Purpose
An aging population has led to an increased number of patients with cardiovascular comorbidities requiring antithrombotic therapy. Perioperatively, surgeons should consider the increased risk of bleeding and thrombotic events in patients continuing or discontinuing these medications. We aimed to analyze the safety of continued antithrombotic therapy during open inguinal hernia repair.
Methods
In this single-center, retrospective study, 4870 adult patients who underwent open inguinal hernia repair surgery by the same surgeon from 2008 January to 2019 March were included. Patients who underwent surgery while continuing antithrombotic therapy were included in the antithrombin group (n = 523) while those who were not under any antithrombotic therapy during the surgery were included in the control group (n = 4333). Using propensity score-matching, we then selected patients from each group with similar backgrounds. Surgery time, anesthesia time, postoperative bleeding, reoperation, and thrombotic event data were compared between the groups. Subgroup analysis based on the type of medications used was performed within the antithrombin group.
Results
Ten patients in the antithrombin group and seven patients in the control group experienced postoperative bleeding (p < 0.001). The rate of postoperative bleeding was the highest in patients taking multiple medications. However, most were managed conservatively. Three patients from the antithrombin group experienced thrombotic events postoperatively (p = 0.001).
Conclusions
Patients receiving continued antithrombotic therapy had an increased risk of minor postoperative bleeding; however, they are a high-risk group for thrombotic events.
