Abstract Anal fissure is a common disease of the anus. It is located posteriorly in most cases and usually occurs after a bout of constipation due to trauma by hard faeces. Chronicity occurs due to the spasm of the internal anal sphincter holding the discharge inside the floor of the fissure & leading to chronic infection. Usually, the patient with anal fissure presented by painful defecation and a skin tag at the anal orifice discribed by the patient as piles. Diagnosis of anal fissure depends on mainly on history & rectal digital examination. There are many methods for treatment of anal fissure which may be conservative or operative. Operations for treatment of chronic anal fissure are; anal dilatation, excision of the fissure and internal sphincterotomy. The aim of this work is to know the role of the internal anal sphincter in cases of chronic anal fissure. By measuring the anorectal pressure in 25 patients with anal fissure, we found that it is increased in coparision with the control group (25) and that it increased nearly to normal levels after internal sphincterotomy. |
