Abstract
Among the endoscopic interventional therapies that are available for pancreatobiliary diseases, endoscopic nasobiliary drainage (ENBD) is fundamental, since it does not require any devices or additional techniques other than a guide-wire, a drainage tube and ordinary cannulation. Furthermore, this procedure is very useful and effective for emergencies, especially for obstructive jaundice. In this paper, the basic skills needed for this procedure are documented mainly for beginners, as supervised by an expert doctor. The most important key to successful treatment is to keep a short distance between the papilla and tip of the endoscope throughout the procedure. In addition, the papilla and biliary tract should be treated very gently and carefully. Furthermore, while keeping the advantages and disadvantages of this technique in mind, appropriate management of ENBD is still required.
