Endorectal ultrasound (ERUS) has become a basic tool for the diagnosis and staging of many proctologic and pelvic floor disorders.

The procedure is done by the use of an ultrasound and a rectal probe, specially design to explore the rectoanal area.

This procedure is useful in many different situations:

  • Rectoanal diseases such as perianal fistula, perianal abcess, Crohn´s disease etc.


  • Rectal tumor staging


  • Fecal incontinence. By ERUS we can visualize defects in the anal sphincters.


  • Other situations such us anal pain etc.
