ABSTRACT Producing images similar to those acquired by the invasive procedures of endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangiography, magnetic resonance cholangiopancreatography (MRCP) is indicated in patients who are unable to undergo ERCP or have had previously unsuccessful ERCP. It is used increasingly in non-invasive evaluation of the pancreaticobiliary tree in cases where the need for intervention during ERCP is expected to be low. MRCP may help in identifying anomalous biliary anatomy or choledocholithiasis before laparoscopic cholecystectomy, and in deciding between percutaneous or endoscopic treatment for patients with obstructive jaundice to decrease the rate of failed ERCP procedures.

    ABSTRACT: Intraoperative cholangiography during laparoscopic cholecystectomy reveals the anatomy of the biliary tree and any stones contained within it. The use of intraoperative cholangiography may be routine for all laparoscopic cholecystectomy. An alternative approach is a selective policy, performing intraoperative cholangiography only for those cases in which choledocholithiasis is suspected on clinical grounds, or those for which the anatomy appears unclear at operation. The literature pertaining to both approaches is reviewed, to delineate their respective merits. Relevant articles in English were identified from the Medline database, and reviewed. The literature reviewed consisted of retrospective analyses. Overall the incidence of unsuspected retained stones was 4%, but only 15% of these would go on to cause clinical problems. The incidence of complete transection of the common bile duct was rare for both routine and selective intraoperative cholangiography policies, and did not differ between them. Rates of minor bile duct injury did not differ between groups, but was more likely to be recognized in the routine group than the selective (P = 0.01). Routine intraoperative cholangiography yields very little useful clinical information over and above that which is obtained with selective policies. Large numbers of unnecessary intraoperative cholangiography are performed under routine intraoperative cholangiography policy, and therefore a selective policy is advocated.
