What is an anal fissure?
A fissure is a longitudinal tear in the lining of the lower anal canal, usually caused by a hard or bulky stool. The classic symptom is sharp, tearing pain during a bowel motion followed by a burning ache that can last for hours, often with a streak of bright red blood on the paper.
Most acute fissures heal within a few weeks with stool softeners, a high-fiber diet, warm sitz baths and a topical agent that relaxes the sphincter. A fissure that has been present beyond six to eight weeks is called chronic, and by then it usually has a fibrous base and a sentinel skin tag. Chronic fissures rarely heal on medication alone and are the ones considered for a procedure.
Assessed before any treatment is recommended.
