- 7. Treatment Aims • Eradicatedisease (if possible) • Preservation of continence • Benign condition • Quality of life
- 8. Principles • Control sepsis – EUA – Laying open abscesses and secondary tracts – Adequate drainage – seton insertion • Define anatomy – Openings and tracts • Internal and External • Single –v- multiple • Extensions / Horseshoe – Relation to sphincter complex • High –v- Low • Exclude co-existent disease

- 10. Surgical Options –Fistulotomy • Fistula tract identified with probe • Extent of external sphincter involvement assessed • Tract and muscle divided • Secondary tracts laid open • +/- marsupialisation wound
- 11. Surgical Options –Cutting Seton • Lay open external tract • Draining seton replaced with cutting seton • 1/0 Prolene suture • Tied tight around sphincter complex • Simultaneous slow cutting and repair of sphincter • May require re-tightening
- 12. Surgical Options –Fistulectomy • Draining seton • Core out tract • Direct visualisation of secondary tracts • Sphincter repair +/- advancement flap
- 13. Advancement Flaps Endorectal • Fistulatract probed • Flap raised – Mucosa + Int. Sphincter • Internal opening excised/closed • Flap advanced & sutured
- 14. Advancement Flap Anodermal • Fistulatract probed • Flap raised – Anodermal • Flap advanced & sutures • External defect closed
