 More than 20 years have passed since EUS-BD was first reported in 2001, and EUS-BD is becoming a mature procedure. The process of EUS-BD involves first using a convex-type EUS scope to visualize the target bile duct, then securing a puncture line, checking for intervening blood vessels, and using an EUS-FNA needle to puncture, inject contrast media, and place a guide wire, after which the stomach and bile duct walls are dilated and a stent is placed. The most significant recent update has been the development of a convex-type EUS scope with EUS-BD in mind; and, with regard to EUS-HGS, it is now possible to perform B2 punctures safely and reliably from within the stomach. There is a wide variety of guidewires available, so it is now possible to choose the best guidewire for the situation. It is also now possible to safely and reliably dilate the gastric wall and bile duct wall thanks to the development of various devices. We are now in an age where metal stents, which did not exist 10 years ago, are covered by insurance and sold for EUS-BD. However, it is still important to carefully consider the indications and whether or not the case is one where EUS-BD should really be performed. No matter how much the devices have developed, it is absolutely essential to avoid using them incorrectly in cases where they are not indicated. Furthermore, the development of devices is progressing at an incredible speed, so EUS-BD biliary-pancreatic endoscopists must always keep their antennae up and continue to update their knowledge in order to perform EUS-BD in ways that are as reliable and safe as possible.
