Quantitative Sensory Testing and Analysis of Post Inguinal Hernia Surgery Pain

Completed

Conditions studied: Hernia

In brief

Increasing experience has identified post-herniorraphy chronic pain as an under-recognized and important complication. Nerve entrapment and injury are recognized as causes of such pain. Operative treatment for selected patients with this condition includes surgical exploration of the affected groin, identification and removal of involved nerves, and removal of meshoma. This procedure has been highly effective in treatment of chronic pain. This study will attempt to subjectively and objectively evaluate the patient's chronic groin pain using quantitative sensory testing (QST) and validated pain scales and questionnaires. Quantitative sensory testing is a method used to assess damage to the small and large nerve fibers. It is used to diagnose and assess the severity of nerve damage, and can also help to determine if a neuropathy is responding to treatment. QST uses a computer testing system to measure how nerves react to vibration and changes in temperature. The procedure is non-invasive and the patient will feel minimal to no discomfort during testing. The hypothesis is that any decrease in subjective pain scores would be accompanied by improved QST results.
