Impact of a new scoring system on selection of endoscopic retrograde cholangiopancreatography or magnetic resonance cholangio-pancreatography prior to cholecystectomy in patients with suspected common bile duct stones

ABSTRACT

Background: Endoscopic retrograde cholangiopancreatography [ERCP] with stone extraction is the gold standard for the management of common bile duct [CBD] stones. Many scoring systems had developed aiming at prediction of CBD stones prior to cholecystectomy to avoid unnecessary ERCP. On the other hand Magnetic Resonance Cholangiopancreatography [MRCP] had proved efficiency in diagnosis of CBD stones and was replacing ERCP in some centers but with additional cost for therapeutic ERCP in case of CBD stones
