Investigators first divided the patients with different sizes of common bile duct stones into two groups. The bile duct stone diameter of group A is less than 1.0cm while group B is more than 1.0cm and less than 1.5cm. Each group compared Endoscopic sphincterotomy (EST), endoscopic papillary balloon dilation (EPBD), and endoscopic sphincterotomy plus balloon dilation (sEST+EPBD) in ERCP. Through the postoperative comparison of relevant inspection test indicators, the recovery of patients, whether the occurrence of complications, including infection,bleeding,pancreatitis,perforation , and 1 year stone recurrence rate,Investigators assess the advantages and disadvantages in three different strategies in different sizes of common bile duct stones , and finally get a relatively objective evaluation to guide our daily ERCP work on the choice of duodenal papillary sphincter treatment strategy.
