Perianal abscess is an acute purulent infection that occurs around the anus and rectum. The source of infection is the anal sinus tissue at the junction of the anal canal and rectum in the anus. The infection bacteria are mainly Escherichia coli in the stool. The age of onset is mainly young adults between the ages of 20 and 40, and most of them are men. There is basically no possibility of self-healing after the occurrence of perianal abscess. This is because the primary site of perianal abscess is in the rectum, which pollutes the environment. Pathogenic bacteria and feces enter the infected abscess cavity from the infected anal sinus. This is like a sewage pond. The water inlet is open for a long time, and there is continuous sewage inflow. If the water inlet is not closed, the sewage in the pond cannot disappear.
Once the perianal abscess is diagnosed, it should be operated as soon as possible to prevent the spread of infection and increase the difficulty of the operation. At the same time, after the infection range is expanded, the surgical damage will inevitably increase; and if the perianal abscess is not treated in time, it can lead to bacterial blood. Symptoms and sepsis are life-threatening. Some perianal abscesses are treated with high-dose antibacterial drugs. Although the condition can be temporarily controlled, because the source of the infection is still there, it is inevitable to relapse after stopping the drug.
