   Fissure in ano  Glossary
Anus : The opening at the end of the digestive tract where bowel contents leave the body. Anal mucosa : Inner lining of anus. Anal spasm : Tightening or tension in the anus. Anal warts : Anal wart is a viral condition (caused by human papilloma virus). They first appear as tiny blemishes, perhaps as small as the head of a pin, and may grow larger than the size of a pea. Anorectal cancer : Cancer affecting rectum and anus. Anorectal fistula : Anorectal fistula is a hollow tract (opening) leading from the anal canal or rectum to the skin through which watery pus drains. Crohn’s disease : Crohn's disease is a chronic inflammatory process primarily involving the intestinal tract. It most commonly affects the last part of the small intestine (ileum) and/or the large intestine (colon and rectum). Also called as regional enteritis and ileitis. Hemorrhoids (piles) : Hemorrhoids are swollen, dilated veins of the rectum or anus. Hemorrhoids may be located at the beginning of the anal canal (internal hemorrhoids), or at the anal opening (external hemorrhoids). Hypertrophied anal papillae : Hypertrophied anal papillae are essentially skin tags that project up from the dentate line (the junction between the skin and the epithelial lining of the anus). They are often found as part of the classic triad of a chronic fissure, which includes the hypertrophied papilla above, the fissure, and a skin tag below (sentinal pile). Ischemia : Less blood supply. Lateral : On the sides. Perianal abscess : Perianal abscess is a collection of pus outside the anus. Pilonidal cyst : A pilonidal cyst or sinus is an abscess (localized collection of pus) or a chronic draining sinus (canal or passage leading to an abscess) located in the opening between the buttock muscles. This cyst may have a deep cavity containing hair and may be without symptoms unless it becomes infected. Posterior : Backside of given object. Rectal polyp : Polyps are stalk-like tumors or outgrowths in the rectum. Sentinal pile : It looks like small skin tag and actually is a vein that has dropped down from inside of the anus to lie outside. Ulcerative colitis : Ulcerative colitis is an inflammation of the lining of the large bowel (colon). |
