About Rectal abscess (pus collection)

The rectum is the last part of the large intestine attaching to the anus. An abscess is a collection of pus. A rectal abscess (also called `perirectal` abscess can form around the edge of the anal opening or deeper into the rectum. This condition is more often found in men and in people with digestive diseases.

Symptoms

Pain in the rectal area, discharge of pus from the rectum, lump or nodule, swelling, redness, fever, pain associated with bowel movements, constipation. Sometimes the abscess drains through an opening in the skin. This can cause moisture or soiling of underwear.

Tests & Diagnostics

A history and physical exam will be performed including a rectal examination (the doctor needs to feel inside the rectum to find the tender area). At times a CT scan and/or a more detailed examination of the rectum called `proctosigmoidoscopy` is done to determine the size and extent of the abscess.

Common tests: Complete blood count (CBC), CT Scan.

Conventional treatment summary

Incision and drainage is the treatment of choice. Large abscesses may require surgery. Antibiotics may be administered for extending redness around the abscess.
