Conditions
Brief summary
Endoscopic retrograde cholangiopancreatography (ERCP) is commonly performed to remove bile duct stones.Endoscopic sphincterotomy (EST), endoscopic papillary balloon dilation (EPBD), and endoscopic sphincterotomy plus balloon dilation (sEST+EPBD) are 3 methods used to enlarge the papillary orifice, but their efficacy and safety remains controversial. This study aimed to compare these methods for treating common bile duct (CBD) stones.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| the incidence of composite events of infection, hemorrhage, perforation, pancreatitis | 3 and 24 hours after the ERCP | Investigators comprehensively assess whether the hemorrhage, perforation, pancreatitis and other complications of retrograde cholangiopancreatography (ERCP) happen or not by clinical sympton and blood index 1 day after the ERCP. The blood index includes CRP, amylase,lipase,leukocyte,red blood cell,hemoglobin.Besides,CT will be done if necessary.Finally investigators use statistical method to analyse the incidence of composite events of infection, hemorrhage, perforation, pancreatitis. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Recurrence rate of bile duct stones | 1 year after the ERCP. | One year after the ERCP,the participants will have a CT scan to find out whether the bile duct stones recur again. |
