			| Anal Fissure and FistulaAn
		anal fissure is a narrow tear that extends from the
		muscles that control the anus (sphincters) up into the anal canal. These tears
		usually develop when anal tissue is damaged during a hard bowel movement or
		when higher-than-normal tension develops in the anal sphincters. An anal fistula is a tubelike passage (tract) from
		the anal canal to a hole in the skin near the anus. This may occur after rectal
		surgery, after an abscess in the rectal area, or as a complication of a bowel
		disease. ByHealthwise StaffPrimary Medical ReviewerAnne C. Poinier, MD - Internal Medicine
