What causes perianal abscesses?

Perianal abscess is a common and serious anorectal disease, which generally refers to swelling and pain around the anus accompanied by purulent secretions. If it does not heal for a long time, it can easily cause diseases such as anal fistula, causing great pain to patients. Although perianal abscess is common, many patients still do not know the specific reasons for its formation.

1. Infectious factors : Modern medicine believes that infection is the main cause of this disease.

1. Anorectal abscesses may form due to infections such as anal fissures, hemorrhoids, anal sinusitis, hidradenitis of the skin folliculitis around the anus, and skin diseases around the anus.

2. There are also certain diseases such as ulcerative colitis, aplastic anemia, and general malnutrition, which make the body weak, reduce resistance, and induce perianal abscesses.

2. Iatrogenic factors: In clinical practice, anorectal abscesses caused by iatrogenic factors are also not uncommon.

1. The treatment of internal hemorrhoids with hemorrhoid-insertion Ding can cause submucosal abscess due to infection caused by improper operation or unclean medicine.

2. Injection of chemical drugs around the rectum can cause tissue necrosis and lead to perirectal abscess.

3. Postoperative factors: Clinically, we can also see infections caused by anorectal surgery, resulting in perirectal abscesses, as well as abscesses caused by postoperative urethral infection, postoperative perineal infection, postpartum perineal rupture suture infection, and postoperative infection of coccyx osteomyelitis.

4. Others: Gunshot or knife wounds, infection after foreign body injury in the rectum, lymphogranuloma, actinomycosis, rectal diverticulitis infection, anorectal malignancy and ulceration or deep infection, as well as physical weakness, low resistance, chronic wasting diseases, or malnutrition are all causes of anorectal abscess.
