Aim: To assess the usefulness of rectal endosonography to detect invasive carcinoma and eventual lymph node involvement in villous adenomas. Material and methods: Retrospective review of 1400 rectal endosonographies performed between years 2000 and 2006. Those cases in which a rectal villous adenoma was informed, that were subjected to surgical excision and that had a pathology report were included in the study. Results:
