Abstract
IntroductionPreoperative inguinal pain (painful inguinal hernia) is a well-known factor associated with chronic postoperative inguinal pain (CPIP). However, it remains unclear what preventive measures should be taken in such patients.Case presentationWe report two patients with painful inguinal hernia who underwent pragmatic ilioinguinal nerve neurectomy during open anterior repair. The nerve was compressed by bulky spermatic cord lipoma in case 1 and by the hernia sac presenting over a few decades in case 2. Hematoxylin and eosin staining of the resected nerves revealed mucoid degeneration. Toluidine blue staining of resin-embedded nerve sections demonstrated that fully-myelinated axons had significantly decreased in case 1 and almost disappeared in case 2, indicating the development of massive demyelination of the ilioinguinal nerve in both cases.DiscussionIn cases where the injured nerve is left in situ, CPIP may occur since demyelinating neuropathy sometimes becomes irreversible.ConclusionPlanned nerve resection via open anterior inguinal hernia repair may be an option to prevent CPIP in patients with painful inguinal hernia.

Summary
Preoperative inguinal pain (painful inguinal hernia) is a well-known factor associated with chronic postoperative inguinal pain (CPIP) It remains unclear what preventive measures should be taken in such patients. Case presentation: We report two patients with painful inguinal hernia who underwent pragmatic ilioinguinal nerve neurectomy during open anterior repair. There are various risk factors involved in the development of CPIP, including the presence of inguinal pain before surgery [2] It remains unclear what preventive measures should be taken in such patients [3]. In this case report, we describe the pathological specimens of pragmatically-resected ilioin guinal nerves during open anterior inguinal hernia repair in two patients with painful inguinal hernia. This case report is reported in line with the SCARE criteria [4]
