Background: Anal endosonography (AES) has become an essential part of the pre-operative diagnostic workup in both organic and functional anal diseases. Methods: Nine Italian centres with an average volume activity of >10 exams/week each were surveyed with the aim of determining the concordance with respect to indications for the procedure and interpretation of the results. Results: Overall, anal sepsis, faecal incontinence and anorectal tumours were the more common indications for AES while evacuation dysfunctions and anal pain were not always considered indications. All centres use the same diagnostic criteria for simple and complicated perirectal sepsis and sphincteric defects, but adopt different classifications for stage 1 and stage 2 anal tumours. Participants agreed in that lymph-node staging by AES is less precise than tumour staging, especially after chemoradiation therapy. Conclusions: A list of recommendations and guidelines based on the groups's experience has been produced for those radiologists and coloproctologists interested in the use of AES and accreditation of their centres. © 2007 Springer-Verlag.

Abstract
Background: Anal endosonography (AES) has become an essential part of the pre-operative diagnostic workup in both organic and functional anal diseases. Methods: Nine Italian centres with an average volume activity of >10 exams/week each were surveyed with the aim of determining the concordance with respect to indications for the procedure and interpretation of the results. Results: Overall, anal sepsis, faecal incontinence and anorectal tumours were the more common indications for AES while evacuation dysfunctions and anal pain were not always considered indications. All centres use the same diagnostic criteria for simple and complicated perirectal sepsis and sphincteric defects, but adopt different classifications for stage 1 and stage 2 anal tumours. Participants agreed in that lymph-node staging by AES is less precise than tumour staging, especially after chemoradiation therapy. Conclusions: A list of recommendations and guidelines based on the groups's experience has been produced for those radiologists and coloproctologists interested in the use of AES and accreditation of their centres. © 2007 Springer-Verlag.
