title: [Clinical study of trans-T tube duodenal papilla balloon dilatation: a novel procedure for postsurgical residual common bile duct stone].
abstract: OBJECTIVE
  To investigate the safety and efficacy of trans-T tube duodenal papilla balloon dilatation for the removal of residual common bile duct stone after choledocholithotomy and T tube drainage.
  
  
  METHODS
  Thirteen cases with residual common bile duct stone treated with trans-T tube duodenal papilla balloon dilatation in our department from June 2010 to April 2012 were analyzed retrospectively. Record CA19-9, bilirubin and albumin before the procedure, 1 week and 1 month later. Check if immediate complications occurs, including hemorrhage, perforation, pancreatitis and cholangitis. During the following up for 2 years, stone recurrence, reflux cholangitis and other long-term complications were observed. Analyze the changes of indicators between preoperative and postoperative and the correlation.
  
  
  RESULTS
  All of the 13 patients were treated successfully. 11 patients underwent one procedure, and 2 patients received twice or more times of procedures. CA19-9 decreased significantly 1 week later and 1 month later compared with those before the procedure, while ALB was opposite. Incidences of biliary tract infection and hemorrhage were 1 and 1 respectively. No severe complications occurred, including perforation of gastrointestinal or biliary tract. Incidences of recurrent stone and reflux cholangeitis were 2 and 1 in two years after the procedure.
  
  
  CONCLUSIONS
  Trans-T tube duodenal papilla balloon dilatation is a safe and effective procedure for patients with recurrent common bile duct stone after choledocholithotomy and T-tube drainage. For the cases which could not be handled with endoscopic procedures, it provides a new therapeutic approach.
