Anal fistula, closure with Anal Fistula Plug® (AFP®) - general and visceral surgery

Verify the indication by probing the fistula, then sparingly excise the external opening of the fistula. Follow this by flushing the fistula tract.

Insert a stay suture. Pull the tapered end of the AFP attached to the stay suture into the tract through the internal opening and the tract to the outside. Keep the plug under slight tension until it is firmly seated in the lumen of the fistula. Trim the internal excess such that the plug is flush with the mucosa.
