Endoanal Ultrasonographic Imaging of the Anorectal Region
摘要
Endoanal ultrasound imaging is the gold standard investigation for the assessment of the anorectal region. High-resolution 3D ultrasonography allows to evaluate in detail the anal sphincter anatomy enabling the practitioner to investigate patients with anal sphincter damage, perianal abscesses and fistulas, defecatory dysfunction, and anorectal pain.
