Haemorrhoids (Piles)

Haemorrhoids (also known as piles) are swollen veins found in the lower rectum. They are abnormally engorged and swollen blood vessels in the anus and lower rectum, causing discomfort, itchiness or pain. In addition, they can swell up with blood clots (thrombosed piles), causing severe pain. A more dangerous complication of piles is rectal (or anal) bleeding.

They are also differentiated by their location; internal haemorrhoids and external haemorrhoids.

Internal haemorrhoids are usually painless but tend to lead to anal bleeding, while external haemorrhoids may cause pain.

Anal Fistula

An anal fistula is a small channel that makes an abnormal connection between the end of the bowel and the skin around the anus. More often than not, anal fistulas start from an infection near the anus that causes a collection of pus (abscess) in the surrounding tissue.

The collection of pus grows and stretches the skin through the lining of the anus. Thus a connection is formed between the skin and anus.

Surgery to drain the pus may also leave a small channel behind. This is known as an anal fistula, and it may cause anal bleeding and discharge when passing motion and can be painful.

In some instances, the abscess cannot heal, and tears open on the skin’s surface, resulting in a painful anal fistula. The most common and effective way to remove perianal abscess is via surgical incision and drainage.
