title: Transpapillary selective bile duct cannulation technique: Review of Japanese randomized controlled trials since 2010 and an overview of clinical results in precut sphincterotomy since 2004.
abstract: In 1970, a Japanese group reported the first use of endoscopic retrograde cholangiopancreatography (ERCP), which is now carried out worldwide. Selective bile duct cannulation is a mandatory technique for diagnostic and therapeutic ERCP. Development of the endoscope and other devices has contributed to the extended use of ERCP, which has become a basic procedure to diagnose and treat pancreaticobiliary diseases. Various techniques related to selective bile duct cannulation have been widely applied. Although the classical contrast medium injection cannulation technique remains valuable, use of wire-guided cannulation has expanded since the early 2000s, and the technique is now widely carried out in the USA and Europe. Endoscopists must pay particular attention to a patient's condition and make an attendant choice about the most effective technique for selective bile duct cannulation. Some techniques have the potential to shorten procedure time and reduce the incidence of adverse events, particularly post-ERCP pancreatitis. However, a great deal of experience is required and endoscopists must be skilled in a variety of techniques. Although the development of the transpapillary biliary cannulation approach is remarkable, it is important to note that, to date, there have been no reports of transpapillary cannulation preventing post-ERCP pancreatitis. In the present article, selective bile duct cannulation techniques in the context of recent Japanese randomized controlled trials and cases of precut sphincterotomy are reviewed and discussed.
