What causes perianal abscess?

Perianal abscess is a common perianal infectious suppurative disease. The causes of its formation are more complicated. It is not only related to infection factors and marital factors, but also some post-operative infections can induce the occurrence of the disease. Diet control is also considered a common cause of perianal abscess. If you want to stay away from this disease, avoid the existence of these factors in your life.

1. Infection factors

Contemporary medicine believes that infection is the main cause of perianal abscesses. Anorectal abscesses can be formed due to anal fissures, hemorrhoids, hidradenitis of the skin folliculitis around the anus, and perianal skin diseases. Diseases such as ulcerative colitis, aplastic anemia, and systemic malnutrition can weaken the body, reduce resistance, and induce perianal abscesses.

2. Iatrogenic factors

Abscesses around the anorectum are also more common. For example, submucosal abscesses are caused by improper operation or unclean drugs; injection of chemicals around the rectum irritates the local area, causing tissue necrosis and causing perirectal abscesses; sigmoidoscopy can induce peritoneal perforation infection, causing retrorectal space abscesses, etc.

3. Surgical factors

The incidence of perianal abscess may also be related to surgical factors, because in clinical practice, perianal abscess caused by anorectal surgery is also very common. Postoperative infection of the urethra, postoperative infection of the perineum, and postoperative infection of coccyx osteomyelitis can also cause abscesses.

4. Improper diet

Irregular or overly spicy diet can also cause endogenous dampness and heat in the patient's body, and dampness and heat toxins can flow into the anus, causing this disease.

V. Other factors

Infection after rectal foreign body injury, rectal diverticulitis infection, rupture of anorectal cancer or deep infection, physical weakness, low resistance, chronic wasting disease or malnutrition are the causes of anorectal abscess.
