| indirect inguinal hernia | <surgery> The abnormal passage of an internal abdominal organ or structure through the inguinal canal. In males, this will result in a unilateral bulge in the scrotum, in females there will be unilateral swelling in the region of the labia majora. Inguinal hernias are classified as direct or indirect on the basis of the anatomic path the hernia undertakes through the inguinal canal. Many hernias will reduce (go away) on their own but return at times of straining or lifting. A hernia that does not go away and causes pain is a surgical emergency. (27 Sep 1997) |
