Comparison of gastrointestinal ultrasound with capsule endoscopy in patients with small bowel Crohn's Disease.

The results of our study revealed that the SUS-CD had an area under the curve (AUC) of 0.90 (95% confidence interval) with P<0.05, as determined by the ROC analysis. Moreover, the diagnostic accuracy of gastrointestinal ultrasound (GIUS) was 79.7%, with a sensitivity of 93.6%, and a specificity of 81.8% (P<0.05). GIUS exhibited a positive predictive value of 96.7%, a negative predictive value of 69.2%, and a confidence interval of 95% (P<0.05) in predicting CE disease. Furthermore, the agreement between GIUS and CE was assessed using Spearman's Correlation and SUS-CD with Lewis score (r = 0.82, P < 0.05.) CONCLUSION: To conclude, our findings demonstrate a strong correlation between gastrointestinal ultrasound and capsule endoscopy in assessing the disease activity in patients with Crohn's disease affecting the small intestine.
