Anorectal endosonography is established as a diagnostic tool in anorectal f
istulas, today. Yet, there is still little experience with the use of this
method in small children. We could visualize three intershincteric fistulas
in children at an age of 6, 7 and 14 months. The procedure is well tolerat
ed and even children under the age of one year can be examined with a speci
al probe.
