A Randomized Controlled Study Evaluating Pre-operative Etanercept on the Severity of Postoperative Pain After Inguinal Hernia Surgery.

Detailed Summary

Inguinal hernia repair is one of the most frequently performed operations in young men. Persistent pain after inguinal surgery represents a significant cause of disability, occurring in between 15%-35% of cases. In a majority of these patients, their groin pain persisted after a previous hernia repair. The main type of chronic postsurgical pain is neuropathic, caused by injured nerves. One of the principal components in the pathophysiology of postsurgical pain is cytokines, specifically tumor necrosis factor (TNF). In animal studies, injecting TNF inhibitors before nerve injury can reduce pain behaviors and neuropathology. Finding a way to reduce the incidence of postsurgical pain after hernia repair could enhance function, and reduce the need for opioids and other analgesics. The investigators intend to conduct the first randomized, controlled study evaluating whether preemptive administration of a tumor necrosis inhibitor can reduce postoperative pain and opioid consumption after hernia repair. This is important because the degree and intensity of postsurgical pain is a major predictor for the development of chronic postsurgical pain.
