Indications for the Treatment of Hemorrhoids

Only 30 years ago, hemorrhoids were assumed to be an abnormal structure caused by varicose vein. Also, after the sliding anal lining theory introduced by Thompson from United Kingdom in 1975, many other studies were presented to support this theory that is now accepted worldwide. However, the vascular hyperplasia theory deserves reconsideration. According to the sliding anal lining theory, the hemorrhoids are regarded as normal structure that closes the anal canal. Therefore, the treatment of hemorrhoids should not simply remove or destroy the hemorrhoid structure but rather focus on relieving the symptoms that patients claim.
