An anal fistula is a small tunnel under the skin that connects the abscess to the infected sebaceous gland. With symptoms of pain and a lot of pus discharge, the patient is uncomfortable. Currently, the main treatment for this disease is surgery.

Anorectal fistula is a pathology formed from abscesses near the anus (accounting for 50%). The cause is often due to blockage of sebaceous glands, which over time causes infection, abscess formation and gradually forms a fistula if not diagnosed and treated. Magnetic resonance imaging is an effective diagnostic tool in determining the fistula and the location of deep abscesses.

Magnetic resonance imaging is a method to evaluate and classify anal fistula. Magnetic resonance imaging has many advantages in accurately describing the anal anatomical area, assessing the relationship between the fistula and the pelvic diaphragm and rectal fossa. This is an important method to help doctors analyze and provide results for treatment.

If anal fistula is not treated promptly, it will cause many complications for the patient. The evaluation of anal fistula by imaging tests plays an important role in diagnosis as well as supporting treatment.
