Perirectal abscess

Perirectal Abscess

Anorectal abscess

An anorectal abscess is a pocket of pus in the tissue near the end of the rectum (anus). Most abscesses are caused by a blocked anal gland that develops an infection.

Other possible causes of an anorectal abscess include:

  • Infection in an anal fissure.
  • Complications of diseases that affect the colon, such as Crohn's disease, inflammatory bowel disease, or diverticulitis.
  • Sexually transmitted infections.

Symptoms of an anorectal abscess include:

  • A painful swelling (mass) around the anus.
  • Drainage of pus from the anus.
  • Fever.
  • Pain in or around the anus.
  • Pain when passing stool.

A person should see a doctor if an anorectal abscess is suspected. Treatment is needed to prevent worsening of the infection and serious illness.

How can you care for your child who has a perirectal abscess?

  • Have your child sit in a few inches of warm water (sitz bath) 3 times a day and after bowel movements. The warm water helps with pain and itching.
  • Be safe with medicines. Read and follow all instructions on the label.
    • If the doctor gave your child prescription medicine for pain, give it as prescribed.
    • If your child is not taking a prescription pain medicine, ask your doctor if your child can take an over-the-counter medicine.
  • If the doctor prescribed antibiotics for your child, give them as directed. Do not stop using them just because your child feels better. Your child needs to take the full course of antibiotics.
  • Have your child use stool softeners as directed.
  • Follow your doctor's instructions if your child was sent home with a drain or packing in the abscess.
  • Have your child avoid scented and colored toilet paper, which may irritate the anal area.
  • Help your child clean the area gently with wet cotton balls, a warm washcloth, or baby wipes.

Perirectal abscess in children: When to call

Call 911 anytime you think your child may need emergency care. For example, call if:

  • Your child has trouble breathing. Symptoms may include:
    • Using the belly muscles to breathe.
    • The chest sinking in or the nostrils flaring when your child struggles to breathe.
  • Your child is very sleepy and is hard to wake up.
  • Your child passes out (loses consciousness).

Call your doctor now or seek immediate medical care if:

  • Your child has symptoms of infection, such as:
    • Increased pain, swelling, warmth, or redness.
    • Red streaks leading from the area.
    • Pus draining from the area.
    • A fever.

Watch closely for changes in your child's health, and be sure to contact your doctor if:

  • Your child does not get better as expected.
