Abstract
An 84-year-old man visited our hospital with a chief complaint of a painful mass in the right inguinal region. Based on abdominal computed tomography (CT), a diagnosis of right femoral hernia in which the hernial contents were the intestinal tract was made, but there were no clear findings of intestinal obstruction. Confirmation of the hernial sac at emergency surgery showed that it was filled with dark red ascitic fluid having an unusual odor, with incarceration of the appendix. Appendectomy was performed, and the femoral ring was repaired using McVay's method. Incarceration of the appendix in the hernia sac, or so-called de Garengeot's hernia, has rarely been reported. The possibillity of incarceration of the appendix should be considered in cases of incarcerated hernia without symptoms of intestinal obstruction.
