An infection that originates in the anal gland is the main cause of Anal Fistulas. An abscess is the outcome of the infection, and it either drains naturally or requires surgical draining through the skin adjacent to the anus. The tube that develops beneath the skin along this drainage route is called a fistula. The anal gland or anal canal is connected to the tunnel by a hole in the outer skin around the anus.
Sphincter muscle rings at the anus opening provide you control over how much stool comes out. The participation of these sphincter muscles helps classify fistulas. The surgeon can choose a course of treatment with the aid of this classification.
Risk factors
- drained anal abscess previously
- An inflammatory bowel disease, such as Crohn’s disease
- injury to the anal region
- infections in the region of the anus
- Radiation therapy or surgery for anal cancer
Anal fistulas typically affect adults over 40, while they can also affect younger people, particularly if they have a history of Crohn’s disease. Males are more likely than females to have anal fistulas.
