Anal Fistula An anal fistula is commonly known as Fistula-in-ano as it is frequently the result of a previous or current anal abscess. An anal abscess is an infected cavity filled with pus found near the anus or rectum. The fistula is the tunnel that structures under the skin and interfaces the stopped up infected organs to a abscess. A fistula can be available with or without an abscess and may join just to the skin of the buttocks near the anal opening. Microscopic organisms, fecal material or foreign matter can obstruct a butt-centric organ and passage into the tissue around the anul or rectum, where it might then gather in a cavity called an abscess.
Anal Fistula is classified by two categories.1) By their location in relation to the structures comprising and surrounding the anus and rectum. on this basis, it is subclassified as perianal, ischioanal, intersphincteric and supralevator area. 2) By their relationship to parts of the anal sphincter complex: They are subclassified as intersphincteric, transsphincteric, suprasphincteric and extrasphincteric. Anorectal pain, swelling, perianal cellulitis (redness of the skin) and fever are the most common symptoms of an abscess. Occasionally, rectal bleeding or urinary symptoms, such as trouble initiating a urinary stream or painful urination, may be present.
Presently, there is no medicinal treatment accessible for this issue and surgery is quite often important to cure an anal fistula. On the off chance that the fistula is direct (including negligible sphincter muscle), a fistulotomy may be performed. The surgery may be performed in the meantime as waste of a abscess, once in a while the fistula doesn't show up until weeks or years after the starting drainage. Fibrin glue injection is one such alternative, in which fibrin glue is infused into the fistula tract to decimate the tract with the expectation of getting to be joined in the encompassing tissue.
First German S3 guideline for the treatment of cryptoglandular anal fistula. It includes recommendations for the diagnostic evaluation and treatment of this clinical entity. With an incidence of around 2 per 10 000 head of population per year, anal fistula is a frequent condition with a peak incidence between 30 and 50 years of age. Men are affected more often than women.
