Fecal calprotectin (FC) has drawn attention as a biomarker in the evaluation of Crohn's disease (CD). However, few reports have provided a detailed examination of the relationship between small-bowel CD lesions and FC levels. The present study aimed to examine the entire small bowel using double-balloon endoscopy (DBE) and to determine the relationship between the endoscopic activity in small-bowel CD and FC levels. Twenty small-bowel CD patients, who underwent DBE, were prospectively enrolled. Endoscopic evaluation was based on the simple endoscopic score for CD, with the small bowel divided into four regions. This score was defined as the double-balloon endoscopic score for CD (DES-CD). Furthermore, to focus on mucosal membrane damage, we used the partial DES-CD (pDES-CD), in which presence of stenosis was excluded from DES-CD. DES-CD revealed a correlation with FC (γ = 0.691, P = 0.001) and C-reactive protein (CRP) (γ = 0.631, P = 0.003) levels. Furthermore, pDES-CD showed a correlation with the FC level (γ = 0.747, P &lt
0.001), erythrocyte sedimentation rate (γ = 0.492, P = 0.028), and the CRP level (γ = 0.605, P = 0.005). CD Activity Index and endoscopic score showed no correlation. Our results revealed a correlation between the endoscopic activity in small-bowel CD and FC levels. Furthermore, pDES-CD showed a strong correlation with FC levels. This may be because FC levels were elevated due to mucosal membrane damages, rather than stenoses.

Small bowel capsule endoscopy (SBCE) and balloon-assisted endoscopy (BAE) have revolutionized the diagnosis and treatment of small bowel bleeding (SBB), allowing access to the small bowel and identification of specific bleeding lesions. However, some patients experience rebleeding after small bowel investigation, and there are no definitive algorithms for determining the most appropriate follow-up strategy in SBB patients. We developed and validated a nomogram that can predict rebleeding risk and be used to develop a risk-stratified follow-up strategy in SBB patients. A retrospective study was performed using data from 401 SBB patients who underwent SBCE at Nagoya University Hospital. We developed and internally validated a predictive model for rebleeding in the form of a nomogram using Cox regression models and a bootstrap resampling procedure. Optimal risk factors were selected according to the least absolute shrinkage and selection operator (LASSO). The LASSO method identified 8 independent predictors of rebleeding that could be assessed to obtain a 'predicting rebleeding in SBB', or 'PRSBB' score: age, sex, SBB type, transfusion requirement, cardiovascular disease, liver cirrhosis, SBCE findings, and treatment. The c-statistic for the predictive model was 0.681. In conclusion, our PRSBB score can help clinicians devise appropriate follow-up plans.
