An anal fistula is usually caused by an infection near your back passage anus that causes a collection of pus abscess in the nearby tissue. When the pus drains away, it can leave a small channel fistula behind. An anal fistula may also be associated with certain long-term bowel conditions. An anal fistula is a small channel that develops between the end of the bowel and the skin near your back-passage anus. Most anal fistulas develop after an anal abscess.
Anal fistula symptoms and treatment - Patient | Patient
Anal fistula is the medical term for an infected tunnel that develops between the skin and the muscular opening at the end of the digestive tract anus. Most anal fistulas are the result of an infection that starts in an anal gland. This infection results in an abscess that drains spontaneously or is drained surgically through the skin next to the anus. The fistula then forms a tunnel under the skin and connects with the infected gland.
