AIM: To evaluate the correlation of grey-scale and colour Doppler sonography with colonoscopy and histology to detect bowel inflammation in children. MATERIAL AND METHODS: The records of 72 patients with suspected bowel inflammation were reviewed retrospectively. Patients were included in the study if sonography had been performed up to 30 days before colonoscopy. Greyscale and colour Doppler sonography were used to evaluate bowel wall thickness and vascularity for the detection of distal bowel inflammation. Findings were correlated with colonoscopy and histological findings. The sensitivity and specificity of sonographic wall thickness to detect inflammation was determined. Spearman's coefficient (rs)was used to determine the correlation of Doppler findings with cotonoscopy/histology. RESULTS: Sonograms of 372 bowel segments were evaluated and results were correlated with colonoscopy and histotogical findings of 352 segments. The sensitivity and specificity of sonographic bowel thickness to detect inflammation in the terminal ileum and the right colon were high; in the other segments, specificity was high but sensitivity was tow. The correlation of Doppler sonography with colonoscopy and histology to detect inflammation in the terminal ileum was strong (rs: 0.84; p < 0.001) and in the other segments, weak to moderate; when the interval between examinations was shorter than 10 days, the correlation was stronger in all segments. Of nine patients with abnormal small bowel sonograms but normal colonoscopies, three had Crohn's disease. CONCLUSION: Sensitivity and specificity of grey-scale sonography to detect inflammation in the terminal ileum and the right colon were high, and the correlation of Doppler with colonoscopy and histology was very strong in the same segments.
