What Is Anal Disorder?
i. Anal fissure ~ An anal fissure, also called an anorectal fissure, is a linear crack or tear in the skin of the anus. Most anal fissures happen when a large, hard stool overstretches the anal opening and tears the delicate anal skin. Less often, anal fissures develop because of prolonged diarrhea, inflammatory bowel disease or sexually transmitted diseases involving the anorectal area. Acute (short-term) anal fissures are usually fairly superficial and shallow, but chronic (long-term) anal fissures may extend deeper through the anal skin to expose the surface of underlying muscle.
ii. Anal abscess ~ An anal abscess is a tight, painful pocket of pus near the anus. Most anal abscesses are not related to other health problems and arise spontaneously, probably when bacteria or intestinal debris contaminate an anal gland, creating a site of infection under the skin. Currently in the United States, more than half of all anal abscesses occur in young adults between the ages of 20 and 40, and men are affected more often than women. Most anal abscesses are located near the opening of the anus but they can occur deeper and higher in the anal canal, closer to the lower colon or pelvic organs.
iii. Anal fistula ~ An anal fistula is an abnormal, narrow, tunnel-like passageway that connects the remains of an old anal abscess to the surface of the skin. Anal fistulas develop in about half of all anal abscesses that have drained. Sometimes, the opening of the fistula at the skin surface leaks a thick, foul-smelling liquid that has traveled from the depths of the old abscess. In other cases, the opening of the fistula eventually becomes plugged with draining debris, causing the old anal abscess to flare up again as a firm pocket of pus.
iv. Anal stricture ~ An anal stricture is a tight band of scar tissue that constricts the anal opening, interfering with the ability to pass stool comfortably. Anal strictures can be caused by radiation treatment for cancers located near the anal area, some sexually transmitted diseases, direct trauma to the anus or, rarely, surgery to remove hemorrhoids.
