Comparative analysis of different surgical approaches for recurrent inguinal hernia: a single-center observational study.

Purpose: Managing recurrent inguinal hernias is complex, and choosing the right surgical approach (laparoscopic open) is vital for patient outcomes. This study compared the outcomes of using the same different surgical approaches for initial and subsequent hernia repairs.

Methods: We retrospectively analyzed patients who underwent recurrent inguinal hernia repair at Seoul National University Bundang Hospital between January 2014 and May 2023. Patients were divided into the "concordant" and "discordant" groups, comprising patients who underwent same and different approaches in both surgeries, respectively. Preoperative baseline characteristics, index surgery data, postoperative outcomes, and recurrence rates were analyzed and compared.

Results: In total, 131 patients were enrolled; the concordant and discordant groups comprised 31 (open, n = 19; laparoscopic, n = 12) and 100 patients (open to laparoscopic, n = 68; laparoscopic to open, n = 32), respectively. No significant differences were observed in the mean operation time (50.5 ± 21.7 minutes 50.2 ± 20.0 minutes, P = 0.979), complication rates (6.5% 14.0%, P = 0.356), or 36-month cumulative recurrence rates (9.8% 9.8%; P = 0.865). The mean postoperative hospital stay was significantly shorter in the discordant than in the concordant group (1.8 ± 0.7 1.4 ± 0.6, P = 0.003).

Conclusion: Most recurrent inguinal hernia repairs were performed using the discordant surgical approach. Overall, concordance in the surgical approach did not significantly affect postoperative outcomes. Therefore, the selection of the surgical approach based on the patient's condition and surgeon's preference may be advisable.
