Left Amyand's hernia associated with omphalocele

Amyand's hernia is defined as the presence of the cecal appendix inside the hernia sac. It is usually located on the right side, but left-sided cases due to intestinal malrotation have also been reported.

3-month-old male infant diagnosed with omphalocele at the 12th week of gestation undergoing surgery 48 hours post-birth. Bilateral inguinal hernia was diagnosed during follow-up, so scheduled bilateral herniotomy was performed. During surgery, the cecal appendix was identified inside the left herniary sac, so prophylactic appendectomy was carried out.

The incidence of Amyand's hernia ranges from 0.4 to 1% - three times higher in pediatric patients. Left-sided hernias are often associated with intestinal rotation disorders. Treatment of right Amyand's hernia is described in Losanoff-Basson's classification. In left-sided hernias, prophylactic appendectomy is recommended to avoid diagnostic confusion in case of appendicitis.
