A Case of Irreducible Amyand’s Hernia

Abstract

Amyand’s hernia (AH), in which a vermiform appendix protrudes into the inguinal hernia sac, is rare. It is difficult to diagnose preoperatively, and intraoperative diagnosis is not unusual. Herein, we report a case of an AH patient who underwent an emergency operation for an incarcerated right inguinal hernia followed by an intraoperative diagnosis of AH. An 11-month-old boy was referred to our hospital owing to a bulge in his right groin and a bad temper for 9 h. Following unsuccessful manual reduction, an emergency operation was performed at 10 h from the onset. Laparoscopy revealed the protrusion of the ileocecal region into the right processus vaginalis, and manual reduction was successfully achieved. There was no significant inflammation in the vermiform appendix, and laparoscopic herniorrhaphy was performed. His postoperative course was uneventful with no recurrence during follow-up for two years. Laparoscopic surgery may be useful for AH.
