A comparison between endoscopic retrograde and magnetic resonance cholangiopancreatography for the diagnosis of pancreaticobiliary diseases / 中国微创外科杂志

ABSTRACT

Objective To determine how endoscopic retrograde cholangiopancreatography (ERCP) compared with magnetic resonance cholangiopancreatography (MRCP) in the diagnosis of pancreaticobiliary diseases. Methods A total of 40 patients with suspected pancreaticobiliary diseases underwent both MRCP and ERCP. Images obtained from ERCP and MRCP were compared. Results Pictures of both the examinations in the 40 patients had come out satisfactorily revealing the pancreatic duct and the biliary tree. The sensitivity, specificity and accuracy were 87% (34/39), 100% (1/1) and 88% (35/40) in MRCP and 100% (39/39), 100% (1/1) and 100% (40/40) in ERCP, respectively, without significant differences between the two examinations. Conclusions Although MRCP offers a diagnostic means equivalent to ERCP, it cannot take the place of the latter as regards identification of biliary obstruction.
