An anal fistula is an abnormal tunnel-like tract that develops between the anal canal and the skin around the anus. It usually occurs as a result of an infection or abscess near the anal region. Anal fistulas can cause persistent pain, swelling, pus discharge, and recurrent infections if not treated properly.
Diagnosis involves a detailed medical history, physical examination, and specialized proctological assessment. Imaging studies such as MRI Fistulogram, Endoanal Ultrasound, or CT scans may be advised to determine the fistula's course and complexity before treatment planning.
Many people often confuse a fistula with a fissure because both conditions affect the anal region and can cause pain and discomfort. However, they are different medical conditions. An anal fissure is a small tear in the lining of the anus that commonly causes pain during bowel movements and bleeding. If left untreated, chronic anal conditions may lead to complications that require specialized treatment. If you are experiencing symptoms such as severe pain, burning sensation, or bleeding while passing stools, it is important to seek timely care.
