Summary
Identifying specific anatomical zones during open inguinal hernia repair can help surgeons locate the three main inguinal nerves, potentially reducing chronic postoperative pain. Further studies are needed to confirm clinical effectiveness.
Area of Science:
- Anatomy
- Surgical Procedures
- Pain Management
Background:
- Chronic pain after open inguinal hernia repair often stems from somatic and neuropathic sources.
- Identifying inguinal nerves during surgery may decrease postoperative chronic pain.
- This study aimed to define surgical anatomical zones for efficient inguinal nerve identification.
Purpose of the Study:
- To define clinically relevant surgical anatomical zones.
- To facilitate efficient identification of the three inguinal nerves during open herniorrhaphy.
Main Methods:
- Dissection of 18 human cadaver inguinal areas (embalmed and unembalmed).
- Development of identification zones for inguinal nerves, focusing on the genital branch of the genitofemoral nerve.
Main Results:
- Defined anatomical landmarks for the iliohypogastric nerve (3.8 cm from external ring).
- Described the course of the ilioinguinal nerve relative to the spermatic cord.
- Characterized the laterocaudal course of the genital branch of the genitofemoral nerve at the internal inguinal ring.
Conclusions:
- Newly defined zones enable intraoperative identification of all inguinal nerves.
- Further research is required to assess clinical feasibility and impact on chronic pain incidence.
