Expertise and rankings


Mayo Clinic surgeons have extensive experience with anal fistula, treating more than 700 people every year.

Leading-edge diagnosis and treatment

Mapping the fistula tracts and identifying internal openings can be difficult, especially for severe cases. Mayo Clinic specialists use state-of-the-art imaging technology to trace the pathways of anal fistulas, including endoscopic ultrasound, fistulography, magnetic resonance imaging (MRI) and flexible sigmoidoscopy.

Mayo Clinic doctors offer the latest treatment therapies to help eradicate anal fistula while preserving healthy tissue and normal function. Treatment options include seton placement, fibrin glue and ligation of the intersphincteric fistula tract (LIFT) for complex anal fistula, as well as standard fistulotomy.
