title: [Anal fissure].
abstract: Anal fissure is one of the very frequent and painful proctologic diseases. Linear ulcer is situated in the anal canal and extending from the dentate line to the margin of the anus. Fissure can cause pain and bleeding. Diagnosis is made from the history and local inspection. Acute anal fissure should be treated conservatively - increased fibre and fluid intake, warm baths, local anaesthetic ointment, alternatively with nitrates and if all else fails by botulinum toxin. Treatment of chronic fissure will start conservatively but operative options are necessary in many cases.
