Appendix in recurrent hernia sac (Amyand’s hernia)

Amyand’s hernia refers to the condition in which an inflamed, perforated, or normal appendix is present in the hernia sac. It accounts for 1% of all inguinal hernias and its preoperative diagnosis in patients is difficult. A 67-year-old male patient who underwent right-sided inguinal hernia repair with a mesh approximately 2 years before at another healthcare center was referred to our clinic with complaints of pain in his right inguinal area and swelling, which became evident while coughing or straining, for approximately 2 months. A surgical procedure to repair his recurrent inguinal hernia was planned, and appendiceal tissue was observed in the hernia sac during the procedure. Appendectomy was not performed because the appendix was observed to be normal. Tension-free mesh hernioplasty was performed. The patient was discharged on postoperative day 1, without any complications. Amyand’s hernia is generally intraoperatively diagnosed and is a rare form of hernia with no specific symptoms. In this case report, we showed that despite the patient undergoing a surgical procedure, the appendix was present in the hernia sac because of recurrence, and we aimed at reviewing Amyand’s hernia with the literature.
