Brief Summary

Endoscopic retrograde cholangiopancreatography (ERCP) has become one of the most important techniques in the treatment of bile duct stones. A number of studies have been conducted using large-balloon dilation (LBD) after adequate EST to extract large bile duct stones. In those studies, the authors suggested that EST plus LBD might lower the risk of post procedure pancreatitis (PEP) by directing balloon dilation toward the bile duct rather than the pancreatic duct. It has been reported that EPBD followed by insertion of nasobiliary drainage catheter can prevent PEP. However, it is still unclear that nasobiliary drainage after endoscopic sphincterotomy plus large-balloon dilation for preventing postoperative pancreatitis in treating of large bile duct stones.The investigators therefore designed a prospective randomized trial to determine whether nasobiliary drainage prevent PEP after endoscopic sphincterotomy plus LBD for the treatment of large bile duct stones.

Outcome Measures

Primary Outcomes (1)

  • The prophylaxis effect of ENBD on post-ERCP pancreatitis after endoscopic sphincterotomy plus LBD for the treatment of large bile duct stones.

    If the serum amylase of patients elevation and 3 times higher than the normal values after ERCP 24 hours in high risk patients, who also have clinical symptoms, without other acute abdominal diseases,such as gastrointestinal perforation,acute cholecystitia and acute cholangitis and etc. In this condition, it will be defined PEP(post-ERCP pancreatitis). Descriptive statistics will be produced for all continuous variables. Frequency tables of number (N) and percentage of subjects will be produced for all categorical variables.

    the incidence of post-ERCP pancreatitis at 24 h after ERCP in two groups

Secondary Outcomes (1)

  • Compare EST+LBD+ENBD group EST+LBD with group on the incidence of hyperamylasemia/adverse events.

    the incidence of hyperamylasemia/adverse events at 24 h after ERCP in two groups
