Amyand’s hernia in children: A 20-year experience at a tertiary referral hospital

Abstract

Aim: Amyand’s hernia is detected in 0.42%–1% of children with inguinal hernia (IH) and is quite difficult to diagnose prior to surgery.
There is no consensus on its treatment.
Materials and Methods: The records of patients who underwent IH repair and were diagnosed with Amyand’s hernia between 2001
and 2019 were retrospectively analysed in terms of age, gender, complaints at presentation, side of IH, treatment methods (with
appendectomy or reduction of appendix), complications, duration of hospital stay and follow-up.
Results: In total, 3,577 patients (male/female: 3,045/532) who underwent surgery for IH and 1,898 patients who underwent
appendectomy were analysed. Cases with Amyand’s hernia (n=47, male/female: 41/6) accounted for 1.31%, 1.4% and 0.31% of all IH,
incarcerated/strangulated hernia and appendectomy cases, respectively. The median age was 3 months. In one case, the appendix
was located within the left hernial sac. One patient presented with a complaint of recurrent abscess in the right inguinal region. In all
cases, the diagnosis was made intra-operatively based on identification. In 23.4% of the cases with Amyand’s hernia, appendectomy
was performed. In 46 of the 47 cases diagnosed with Amyand’s hernia, inguinal transverse incision and high ligation procedures
were performed. Acute appendicitis did not develop during follow-up in cases without appendectomy.
Conclusion: Because the appendix plays an active role in the immune system, especially during childhood, and is used in some
pathologic cases as luminal supportive tissue, we believe that appendectomy should not be performed if there are no signs of
inflammation and the appendix can be reducted into the abdomen.
