Book Your Consultation NowWhat Exactly is an Anal Fistula?
An anal fistula, medically known as 'fistula-in-ano,' is a small, unnatural tunnel that develops under the skin and connects an infected gland inside the anus (the exit point of the digestive tract) to an opening on the skin near the anus.
Think of it as a detour tunnel. It usually forms after an infection near the anus causes a collection of pus (an anal abscess). Once the abscess is drained, either naturally or surgically, the tunnel often remains, leading to chronic drainage and discomfort.
Primary Causes of Anal Fistula
The overwhelming majority of anal fistulas are caused by a preceding **anal abscess**. However, other factors can also lead to their formation:
- Infected Anal Glands: The most common cause. These tiny glands in the anal canal become blocked, leading to infection and abscess formation.
- Inflammatory Bowel Disease (IBD): Conditions like Crohn's disease can increase the risk of developing complex fistulas.
- Surgery or Trauma: Previous surgery in the anal area, or trauma, can sometimes result in a fistula.
- Infections: Less common causes include tuberculosis or HIV.
Key Symptoms: Know the Signs
If you experience any of these symptoms, especially persistent ones, it's crucial to consult a specialist immediately for effective **fistula treatment**.
- Persistent Pain: Throbbing or aching pain around the anus, which may worsen when sitting, moving, or having a bowel movement.
- Drainage/Discharge: Foul-smelling, bloody, or pus discharge from a small opening (the external opening) near the anus.
- Redness and Swelling: Inflammation and tenderness of the skin around the anal area.
- Fever and Chills: Sometimes associated with acute infection or an active abscess.
- Skin Irritation: Itching or irritation of the perianal skin due to persistent drainage.
Accurate Diagnosis: The Path to Treatment
Diagnosis of an anal fistula is typically straightforward but requires a skilled specialist to map the tunnel correctly.
- Physical Examination: The doctor will examine the area, often finding the external opening and looking for signs of drainage or tenderness.
- Probing the Fistula: A small probe may be gently inserted into the external opening to determine the tunnel's length and direction.
- Imaging Tests (MRI/Ultrasound): For complex fistulas or to rule out other conditions, an MRI or endorectal ultrasound may be used to provide a clear, detailed map of the tunnel's path, crucial for planning surgery.
- Anoscopy: A small instrument is used to view the inside of the anal canal to locate the internal opening.
