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 analyzed.SBTT and CE findings were recorded.A running mean for the SBTT was calculated and correlated to the diagnostic yield with a Spearman’s correlation test.Subgroup analyses were performed for the various indications for the procedure.RESULTS: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,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.

A: 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. S. BTT and CE findings were recorded. A running mean for the SBTT was calculated and correlated to the diagnostic yield with a Spearman’s correlation test. Subgroup analyzes were performed for the various indications for the procedure .RESULTS: 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, P <0.01), for polyposis and carcinoid combined (r = 0.56, P <0.01) and for the other indications = 0.90, P <0.01), but not for 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 fo r suspected Crohn’s disease.
