Preservation Versus Division of Ilioinguinal Nerve on Open Mesh Repair of Inguinal Hernia: A Meta-analysis of Randomized Controlled Trials
World Journal of Surgery, 06/04/2012
Hsu W et al. – Preservation of the ilioinguinal nerve during open mesh repair of inguinal hernia is associated with a decreased incidence of sensory loss at 6 and 12 months postoperatively compared with that of the division technique. No significant differences were found between the groups for chronic groin pain or numbness.Methods
- Authors conducted a systematic review and meta–analysis of randomized controlled trials that compared the outcomes of preservation versus division of the ilioinguinal nerve during open mesh repair of inguinal hernia.
- The primary outcome was the incidence of groin pain; secondary outcomes were numbness and sensory loss.
- Authors reviewed six trials with 1,286 patients.
- They found no difference between the groups for the incidence of groin pain or numbness at 1, 6, and 12 months after open mesh inguinal repair.
- The incidence of sensory loss or change was significantly higher in the division group than in the preservation group at 6 months [risk ratio (RR) 1.25; 95 % confidence interval (CI) 1.02–1.53] and at 12 months (RR 1.55; 95 % CI 1.01–2.37) postoperatively.
- No significant differences between the groups were noted at any other points in time.
