METHODS: Six hundred and ninety-one consecutive CE procedures collected in a database were analyzed. SBTT and CE findings were recorded. A running mean for the SBl-I- was calculated and correlated to the diagnostic yield with a Spearman's correlation test. Subgroup anal- yses were performed for the various indications for the procedure. RESULTS: There was a positive correlation between the diagnostic yield and SBT1- (Spearman's rho 0.58, P 〈 0.01). Positive correlations between diagnostic yield and SB-FI-were found for the indication obscure gastro- intestinal bleeding (r = 0.54, P 〈 0.01), for polyposis and carcinoid combined (r = 0.56, P 〈 0.01) and for the other indications (r = 0.90, P 〈0.01), but not for suspected Crohn's disease (r = -0.40) CONCLUSION: The diagnostic yield in small bowel capsule endoscopy is positively correlated with the small bowel transit time. This is true for all indications except for suspected Crohn's disease.展开更多
