Pulsed radiofrequency for the treatment of ilioinguinal neuralgia after inguinal herniorrhaphy.
Ilioinguinal neuralgia secondary to inguinal hernia repair is frequently a chronic, debilitating pain. It is most often due to destruction or entrapment of nerve tissue from staples, sutures, or direct surgical trauma. Treatment modalities, including oral analgesics, nerve blocks, mesh excision, and surgical neurectomy, have varied success rates. Pulsed radiofrequency (PRF) has recently been described as a successful method of treating chronic groin pain. Unlike conventional radiofrequency, PRF is non-neurodestructive and therefore less painful and without the potential complications of neuritis-like reactions and neuroma formation. Although the mechanism is unknown, it appears that the interaction of an electromagnetic field and c-fos proteins may alter normal transmission of painful impulses. Our study examines five patients treated with PRF for ilioinguinal neuralgia secondary to inguinal herniorrhaphy. ⋯ Ilioinguinal neuralgia is challenging to treat. We have demonstrated the successful use of PRF for four out of five patients seen in our office.
