226 The Liberal Use of Magnetic Resonance Cholangiopancreatography (MRCP) can be switched over to its Selective use to detect choledocholithiasis

Abstract

Abstract Gallstone disease is known in 10-15% of adults in Western populations. Cholangiopancreatography (MRCP) is the investigation of choice for choledocholithiasis; however, its use is varied, and guidelines are not well defined. The National Institute for Health and Care (NICE) guidelines recommends MRCP to be done when common bile duct (CBD) dilatation ≥ 8mm or liver function tests (LFTs) are abnormal but do not quantify this further. The liberal use of magnetic resonance cholangiopancreatography (MRCP) is gaining popularity as a roadmap prior to cholecystectomy, aiming to assess primarily for the presence of migrated gallstones within the cystic duct or common bile duct, as well as providing information regarding the anatomical features of the extrahepatic biliary tree on an individualised basis .Due to these reasons MRCP’s at times are done unnecessarily which creates economic burden and restricts access to patients in real need of imaging slots The aim of this retrospective study was to identify whether magnetic resonance cholangiopancreatography (MRCP) can be used selectively in patients with deranged liver enzymes with gallstone disease to detect choledocholithiasis, based on liver function tests (LFTs) and ultrasonography appearance.
