Abstract
Nearly 50 years have passed since the first report of endoscopic retrograde cholangiography. Ever since, endoscopic retrograde cholangiopancreatography (ERCP) have been a basic procedure for practice in pancreatico-biliary diseases. Of the various procedures of ERCP, selective biliary cannulation is the most basic and important technique. Various cannulation techniques have been reported with the development of endoscopes and devices. However, there still does not exist the perfect technique that enables selective biliary cannulation for whichever cases. Although contrast medium injection cannulation technique is important, wire-guided cannulation technique has been extended and is now widely performed since early 2000s in the US and Europe. We should use various techniques to achieve safe, accurate and effective bile duct cannulation with a shorter procedure time and reduced complications. Nowadays, recent development of bile duct cannulation, especially transpapillary approach, is discussed in this report.
