An anal fistula is an abnormal tube-like connection that forms between the inside of the anus at the anal gland and the skin right outside the anus. Think of it as a tunnel. The abscess that causes the fistula is quite painful.
Anal fistula is a chronic abnormal communication between the epithelialised surface of the anal canal and usually the perianal skin. They can form when anal abscesses do not heal properly. Anal fistulae originate from the anal glandswhich are located between the internal and external anal sphincter and drain into the anal canal.
An anal abscess is an infected cavity filled with pus found near the anus or rectum. Ninety percent of abscesses are the result of an acute infection in the internal glands of the anus. Occasionally, bacteria, fecal material or foreign matter can clog an anal gland and tunnel into the tissue around the anus or rectum, where it may then collect in a cavity called an abscess.
Perianal fistula is characterized by chronic, purulent, malodorous, ulcerating, sinus tracts in the perianal tissues. It is most common in German Shepherds and is also seen in Setters and Retrievers. The cause is unknown, although many theories have been proposed. Contamination of the hair follicles and glands of the anal area by fecal material and anal sac secretions may result in necrosis, ulceration, and chronic inflammation of the perianal skin and tissues.
A perianal fistula is a painful opening in the skin around the anus of a dog. The condition affects German Shepherds most commonly, although other breeds can develop the problem. There are several possible contributing factors, including genetics, allergic skin disease, and alterations in immune system functioning.
Most anal fistulas form in reaction to an anal gland that has developed a pus-filled infection abscess. Even if your abscess drains on its own, you have about the same risk for a fistula. Certain conditions that affect your lower digestive tract or anal area may also increase your risk.
An anorectal or anal fistula is an abnormal, infected, tunnel-like passageway that forms from an infected anal gland. Sometimes an anal fistula works its way from an internal gland to the outside of the skin surrounding the anus. On the skin, this looks like an open boil.
It is claimed that finding the internal orifice of anal abscess to distract the corresponding anal gland duct; will decline the rate of future anal fistula. Surgeons supporting I and D alone claim that finding the internal opening is hazardous. This study is conducted to assess short-term results of optional method to manage patients with anal abscess and fitula-in-ano at the same time. Once the opening was distinguished, an incision was given from the anal verge to the internal opening.
The anus is that part of the intestinal tract that passes through the muscular canal of the pelvis and anal sphincters. It is the final orifice through which stool passes out of the body. In adults, the anus is 4 to 5 centimeters long.
