Neuralgia after inguinal hernia repair

Severe chronic pain after groin hernia repair is uncommon but potentially debilitating. Fifteen patients with this condition were retrospectively reviewed. All patients had severe pain, which prevented their working or normal activity and was refractory to nonoperative treatment. Essentials of therapy included 1) a preoperative attempt to identify the involved nerve and 2) high ligation and division of the involved nerve identified at exploration. Twelve patients obtained excellent results and were able to return to normal activity with no requirement for analgesia. Understanding of the typical nerve anatomy, as well as the individual variation in nerve anatomy, can help prevent this complication and is essential for correction if the complication does develop.
