Endoscopy remains the examination of choice in the evaluation of activity in Crohn's Disease (CD) after surgery (ADC-AS). However, digestive wall’s ultrasound (US-DW) may represent a non-invasive alternative. The objective of this study was to determine the diagnostic accuracy and concordance of this modality comparatively to endoscopy.
Cross-sectional study, comprising a period of 14 months, carried out in patients with established CD and ileocaecal resection due to the disease. Performed US-DW (HI-VISION avius®, Tokyo, Japan) with linear probe B-mode/Doppler prior to ileocolonoscopy. US-DW and colonoscopy were performed on the same day by 2 specialists in gastroenterology dedicated to ultrasound and inflammatory bowel disease, in a double-blind mode. Collected demographic and clinical data [Harvey–Bradshaw index (HBI, remission: ≤4)], serological/faecal inflammatory parameters [leucocytes (4 <
Included 39 patients (female: 64.1%, mean age: 43.5 ± 15.3 years). Surgery performed, on average, 5.3 ± 5.3 years after diagnosis. Mean post-surgery follow-up: 9.9 ± 6.9 years. Montreal classification: L1 61.5% (
The ultrasound evaluation of the digestive wall showed a good diagnostic accuracy and a good concordance with endoscopic, superior to clinical and inflammatory parameters.
