Understanding different classifications of anal fistulas and their implications.
The most common type, located between the internal and external sphincter muscles. Usually simple and easy to treat.
Passes through both sphincter muscles. May require more complex treatment to preserve continence.
Rare type that passes above the sphincter muscles. Often associated with Crohn's disease.
Very rare, passes outside the sphincter muscles. Usually results from trauma or surgery.
Simple fistulas are low-lying and straight, while complex fistulas are high-lying, curved, or involve multiple tracts.
Proper classification helps determine the most appropriate treatment approach and predicts the likelihood of complications.
