What is Perianal Abscess?

Perianal abscess is an infective condition around the anus. This condition usually starts as a small pimple-like papule which gradually enlarged into a firm nodule or swelling.

You may experience some pain or discomfort as the pressure builds up and some people may even develop a fever.

Why Does Perianal Abscess Occur?

The reason for such a condition is multifactorial ranging from a blocked gland on the skin to an inflammatory bowel condition known as Chron's disease. T

he presence of diabetes or an immune-compromised state can aggravate this problem.

How to Treat Perianal Abscess?

Treatment of perianal abscess can be as simple as a course of antibiotics. This is generally effective in killing the bacteria within a small abscess.

However, larger ones may require specific treatment including surgical drainage. Besides treating the abscess, knowing the predisposing factors, and addressing them will help to prevent abscess from recurring.

How to differentiate piles from fistulae or perianal abscesses as the real cause for pain and swelling near the anus?

The best way to determine the cause of pain and swelling near the anus is to examine the anus region. Swollen and painful piles appear at the edge of the anus while perianal abscesses and fistulae are found at least 1 cm away from the edge of the anus. If your family doctor is unsure whether you have piles or abscess, he/she will usually refer you to a colorectal surgeon to confirm the diagnosis.

What tests can help to distinguish between a pile, abscess or fistula?

A painful lump in the anus can be due to piles, abscess or even anal fissure. The most important assessment is by examination of the anus and rectum. This is performed in the clinic with digital rectal exam (using a finger) as well as inserting a short anal probe (less than 7cm deep) to see the inside of the anus. This should be sufficient to confirm the diagnosis. In rare circumstances, if the clinical exam is not able to confirm the diagnosis, your doctor may request for an ultrasound or MRI.
