Background: Chronic postherniorrhaphy inguinal pain is a complex, major health problem. In the absence of recurrence or meshoma, laparoscopic retroperitoneal triple neurectomy has emerged as an effective surgical treatment of postherniorrhaphy inguinal pain. Methods: This prospective pilot study evaluated the neurophysiological and clinical effects of laparoscopic retroperitoneal triple neurectomy. Ten consecutive adult with chronic postherniorrhaphy inguinal pain and unilateral predominantly neuropathic inguinodynia underwent three comprehensive quantitative sensory testing assessments (preoperative, immediate postoperative, and late postoperative). Pain severity, health-related function, and sleep quality were assessed over the course of a 6-month follow-up period.
