Retrospective comparative cohort analysis of Darn and Lichtenstein repair methods for bilateral inguinal hernias in adult males in a low-resource setting: a single-centre study in Sudan

While both methods yielded similar recurrence rates, Darn repair showed advantages in resource-limited settings, with fewer complications, shorter hospital stays, and lower costs, making it a practical option when mesh is not readily available. Limitations include retrospective design, convenience sampling, and possible recall bias from phone follow-ups. The three-month follow-up may not capture long-term outcomes like chronic pain or late recurrences. Future studies should extend follow-ups and conduct prospective trials to optimize Darn repair across diverse settings.
