Surgeon experience increases nerve identification during Lichtenstein hernia repair: a nationwide register-based study - 11/08/25
, Camilla Christophersen , Jason Joe Baker , Jacob Rosenberg Abstract |
Background |
Surgeon volume affects outcomes in hernia surgery, but it is unknown whether it also affects nerve identification. Therefore, we aimed to investigate whether increasing surgeon volume improved the identification rates of the ilioinguinal and iliohypogastric nerves during open inguinal hernia repair.
Methods |
All adult patients registered in the Danish Hernia Database who had undergone a Lichtenstein inguinal hernia repair between 2017 and 2023 were included. Each procedure was grouped depending on the number of procedures the surgeon had performed the previous year.
Results |
We included 17,492 hernia repairs. The ilioinguinal nerve identification rate peaked at 82 % for surgeons performing 20–29 annual repairs. The iliohypogastric nerve identification rate steadily increased, reaching 81 % for surgeons with ≥30 annual repairs.
Conclusion |
An annual surgical volume of ≥30 repairs improved nerve identification rates, reflecting the importance of maintaining continuous experience to enhance familiarity with the surgical field in open inguinal hernia repair.

• | We used prospectively collected data on 17,492 open inguinal hernia repairs. |
• | Ilioinguinal nerve identification plateaued after 20–29 repairs/year. |
• | Iliohypogastric nerve identification increased through all experience categories. |
• | Performing ≥30 annual repairs may enhance familiarity with the surgical field. |
