The most common cause of pain and bleeding during defecation is anal fissure, also called anal tear or anal fissure. This is the name given to a longitudinal tear in the transition zone of the tender skin of the anal canal (anoderm) to the outer skin. Anal fissure is one of the most common reasons why patients consult a proctologist.
Anal fissure is almost always a benign condition that is easily treated. The exact frequency is not known, because according to a representative survey, 87.5 % of people with anorectal complaints never see a doctor. Women seem to be affected slightly more often.
A distinction is made between the acute and the chronic form. Depending on the stage, conservative or surgical treatment methods are used.
