Value of endoscopic ultrasonography in the assessment of inflammatory bowel diseases.

The value of EUS in the assessment of inflammatory bowel diseases was determined. EUS was useful for estimation of the histological changes of inflammatory bowel diseases. In ulcerative colitis, EUS findings were classified into five types, which correlated with the colonoscopic and histological findings. Studies in surgical cases and further prospective investigations are necessary, however, to determine whether EUS can contribute to the management of inflammatory bowel diseases.
