“…Endoanal ultrasound (EAUS) allows imaging of the anal canal including the sphincter musculature and the surrounding tissues [2,3,4,5]. It is feasible to visualize the internal and external sphincter as well as to define pathologic situations such as sphincter defects, perianal abscesses, fistulas and anal cancer [2,6,7] EAUS is characterized by high sensitivity and specificity [6].…”

Background: Imaging of the anorectal region has drastically changed over the past decade by the introduction of anal endosonography. This method has been used to localize injuries to the anal sphincters, fistula tracts and abscesses as well as to assess local invasion of cancerous lesions. It allows a quick and easy visualisation of the anorectal mucosa and the surrounding muscular structures. Limitations of endosonography include strictures and acute painful conditions.These caveats are largely caused by the size of regular rectal probes with an average diameter of 17 to 20 mm.
