Comparative Study of Preservation versus Elective Division of Ilioinguinal Nerve in Open Mesh Repair of Inguinal Hernia
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 1
Abstract
Introduction: Chronic postherniorrhaphy groin pain is defined as pain lasting for more than 3 months after surgery. It is one of the most important complications occurring after inguinal hernia repair and it occurs with greater frequency than previously thought. Aim: The purpose of this study is to evaluate the effect of routine ilioinguinal nerve excision compared to nerve preservation on chronic groin pain and other sensory symptoms when performing Lichtenstein tension free inguinal hernia repair. Materials and Methods: A total of 60 patients underwent open mesh repair of inguinal hernia were included in the study. The ilioinguinal nerve was identified and preserved in 30 patients (Group A), and elective division of the ilioinguinal nerve was done in 30 patients (Group B). The patients were evaluated for pain and other sensory symptoms at post-operative day 1 (POD-1), at 1 month, at 3 months, and at 6 months after surgery by using 4-point verbal scale. Results: About 50 out of 60 patients completed the study protocol fully. The incidence of post-operative groin pain in this study compared ilioinguinal nerve preservation versus routine excision of ilioinguinal nerve showing was 24 versus 19 at POD-1; 13 versus 10 at 1 month, 26.9% versus 12.5% at 3 months, and 19.2% versus 8.2% at 6 months. The incidence of hypesthesia was 57.6% versus 62.5% at POD-1, 26.9% versus 37.5% at 1 month, and 11.5% versus 16.6% at 6 months. The incidence of post-operative numbness compared ilioinguinal nerve preservation versus nerve excision, results showed 23% versus 25% at 1 month and 11.5% versus 12.5%. Conclusion: The prophylactic excision of the ilioinguinal nerve during Lichtenstein mesh hernia repair decreases the incidence of chronic groin pain after surgery.
