How are perianal cysts formed? Infection is the most common

Perianal cysts can cause pain, and the pain is particularly obvious, affecting walking. Common causes of perianal cysts are infection, hemorrhoids, anal fissures, anal sinusitis, and diseases such as ulcerative colitis.

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, iatrogenic anorectal abscesses are 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.

Postoperative factors

Clinically, we can also see perirectal abscesses caused by infection due to anorectal surgery, as well as abscesses caused by postoperative urethral infection, postoperative perineal infection, postpartum perineal rupture suture infection, and postoperative infection of coccyx osteomyelitis.

IV. Others

Causes of anorectal abscesses include gunshot or knife wounds, infection after foreign body injury in the rectum, lymphogranuloma, actinomycosis, rectal diverticulitis infection, rupture of anorectal cancer or deep infection, as well as physical weakness, low resistance, chronic wasting diseases, or malnutrition.
