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

Doctor's Answers 1

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.

How long does it take to heal after undergoing perianal abscess drainage?

A perianal abscess wound healing time will depend on the size of the abscess cavity as well as whether the abscess is associated with an anal fistula. Generally, an abscess that is smaller than 2cm in size heals within 2-3 weeks. An abscess large than 5cm may take 4-6 weeks to heal. It is important to wash your buttocks frequently to keep the area clean. Cleaning yourself with water (such as using the shower spray) after bowel movement helps keep the wound clean from faeces. That is important to allow the wound to heal quickly.
