Amyand's hernia in an elective inguinal hernia repair: A case report

Abstract

Introduction and importance: Amyand's hernia is a rare condition in which the appendix is situated inside an inguinal hernia sac. It occurs in less than 1 % of all inguinal hernias, and preoperative diagnosis is often challenging, even with the aid of ultrasonography or computed tomography. The course of treatment depends on the degree of inflammation of the appendix. In this report, we present a case of Amyand's hernia that was discovered during elective inguinal hernia repair.

Case presentation: We are presenting a case of a 65-year-old man who complained of right inguinal swelling and pain for one week. Upon clinical examination, a nontender and reducible mass was discovered in his right inguinal region. Further ultrasound examination suggested the presence of a right inguinal hernia, without any additional notable findings. During the surgery, the appendix was found to be present inside the indirect inguinal hernia sac, and due to its normal condition, the hernia was reduced, and a prosthetic mesh was placed.

Clinical discussion: Amyand's hernia is a rare form of inguinal hernia, predominantly found in men, with the appendix being trapped within the inguinal canal. The clinical presentation and treatment depend on the appendix's inflammation, and while ultrasonography is commonly used for diagnosis, preoperative detection of Amyand's hernia is often challenging.

Conclusion: Amyand's hernia is a rare but potentially life-threatening condition. A high index of suspicion is required to make the diagnosis. Surgical intervention is the treatment of choice, and In the absence of complications, the prognosis is favorable.
