If you feel redness, swelling, moisture and stinging around the anus, be careful of these diseases!

When some patients find redness, swelling, moisture and stinging around the anus, they always think it is caused by getting angry and that taking some anti-inflammatory drugs can cure it. In fact, it is not that simple. You must be careful to prevent infections such as pus, fistulas, fistulas, cancer, and other adverse diseases.

1. Causes of perianal abscess

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

2. Iatrogenic factors: Anorectal abscess caused by iatrogenic factors is not uncommon in clinical practice.

3. Postoperative factors: Clinically, we can also see perrectal 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. Patients should choose a regular anorectal specialty hospital for treatment, Shanghai Zhongyou Anorectal Hospital is a good one.

4. Others: Infection after foreign body injury in the rectum, actinomycosis, rectal diverticulitis infection, rupture of anorectal cancer or deep infection, as well as physical weakness, low resistance, or chronic wasting diseases, or malnutrition are all causes of anorectal abscess.

2. Beware of perianal abscess developing into anal fistula

1. Infection and pus discharge: Once anal fistula is formed, there is little chance of self-healing and it will bring a series of hazards. First, after the anal fistula becomes infected and inflamed, the anus will be extremely painful. After it ruptures, pus will stain the underwear, irritate the local skin, and cause severe anal itching. Over time, it can cause the body to become weak and thin, lack of energy, decreased disease resistance, and more frequent attacks, forming a cause and effect relationship.

2. Increase in fistula openings and fistula tracts: Repeated attacks of anal fistulas may cause pus to penetrate the tract wall and spread along the sphincter gap to form multiple and complex anal fistulas, which not only make treatment difficult but also affect the physiological function of the anus.

3. Risk of cancer: The multiple occurrence of anal fistulas can form rectovaginal fistulas, rectourethral fistulas and rectovesical fistulas, endangering the surrounding organs. In addition, old anal fistulas that have not been treated for many years or have been treated incorrectly may become cancerous.

4. Anal incontinence: If the abscess is allowed to develop, it may cause serious damage to the sphincter and may even cause complications such as anal incontinence.
