Abstract:
Objective To compare the effect of endoscopic ultrasonography (EUS),magnetic resonance chlangiopancreatography (MRCP) and endoscopic retrograde cholangiography (ERCP) in the diagnosis of suspicious intermediate choledocholithiasis.Methods One hundred and eighty-six patients with suspicious intermediate of choledocholithiasis successively received MRCP,EUS,and ERCP examination.The stone taking out by endoscopic as diagnositic standard,and the sensitivity,specificity and accuracy in different methods was compared.Results Sensitivity and accuracy of EUS was significantly higher than that of MRCP [97.5％(155/159) vs.92.5％(147/159),97.3％(181/186) vs.91.9％(171/186)](x2 =4.21,5.30,P =0.04,0.02).There was no statistically significant difference between EUS and ERCP in specificity [96.3％(26/27) vs.88.9％ (24/27)] (x2 =115.40,P ＜ 0.05).Sensitivity,specificity and accuracy of ERCP was 98.9％(184/186),98.7％(157/159) and 100.0％(27/27),and there was no difference between EUS and ERCP in the diagnosis of choledocholithiasis (P ＞ 0.05).Conclusions EUS is similar with ERCP for the diagnosis of choledocholithiasis.By performing EUS or MRCP first,ERCP may be avoided in patients with suspicious intermediate choledocholithiasis.
