WHAT IS AN ANAL FISSURE?
An anal fissure is a small tear or cut in the skin that lines the anus. Fissures typically cause pain and often bleed. Fissures are quite common, but are often confused with other causes of pain and bleeding, such as hemorrhoids.
WHAT ARE THE SYMPTOMS OF AN ANAL FISSURE?
The typical symptoms of an anal fissure are pain during or after defecation and bleeding. Patients may try to avoid defecation because of the pain.
WHAT CAUSES AN ANAL FISSURE?
Trauma: anything that can cut or irritate the inner lining of the anus can cause a fissure. A hard, dry bowel movement is typically responsible for a fissure. Other causes of a fissure include diarrhea or inflammatory conditions of the anal area. Anal fissures may be acute (recent onset) or chronic (present for a long time or recurring frequently). Chronic fissures often have a small external lump associated with the tear called a sentinel pile or skin tag.
