were utilized to test for association between delayed bleeding and anticoagulation use. Results Between January 2011 and October 2020, 1469 hemorrhoidectomies were performed. A total of 216 (14.7%) were taking platelet inhibitors and 56 (3.8%) other anticoagulants. Delayed bleeding occurred in 5.2% (n = 76) of which 47% (n = 36) required operative intervention. Mean time to bleeding was 8.7 days (SD ±5.9). Time to bleeding was longer in those taking antiplatelet inhibitors vs. non-platelet inhibitors vs. none (11 vs. 8 vs. 7 days, P = .05). Among anticoagulants (n = 56), novel oral anticoagulants were more common than warfarin (57% vs 43%) and had a nonsignificant increase in delayed bleeding (31% vs 16%, P = .21). Later restart (>3 days) of novel anticoagulants after surgery was associated with increased bleeding (10.5% vs 61.5%, P=.005). On multivariable analysis, only anticoagulation use (OR 4.5, 95% CI: 2.1–10.0), male sex (OR 1.8, 95% CI: 1.1–2.9), and operative oversewing (OR 3.5, 95% CI: 1.8–6.9) were associated with delayed bleeding. Conclusion Post-hemorrhoidectomy bleeding is more likely to occur with patients on anticoagulation. Later restart times within the first week after surgery was not associated with a decrease in bleeding.
