The risk of recurrence of perianal abscesses, even after radical surgery, is determined by the pathogenetic characteristics of the disease. Most of the perianal abscesses develop because of glandular infection, and the presence of primary endografts above the anal dentition line leads to suppuration and infection of the perianal fatty tissue, and the local pus accumulates more and more, and the pressure is relatively high, which produces severe pain. Radical perianal abscess surgery is to further expand the pus cavity on the basis of incision and drainage, try to find the primary internal opening, and remove the internal opening, which is more thorough for the treatment of the disease. But even so, because the septic orifice of perianal abscess is not very stable, the doctor only looks for the orifice according to experience, but not necessarily the exact orifice, so there is still a risk of recurrence, and the disease of perianal abscess may also appear in other places around the anus.
