De Garengeot hernia

De Garengeot hernias are femoral hernias that contain the appendix.

It is not to be confused with Amyand hernia, which is an appendix-containing inguinal hernia.


It is a rare phenomenon, with only 1% of all femoral hernias containing the appendix (and usually found incidentally at surgery), and only 0.08-0.13% containing an incarcerated acute appendicitis (sometimes detected on pre-operative CT) 1.

History and etymology

It is named after Rene Jacques Croissant de Garengeot (1688-1759), Parisian surgeon, first described this pathology in 1731.
