摘      要：AIM:To investigate whether the small bowel transit time(SBTT)influences the diagnostic yield of capsule endoscopy(CE).METHODS:Six hundred and ninety-one consecutive CE procedures collected in a database were *** and CE findings were recorded.A running mean for the SBTT was calculated and correlated to the diagnostic yield with a Spearman s correlation *** analyses were performed for the various indications for the ***:There was a positive correlation between the diagnostic yield and SBTT(Spearman s rho 0.58,P 0.01).Positive correlations between diagnostic yield and SBTT were found for the indication obscure gastrointestinal bleeding(r=0.54,P0.01),for polyposis and carcinoid combined(r=0.56,P0.01)and for the other indications(r=0.90,P0.01),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 *** is true for all indications except for suspected Crohn s disease.
