Abstract
A 75-year-old woman developed left inguinal pain associated with a left inguinal swelling about 20 cm in size. A plain abdominal computed tomography scan showed an indirect left inguinal hernia with bowel loops within the sac. Emergency surgery was performed for the left incarcerated inguinal hernia. Serosanguineous ascites and ileocecum were found in the hernia sac. Cases of incarcerated iliocecum in an inguinal hernia are very rare in the Japanese literature, especially those occurring in females and on the left side.
