Abstract
Endoanal ultrasound, using specific ultrasound criteria, H2O2 injection and 3D reconstructions, allows accurately defining the topography of the fistula tract and its relationship with the anal sphincters, detecting secondary extensions and furnishing information regarding the existence of anal sphincter defects before surgery. All this information is critical to reducing the risk of septic recurrence and post-operative faecal incontinence. In expert hands, it also plays an important part in the assessment of complex, Crohn-related and recurrent fistulas.
