Seton Placement in Anal Fistula Treatment

A seton is a soft thread passed through a fistula tract. It is used when protecting sphincter function is a priority, either to allow drainage or as part of a staged treatment plan.

When it is considered

Complex or high transsphincteric fistula tracts
Recurrent abscess formation
Fistula associated with inflammatory bowel disease
Situations where continence risk must be minimised

What to expect afterwards

Mild discomfort and ongoing drainage are expected while the seton is in place. Follow-up visits assess inflammation, tract maturation and the timing of the next treatment step.
