Fistula tract curettage and the use of biological dermal plugs improve high transsphincteric fistula healing in an animal model

Purpose The treatment of high transsphincteric fistula is a complex procedure, which may be associated with the risk of recurrence and fecal incontinence. In this study, we used an animal model to compare different types of sphincter-preserving treatments for transsphincteric fistula.
