OBJECTIVE
To investigate the safety and efficacy of percutaneous transhepatic balloon dilation for the removal of common bile duct stone.
METHODS
Sixty-eight cases with common bile duct stone treated with percutaneous transhepatic balloon dilation in our department from July 2008 to April 2011 were analyzed retrospectively.Record CA19-9, total bilirubin, indirect 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 68 patients were treated successfully.53 patients underwent one procedure, and 15 patients received twice or more times of procedures. CA19-9, TBIL and IBIL decreased significantly 1 week later and 1 month later compared with those before the procedure, while ALB was opposite.Incidences of biliary tract infection, hemorrhage, and pancreatitis were 4.4% (3/68), 2.9% (2/68) and 1.5% (1/68) respectively.No severe complications occurred, including perforation of gastrointestinal or biliary tract.Incidences of recurrent stone and reflux cholangitis were 14.7% (10/68) and 5.9% (4/68) in two years after the procedure.
CONCLUSIONS
Percutaneous transhepatic balloon dilation is a safe and effective procedure for patients with common bile duct stone. For the cases which could not be handled with endoscopic procedures, it provides a new therapeutic approach.
