Surgical Management of 33 Ilioinguinal and Iliohypogastric Neuralgias at Louisiana State University Health Sciences Center

OBJECTIVE:This is a retrospective review of 33 charts of patients with ilioinguinal and iliohypogastric neuralgias who underwent a neurectomy at Louisiana State University Health Sciences Center between 1967 and 2000. Operations associated with neuralgias and postoperative pain outcomes were analyzed. METHODS:There were 23 ilioinguinal and 10 combined ilioinguinal-iliohypogastric neuralgias, and the side of the lesion and sex of the patient were found to be evenly distributed in this group. Nerve blocks must have resulted in a complete or substantial decrease in pain before a neurectomy was recommended. Twenty-nine (88%) of 33 neuralgia patients had injuries from iatrogenic causes, and 4 (12%) injuries were caused by blunt trauma. In the 23 isolated ilioinguinal neuralgias, the operation associated with neuralgias in 13 (57%) of 23 patients was a herniorrhaphy. This was followed by 4 (17%) neuralgias after an appendectomy and 3 (13%) after a hysterectomy. Three (13%) patients had neuralgias resulting from blunt trauma. Nine (90%) of 10 ilioinguinal-iliohypogastric lesions were caused by iatrogenic causes, and 1 (10%) neuralgia resulted from blunt trauma. A neurectomy was performed in all patients. RESULTS:The neurectomy resulted in considerable pain relief in 21 (91%) of 23 patients with ilioinguinal lesions and 9 (90%) of 10 patients with ilioinguinal-iliohypogastric lesions. Postoperative side effects were persistent numbness below the resected nerve and loss of the cremasteric reflex. Minor postoperative complications consisted of two superficial skin infections. CONCLUSION:Ilioinguinal and ilioinguinal-iliohypogastric neuralgias are infrequent conditions; however, 33 patients from the Louisiana State University Health Sciences Center were accrued and analyzed in this study, and most had significant pain relief after neurectomy.
