hemorrhoids or anal cancer,What is anal fistula? Why must anal fistula be treated surgically?

    The full name of anal fistula should be anorectal fistula. It is also called anorectal fistula in Chinese medicine. It is a tube formed after the soft tissue around the anus and rectum is infected and purulent, ulcerated or cut artificially. This kind of tube begins to be one. As the disease progresses, it can be There are multiple. The inner mouth of the duct is the entrance to the infection. More than 90% are located in the anal sinus about 4 cm from the anal mouth. The outer mouth of the duct is the ulcer or surgical incision, mostly outside the anus, but also in the anus. Inner or rectal wall.

    Anal fistula is a common anorectal disease. China accounts for about 10% of the anorectal morbidity. It is not uncommon for young adults between the ages of 20-40 and infants. Its impact on the human body is repeated perianal infections, swelling and pain, scarring of perianal tissues, a small number of long-term anal fistulas, more than 10 years, have a certain tendency of malignant transformation.

    Anal fistula, like paraanal abscess, is different from infections in other parts of the body. Because it occurs near the anus and rectum, there is a fixed source of infection in the anus or rectal cavity, that is, the internal mouth. At the same time, the lesion is located in the anal sphincter, and the relaxation and contraction of the sphincter will Affect the discharge of pus. Therefore, once anal fistula and paraanal abscess occur, no matter how serious they are, there is no possibility of self-healing. Drug treatment will only relieve symptoms. Clinically, only surgical treatment can achieve the purpose of healing. In the past, many people tried to use multiple methods other than surgery, but they all ended in failure. To say the least, no non-surgical method has been found to cure anal fistulas and perianal abscesses.

    The purpose of anal fistula surgery is to cut the fistula, remove the internal opening, completely eliminate the source of infection, allow the fistula to drain, and allow the new granulation tissue to grow upward from the bottom of the wound and gradually fill the wound.
