Rectal Fistula Treatment Options: Surgical Procedures & Recovery

Surgical Management of Anal Fistula

Persistent or complex fistulas require surgery. Procedure choice balances healing rate vs. sphincter preservation (continence).

Procedures by Complexity

1. Fistulotomy (Lay Open):
   • Incise fistula tract → heals by secondary intention.
   • Best for low, simple fistulas with minimal sphincter involvement.
   • High success (90%+); low incontinence risk if <30% external sphincter divided.
2. Fistulectomy:
   • Excise entire tract + internal opening.
   • Primary or secondary closure.
   • Higher success than fistulotomy but more tissue loss; avoid if sphincter involved.
3. LIFT (Ligation of Intersphincteric Fistula Tract):
   • Identify tract in intersphincteric plane; ligate and close internal opening.
   • Sphincter-sparing; success 60–95%.
   • Preferred for transsphincteric fistulas.
4. Advancement Flap (Mucosal/Dermal):
   • Mobilize healthy tissue to cover internal opening.
   • Sphincter-sparing; for complex/high fistulas.
   • Success 70–90%; risk of flap failure.
5. Seton Drainage (Staged):
   • Silicone/silk loop through tract → promotes fibrosis, controls sepsis.
   • Precursor to definitive repair (LIFT, flap) or long-term palliative.
6. Novel: VAAFT, FiLaC, OTSC—endoscopic/laser/clipping; emerging data.

Post-Op Care

• Sitz baths, stool softeners, analgesics.
• Follow-up for wound healing, continence assessment.
