Abstract
In the preoperative work-up of patients with anorectal fistulas, 3D-EAUS may represent the first-line diagnostic tool, showing high diagnostic accuracy in the evaluation of internal openings, primary tracks and secondary extension. In the cases of fistulas classified as complex by 3D-EAUS, MRI may be indicated as adjunctive diagnostic imaging examination, to more accurately detect the fistulas' secondary extensions, and so, to more carefully describe the fistulas' complete anatomy.
Keywords: 3D-EAUS; Anal fistula; Endoanal ultrasound; Magnetic resonance imaging; Perianal sepsis.
