Perianal abscess nodules are primarily caused by inflammatory infections that lead to local fibrosis, which then forms the nodules. For these nodules, it is recommended to employ a one-time radical cure surgery for perianal abscesses, mainly to remove the internal opening and the inflamed infected tissues. Since a perianal abscess can form a fistula after bursting on its own, failing to completely remove the infected tissue may lead to the development of anal fistulas later. Therefore, clinically, for perianal abscess nodules, it is advised to treat them with a one-time radical cure surgery for perianal abscesses. Post-surgery, medications such as anal washes and red oil ointment gauze strips are chosen for dressing changes. As for early-stage perianal abscess nodules, these are mainly inflammatory infections causing red and swollen lumps, which gradually turn into purulent and liquefied masses. Once suppuration occurs, they can be opened and drained, thereby causing the nodules to disappear. The nodules formed after incision and drainage are mainly considered to be from inflammatory spread to fibrotic tissue, and thus, surgical removal is required in these cases.
