The Impact of Perioperative Gabapentin on Chronic Groin Pain After Inguinal Hernia Repair

Summary

A common source of morbidity after IHR is chronic groin pain(CGP), usually defined as pain lasting longer than 3 months. Gabapentin is an anticonvulsant that is also of benefit in the treatment of neuropathic pain. We propose a randomized, double-blind, placebo controlled study of the effect of gabapentin on CGP after IHR. Their pain will be assessed with a visual analogue scale. For those reporting pain, the need for pain medication, or other treatment, and the effect of pain on their quality of life will be recorded.
