The concept of hidden hernias was first introduced in the 1970s by two separately interested surgeons from the United States: William Webb from Alabama and Jack Herrington from Wisconsin. They each noticed that women were presenting with symptoms suggestive of inguinal hernia; however, the surgeons had a hard time diagnosing hernia on physical examination. Their patients reported intermittent pain along the inguinal canal that was related to physical activity. However, the physical examination was essentially normal and “without detectable impulse.”
