Evaluation of Tension-Free Inguinal Hernia Repair in Elderly Using Ultrasound-Guided Local Anesthesia
Overview
This retrospective study compared ultrasound-guided local anesthesia with epidural anesthesia in elderly patients undergoing day surgery for inguinal hernia repair. Ultrasound-guided local anesthesia was associated with lower postoperative pain, faster mobilization, shorter exhaust time, and fewer complications such as acute urinary retention.
Background
Inguinal hernia is a common condition in elderly patients, who represent the majority of adult cases requiring surgery. Day surgery for inguinal hernia aims to safely discharge patients within 24 hours, necessitating careful perioperative management and anesthesia selection. Ultrasound-guided local anesthesia offers a targeted nerve block technique that may improve outcomes compared to traditional epidural anesthesia in this population.

Key Findings
Ultrasound-guided local anesthesia significantly reduced postoperative pain at 4 hours compared to epidural anesthesia (VAS 2.71 vs. 5.23).
Patients receiving local anesthesia mobilized earlier postoperatively (3.35 vs. 7.35 hours).
Postoperative gastrointestinal recovery, measured by exhaust time, was faster in the local anesthesia group (5.52 vs. 10.35 hours).
The incidence of acute urinary retention was lower with local anesthesia (1.3% vs. 4%).
Two weeks after surgery, patients in the local anesthesia group had a higher rate of unrestricted activity recovery.
All patients were safely discharged within 24 hours, supporting the feasibility of day surgery in elderly patients with appropriate anesthesia choice.
Clinical Implications
Ultrasound-guided local anesthesia for tension-free inguinal hernia repair in elderly patients enables effective pain control and faster postoperative recovery compared to epidural anesthesia. This technique may reduce complications such as urinary retention and facilitate earlier mobilization, making it a valuable option for day surgery protocols in this population.
Conclusion
Ultrasound-guided local anesthesia is a safe and effective alternative to epidural anesthesia for elderly patients undergoing day surgery for inguinal hernia repair, improving postoperative outcomes and supporting rapid recovery.
