What causes anal cysts?

Anal cyst is a disease caused by anal bacterial infection, injury, anal fissure, and drug stimulation. After suffering from anal cyst, patients usually have inflammation and other problems. Therefore, it is necessary to know that these are caused by these adverse factors. It can be treated through surgery. Patients should also pay attention to it in life and control the inflammation of the anus in time to avoid complications.

Cause: The cause is mostly caused by anal gland infection, and may also be secondary to perianal skin infection, injury, anal fissure, internal hemorrhoids, and drug injection.

Causes of perianal cysts

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.

The diagnosis is generally not serious. The important symptoms are persistent throbbing pain around the anus, difficulty in movement, restlessness, and no obvious systemic infectious symptoms. The lesions are obviously red and swollen, with nodules and tenderness. There may be a sense of fluctuation when abscesses are formed, and pus is drawn out during puncture.

Check by touch, probe inspection, dye injection, and hydrogen peroxide perfusion.

The interventional method includes low-level incision, high-level latex tube drainage, and hydrogen peroxide perfusion. The hydrogen peroxide perfusion method is suitable for various fistulas, especially high-level and complex ones.

Method: Under the trumpet-shaped anoscope, insert 3 to 4 dry cotton balls above the internal tooth line of the rectum to prevent hydrogen peroxide from flowing into the rectal cavity and burning the intestinal mucosa. Connect a syringe filled with hydrogen peroxide to a thin plastic tube and insert it into the outer opening of the anal basket. Press the outer opening moderately with gauze and slowly push the injection into the tube from the outer opening. White foam can be seen flowing out from the inner opening under the anoscope.

The fistula formed between the rectum and the perianal skin or mucosa is called anal fistula. The fistula formed due to infection around the anus is called acquired anal fistula. The difference between it and congenital anal fistula is that acquired anal fistula has a normal anus. The anal fistula usually refers to acquired anal fistula, and when it comes to congenital anal fistula, it is usually included.
