Amyand's hernia: a series of 30 cases in children.

Amyand's hernia is a very rare condition with a presence of a vermiform appendix in an inguinal hernia sac. It is estimated to be found in approximately 1% of adult inguinal hernia. In this study, we report a retrospective analysis of 30 patients aged between 19 days and 8 years with an Amyand's hernia operated in our institution from 1998 to 2009, and we reviewed the literature on the topic. Hernia repair without an appendectomy was performed in patients with normal appendix. Emergency appendectomy through herniotomy was performed in cases of inflamed and perforated appendices.
