When itchy trauma occurs after perianal abscess surgery, there should probably be two types of cases. One type is normal, which means that granulation tissue has appeared on the trauma. In the process of normal growth of granulation tissue, itchy symptoms will occur. There is no need for special treatment at this time, just let nature take its course. The other kind of post-operative itching of perianal abscess is abnormal. It may be that the intestinal fluid of the anus and the secretions of the perianal trauma are mixed together, stimulating the trauma and causing the patient to have anal itching. At this time, we must clean up the residual feces and perianal secretions in time to reduce the symptoms of itching and at the same time, we can also effectively avoid secondary perianal infection. You can also use potassium permanganate and other drugs and insist on daily sitz baths for the anal area, which can also relieve the itchy symptoms and promote wound healing.
