Amyand's Hernia: Appendix in Hernia or Hernial Appendicitis?

The presence of an appendix in the inguinal hernia sac is defined as Amyand's hernia (AH). This study intends to present the authors' experience in dealing with this entity and also to present a discussion on possible need of updating its definition, classification, and management.

A retrospective analysis of records of all pediatric patients undergoing surgery for congenital inguinal hernia in a single unit from January 2017 to March 2021 was done. Patient's demographics, clinical presentation, preoperative investigations, peroperative findings, and postoperative outcomes were recorded and analyzed.

AH was found in eight patients. All were boys. The median age of presentation was 20.5 months (range 2 months to 36 months). The mean duration of symptoms was 2 days (range 2 to 4 days). All patients presented with incarcerated inguinoscrotal swelling (right sided = 5, left sided = 3); associated with pain. An abdominal radiograph and ultrasonography were done for all. All patients underwent emergency surgery. Exploration was done for all through an inguinal incision. The appendix was found inflamed for two patients, and appendectomy was done for the same. None of the patients underwent incidental appendectomy. Wound infection, secondary appendicitis, and recurrence were not seen for any of the patients. The authors have also proposed a revised definition and classification of AH.

AH is an interesting entity and many questions like the need for incidental appendectomy remain unanswered. An updating of the definition and classification system can probably offer some solution in this regard. However, more research is warranted in this regard.
