Anal Fistula and Anal Fissures

An anal fissure is a thin tear that stretches out from the muscles that control the rear-end (sphincters) up into the anal canal. These tears as a rule create when anal tissue is harmed during a hard solid discharge or when higher-than-typical strain creates in the anal sphincters.

An anal fistula is a tubelike entry (tract) from the anal canal to a gap in the skin close to the rear-end. This may happen after a rectal medical procedure, after a canker in the rectal territory, or as a confusion of an entrail infection.
