Abstract:
OBJECTIVETo compare the diagnostic value study the technique of ultrasonography, magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) in common duct stones.
METHODSThree hundreds and eighty-four patients suspected common duct stones from August 2005 to October 2007 were undergone abdominal ultrasonography, MRCP and ERCP.
RESULTSThere was stone in common duct in 370 and no stones in 14 of 384 patients. Ultrasonography indicated stones 268 cases, 8 false positive result was among them. MRCP diagnosed stones in 362 cases and false positive result in 6 cases, ERCP diagnosed stones 370 cases. The diagnostic accuracy of ultrasonography, MRCP and ERCP was 70.3% (260/370), 96.2% (356/370) and 100% respectively.
CONCLUSIONSThe diagnostic accuracy of ultrasonography for common duct stone was little higher, US should be used as a primary checking method. There was higher concordance between MRCP and ERCP for common duct stone. Combination of MRCP and ERCP can improve diagnostic accuracy of common duct stone.
