ABSTRACT

Objective: To assess the persistent post-operative pain (inguinodynia) and hypostesia in patients after tension-free inguinorrhaphy (mesh) as compared to resection conserving the ilioinguinal nerve.
Setting: General Hospital of Mexico. O.D.
Design: Transversal, retrospective, observational, comparative study.
Statistics: Percentages as summary measure for qualitative variables and χ2 test.
Material and methods: Postoperated patients after unilateral primary inguinorrhaphy (December 2003 to 2004) with prosthetic material and informed on the management of the ilioinguinal nerve (Group A with resected nerve and Group B with conserved nerve). Direct variables: postoperative inguinodynia and hypostesia, assessed at one, six, and twelve months after surgery. Severity of pain was assessed with the analog visual scale (AVS), and hypostesia was assessed by the patient’s direct answer.
Results: Group A, 60 cases; Group B, 140. Frequency did not reveal a statistical difference between groups: 3 (5%) vs 5 (3.5%) (p = 0.22), at 6 months of 2 (3.3%) vs 6 (4.3%) (p = 0.09), and at 12 month of 2 (3.3%) vs 5 (3.5%) (p = 0.07). Hypostesia did show a significant difference between groups: group A of 13 (21.6%) vs 1 (0.7%) (p ≤ 0.01), at 6 months of 12 (20%) vs 4 (2.8%) (p ≤ 0.01), and at 12 months of 8 (13%) vs 4 (2.8%) (p ≤ 0.01). AVS: Group A, at one month › 5 in 2 patients, at 6 months › 5 in 1 patient, and at 12 months › 5 in 1 patient. In group B, AVS at one month was › 5 in 3 patients, at 6 months was › 5 in 4 patients, and at 12 months was › 5 in 3 patients.
Conclusion: Resection of the ilioinguinal nerve does not modify either inguinodynia or hypostesia after inguinorrhaphy.
