[0002] Biliary stones are a common bile duct disease in my country. With the increase in the incidence of gallstones, the incidence of extrahepatic bile duct stones secondary to gallstones falling into the bile duct has also increased significantly. Biliary stones are mainly treated through endoscopic retrograde cholangiopancreatography (ERCP) or surgery. Because ERCP is minimally invasive and has a fast recovery, it has become the main method for treating bile duct stones. During ERCP, a guide wire is first inserted into the bile duct through the duodenal papilla, and the location and size of the stone are determined by angiography. The uninflated stone removal balloon catheter is sent into the bile duct along the guide wire, and the tip of the stone removal balloon catheter is passed over the stone site, and then inflated to form a balloon to fill and occupy the bile duct, and then the inflated stone removal balloon is used to drag the stone out of the bile duct.
