Today, let’s discuss some facts on another common causes of per rectal bleeding- that is Fissure in ano (Also called Anal Fissure).
An anal fissure (fissure-in-ano) is a small, oval shaped break in skin that lines the opening of the anus. Fissures usually cause severe pain and bleeding with bowel movements. So, the main differentiating feature from Piles is presence of pain and type of bleeding. It commonly appears on the posterior(back) mid-line of anus.
A hard-dry stool is mainly responsible. But loose stool or diarrhea also can cause the same. The injury to the anus produces severe anal pain, resulting in spasm of anal sphincter followed by increase in anal sphincter muscle pressure. The increase in anal sphincter muscle pressure results in a decrease in blood flow to the site of the injury, thus impairing healing of the wound.
The majority of anal fissure patients don’t require surgery. The principle of treatment is to make stool well formed by increasing fiber content in diet or by supplementing as medications. Different ointments are available to reduce the pain and enhance healing of the fissure. Surgery is required in patients that don’t get relief on medications. Most common mode of surgery is division of a portion of anal sphincter. Complete healing of the anal fissure usually takes around 6-8 weeks (both medical and surgical management), but the severe pain disappears in few days after surgery. We should maintain high fiber intake and plenty of liquids regularly in our diet to prevent such ailment.
