Perianal abscess refers to the occurrence of acute purulent infection in the soft tissue around the anal canal and rectum or the surrounding space, and the formation of an abscess. Perianal abscess definitely requires surgical treatment. There are two types of surgery: 1. The method is traditional, which usually involves incision and drainage of pus first, and then a second operation is performed after an anal fistula is formed, which is called radical anal fistula resection. However, many anorectal specialist hospitals can currently use one-time radical resection, that is, one operation can completely treat the perianal abscess without having to incise and drain it to form an anal fistula and require a second operation. In this way, two surgeries are combined into one, which saves the patient from the pain of a second surgery, shortens the course of treatment, and reduces the patient's pain. You can consult the hospital for details.
