(2) Which hemorrhoid patients need surgical treatment Surgical treatment is mainly used for patients with degree III and IV hemorrhoids. (1) Frequent bleeding in the stool, frequent episodes, large amount of blood in the stool, and the effect of drug treatment is not obvious. (2) The hemorrhoid nucleus is large and prolapses out of the anus after stool, and cannot be retracted into the anus by itself, and requires hand support, lying down and resting, and hot compresses to retract into the anus. (3) The nucleus of hemorrhoid prolapses outside the anus, internal hemorrhoid is embedded, external hemorrhoid is edematous, and the anus is painful.

However, the current hemorrhoid surgery technology is more mature, the risk is not big, especially the application of minimally invasive technology, greatly reducing the pain of patients. The reason is that even if you have surgery, you may still have a recurrence, and if you don’t take proper care of your hemorrhoids after surgery, you may have various complications, so surgery is not a “one and done” solution. If you have to have surgery, go to a regular hospital, do not believe in the small advertisements of some unscrupulous businessmen, otherwise you may regret the small surgery for the rest of your life.
