BACKGROUND: Previous reports document the safety of open inguinal herniorrhaphy in patients on chronic warfarin therapy; however, the practice remains controversial. This study is a 10-year update of our experience. METHODS: A retrospective review of 1,839 consecutive patients undergoing open inguinal hernia repair was conducted from 2000 to 2010. All patients on chronic warfarin therapy were included. Three groups: continuation (CW), discontinuation (DW) and case-matched control (C) not on warfarin therapy were compared for operative details and postoperative complications. RESULTS: One hundred and fifty-eight patients were on chronic warfarin therapy. Of these, 40 patients (25%) continued on warfarin during the perioperative period (CW). Average preoperative international normalized ratio (INR) was 2.15 ± 0.76 for CW and 1.38 ± 0.42 for DW, p < 0.001. Mean operative times were equivalent between all three groups (88 min CW vs. 85 min DW vs. 79 min C, p = 0.518). Although CW patients experienced higher incidences of both hematoma and urinary retention overall, no statistically significant differences in complication rates were seen between the three groups (hematoma = 10 vs. 8% DW vs. 5% C, p = 0.703; urinary retention = 15 vs. 10% DW vs. 8% C, p = 0.541). Comparing patients by INR, there were no statistically different postoperative complication rates, particularly for hematoma (8% INR <2 vs. 9.5% INR = 2-3 vs. 20% INR >3, p = 0.65). CONCLUSION: Maintenance of warfarin therapy during the perioperative period for open inguinal herniorrhaphy results in equivalent operative times and postoperative complications as discontinuation.
