摘      要：AIM:To investigate whether flexible spectral color enhancement(FICE) improves diagnostic yields of capsule endoscopy(CE) for obscure gastro-intestinal bleeding(OGIB).METHODS:The study subjects consisted of 81 *** FICE,there were three different sets with different *** randomly selected sets of FICE,images of CE were evaluated again by two individuals who were not shown the conventional CE reports and *** difference between FICE and conventional imaging was ***:The overall diagnostic yields in FICE sets 1,2,3 and conventional imaging(48.1%) were 51.9%,40.7%,51.9% and 48.1%,respectively,which showed no statistical difference compared to conventional *** total numbers of detected lesions per examination in FICE imaging and conventional imaging were 2.5 ± 2.1 and 1.8 ± 1.7,respectively,which showed a significant difference(P = 0.01).CONCLUSION:The diagnostic yield for OGIB is not improved by ***,FICE can detect significantly more small bowel lesions compared to conventional imaging.
