Misconceptions exist about the proper way to use draining setons in the management of anal fistulas. This technical note lays out the principles for their use.TECHNIQUE:
Insertion of draining setons is a prerequisite to successful management of anal fistulas. The correct technique involves identification of the correct track and internal opening and drainage of the track with a silastic seton. This sets the stage for definitive repair after the inflammation subsides.RESULTS:
Three cases are presented to illustrate common errors made during the insertion of draining setons.CONCLUSIONS:
Appropriate seton drainage of an anorectal fistula is an important part of the ultimate repair. Correct use of setons minimizes symptoms from the seton itself and optimizes its effectiveness.
