Many people because of unhealthy diet in life lead to anal fistula, and anal fistula after not timely treatment. Led to a series of complications, and we share the knowledge of anal fistula.

What is anal fistula

First of all, according to the position of fistula, this classification method is commonly used in medicine. (1) The lower anal fistula is located below the depth of the external sphincter. It can be divided into low simple anal fistula (only one fistula) and low complex anal fistula (with multiple fistulas and fistulas). (2) The high anal fistula is located above the depth of the external sphincter. It can be divided into high simple anal fistula (only one fistula) and high complex anal fistula (with multiple fistulas and fistulas).

Then according to the relationship between fistula and sphincter (1) anal sphincter type accounted for about 70% of anal fistula, mostly caused by perianal abscess. The fistula is located between the internal and external sphincter, the internal opening is near the dentate line, and the external opening is mostly near the anal margin. (2) Anal sphincter type accounted for about 25%, mostly caused by ischial anal space abscess, can be low or high anal fistula. The fistula passes through the external sphincter and ischiorectal space and opens on the perianal skin. (3) The upper anal sphincter type is a high anal fistula, which is rare, accounting for about 4%. The fistula extends upward between the sphincters, crosses the puborectal muscle, and penetrates the perianal skin through the ischiorectal space.

Finally, a small amount of purulent, bloody and mucinous secretions were repeatedly discharged from the external opening of anal fistula. Large high anal fistula, because the fistula is located outside the sphincter, not controlled by the sphincter, from time to time there will be feces and fart out.
