anal fissure

Sometimes called fissure-in-ano, this is a longitudinal tear in the wall of the anus, usually directly backwards. There is inevitable infection and a swollen skin tag, called a sentinel pile forms at the site. There is burning pain on defaecation. Surgical treatment is effective but about 10 per cent of patients suffer anal incontinence, mainly for flatus. BOTULINUM TOXIN has been used.
