  • Objective To investigate the value of endoscopic ultrasound( EUS) versus magnetic resonance cholangiopancreatography( MRCP) in the diagnosis of obstructive jaundice. Methods A total of 31 patients with obstructive jaundice who visited Beijing Tiantan Hospital,Capital Medical University,from January 2015 to March 2016 were enrolled,and all the patients underwent EUS and MRCP. The sensitivity,specificity,accuracy,and Youden index of EUS and MRCP in the diagnosis of obstructive jaundice were compared. Results Of all patients,16( 51. 61%) were diagnosed with common bile duct stones,1( 3. 23%) was diagnosed with ampullary tumor,6( 19. 35%)were diagnosed with duodenal papillary tumor,3( 9. 68%) were diagnosed with tumor of the head of the pancreas,2( 6. 45%) were diagnosed with bile duct tumor,2( 6. 45%) were diagnosed with bile duct inflammation,and 1 had no stones or space- occupying lesions observed by endoscopic retrograde cholangiopancreatography,EUS,or MRCP. The coincidence rate of EUS in the diagnosis of ampullary tumor,duodenal papillary tumor,and tumor of the head of the pancreas was 100%,and MRCP had a lower coincidence rate in the diagnosis of common bile duct stones and a lower overall coincidence rate of diagnosis than EUS( 81. 25%/76. 67% vs 93. 75%/90. 00%). In the diagnosis of obstructive jaundice,EUS and MRCP had sensitivities of 90. 00% and 76. 70%,specificities of 100%,accuracy rates of 90. 30% and77. 40%,and Youden indices of 0. 90 and 0. 77. Conclusion EUS has a higher value in the diagnosis of obstructive jaundice than MRCP.
