The Decision-making Value of Magnetic Resonance Cholangiopancreatography in Patients Suspicious for Pancreatobiliary Diseases / 대한소화기학회지

ABSTRACT

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is an operator-dependent procedure and has significant procedure-related morbidity and mortality. Magnetic resonance cholangiopancreatography (MRCP) is a safe noninvasive method for pancreatobiliary imaging. The aims of this study were to evaluate the potential impact of MRCP on performing ERCP and to evaluate the decision-making value of MRCP in patients suspicious for pancreatobiliary diseases. METHODS: Two hundreds twelve patients (MF 108104, mean age 59.3+/-13.7) who underwent MRCP due to clinical or sonographic suggesting pancreatobiliary disease were included. We divided patients into four groups according to their presumptive diagnosis biliary stone (group 1), biliary tumor (group 2), gallstone pancreatitis (group 3) and other biliary diseases (group 4). RESULTS: Numbers of cases in group 1, 2, 3 and 4 were 145, 43, 17 and 7, respectively. In 144 cases (67.9%), ERCP was unnecessary and 76 cases (35.8%) required neither ERCP nor any other treatment. Thereafter, these cases were thought to be a patient group in whom the workload of performing ERCP could be reduced. CONCLUSIONS: MRCP can reduce the number and efforts doing ERCP and is helpful in decision-making for the treatment of pancreatobiliary disease. Therefore, MRCP could be the primary diagnostic tool before choosing ERCP.
