Safety of Inguinal Hernia Repair in the Elderly with Perioperative Continuation of Antithrombotic Therapy

Introduction: This study aimed to evaluate the safety of an inguinal hernia repair (IHR) under local anesthesia (LA) in the elderly with a perioperative continuation of antithrombotic therapy (AT). Methods: A total of 120 patients undergoing elective primary IHR between August 2018 and August 2019 at the West China Hospital of China were prospectively studied, among which 60 patients also had coexisting cardiovascular diseases and had a continuation of AT perioperatively (antithrombotic group); the other 60 patients were not on any prior AT (control group). The primary endpoints were intra- and postoperative hemorrhagic complications, the required interventions for complications based on the Clavien-Dindo classification, and postoperative thromboembolic complications. The secondary endpoints were nonhemorrhagic complications, intraoperative duration, and postoperative length of stay (LOS). Results: None of the patients in both groups had significant intraoperative bleeding >10 mL, and there were no significant differences between the 2 groups in terms of the postoperative hemorrhagic complications: bruising (2 vs. 0%, p = 1.000), serosanguinous soakage (7 vs. 3%, p = 0.679), and no hematoma was observed. Interventions required for encountered complications based on the Clavien-Dindo classification grade I (7 vs. 5%, p = 1.000) were assessed. There were no episodes of postoperative thromboembolic complications within 60 days in both groups. There were also no significant differences between the 2 groups in terms of nonhemorrhagic complications, intraoperative duration, and postoperative LOS (p > 0.05 in all). Conclusions: The perioperative continuation of AT did not increase the risk of intra- and postoperative hemorrhagic complications following IHR in the elderly. Thus, IHR under LA seems to be safe and feasible in this setting.
