Under normal circumstances, perianal abscess only needs one operation to achieve the goal of radical cure, and no longer recurs, but some cases also require a second operation. For example, some doctors are accustomed to performing secondary surgery for perianal abscess, or because of the severe condition of the perianal abscess and the weak constitution of the patient, they cannot bear the incision and drainage caused by radical surgery. They need to wait until the inflammation has subsided and form an anal fistula. Second surgery.

　　Perianal abscess is a common anorectal Diseases, for anorectal diseases, are generally treated with drugs or surgery. Especially for surgery, it usually takes only one time to achieve the goal of radical cure, but some patients need to undergo a second operation after the disease, so that the condition can be fully recovered. This makes many patients feel worried after getting sick. Why do some perianal abscess require a second operation?
　　First, why some perianal abscesses require a second operation
　　Under normal circumstances, only one operation can solve the perianal abscess. Through the operation, the primary infection of the perianal abscess can be removed at one time, and the goal of radical cure can be achieved without recurrence. The second operation is mainly incision and drainage, only to relieve local discomfort symptoms and reduce inflammation, and wait for anal fistula to form a clear inner mouth or fistula, then do anal fistula radical surgery. The reasons for the second operation are mainly divided into two categories. On the one hand, clinicians are accustomed to performing secondary surgery for perianal abscess; on the other hand, the perianal abscess is more serious, or the patient is weak and cannot withstand the incision caused by radical surgery. Drainage surgery needs to reduce the further damage caused by inflammation to the body, and wait for the second operation after the inflammation subsides to form an anal fistula.
　　Second, what are the causes of perianal abscess?
　　1. Infectious factors
　　If you have other anorectal diseases, such as anus Infections such as fissures, hemorrhoids, anal sinusitis, or hair follicle sweat gland inflammation around the anus and skin diseases around the anus can form abscesses around the anus and rectum.
　　2. The body is too weak
　　Certain diseases such as ulcerative colitis, aplastic anemia, systemic malnutrition and other chronic diseases will make the patient weak and the resistance decline significantly , It is also easy to induce the occurrence of abscess around the anus.
　　3. Surgical factors
　　 Clinically, the occurrence of abscesses around the rectum due to infection of anorectal surgery can also be seen. In addition, infections after urethral surgery and pudendal surgery, postpartum perineal rupture and suture infection, and gastric sacral osteomyelitis postoperative infection can also induce abscesses.
