[Diagnosis and principles of treatment for fissure in ano]
Abstract:
The diagnosis of an anal fissure can be made definitively on the basis of history and inspection. Therapy aims to stop the vicious circle of increased resting pressure, decreased perfusion, pain and obstipation. Chronic fissures are complicated by an incomplete fistula-in-ano. It is treated by laying open the fistula and sphincterotomy.
