Radical perianal abscess surgery is the removal of a perianal abscess in one visit. Generally, an incision is made in the abscess area to drain the pus, and a probe is used to find the internal opening of the abscess in the anus, and after finding the internal opening, the tissue on the probe is cut. If it is a high complex fistula, a skin band is hung and the internal opening is treated cleanly, which is radical surgery of perianal abscess. After radical surgery, the abscess usually heals and does not recur. However, because there are 6-8 anal sinuses in the human body, this time the infected sinus will not recur after removal, but the other sinuses are normal and may become infected later, and after infection the other sinuses may form a new perianal abscess, which can also be called a recurrence and is actually caused by a new sinus infection.
