Classification (Parks’ Classification):

According to Parks’ classification, anal fistulas are categorized into four types:

1. Intersphincteric (54%) – Confined within the internal sphincter.

2. Trans-sphincteric (44%) – Extends through both internal and external sphincters.

3. Suprasphincteric (2%) – Passes above the puborectalis muscle and opens into the ischiorectal fossa.

4. Extrasphincteric (1%) – Bypasses the sphincter mechanism entirely and opens into the skin.

Investigation:

☢️MRI Fistulogram – Best modality to determine fistula tract anatomy.

☢️Endoanal Ultrasound – Useful for complex fistulas.

4. LIFT Procedure (Ligation of Intersphincteric Fistula Tract) – A sphincter-sparing technique.
