Percutaneous transhepatic papillary ballooning and extraction for common bile duct stones: a single-center experience.

BACKGROUND

At present, some common bile duct stones (CBDSs) cannot be removed by conventional endoscopic treatment. Percutaneous transhepatic papillary ballooning and extraction (PTPBE) is a promising treatment for CBDSs. This study aimed to evaluate the feasibility and efficacy of PTPBE for removing CBDSs.

METHODS

From April 2013 to April 2021, 29 patients with CBDSs underwent PTPBE at The First Affiliated Hospital of Zhengzhou University; their clinical data were retrospectively analyzed. The technical success, clinical success, procedure time, radiation dose, 1-year CBDSs recurrence rate, and incidence of early/late complications were recorded, and white blood cell (WBC) counts and alanine aminotransferase (ALT), C-reactive protein (CRP), total bilirubin (TBIL), and carbohydrate antigen-199 (CA-199) levels were compared before the interventional procedure and 1 month later.

RESULTS

The CBDSs were successfully removed in 29 patients (the CBDSs in 20 patients were resolved once, and in 9 patients, they were resolved twice). The mean procedure time and radiation dose were 56.38±13.56 minutes and 732.07±262.23 miligray (mGy), respectively. The technical and clinical success rates were both 100%. The incidence of early complications (including pancreatitis and bile duct bleeding) and late complications (reflux cholangitis) was 10.34% and 3.45%, respectively. The WBC (both P<0.01), ALT (both P<0.01), CRP (both P<0.01), CA-199 (both P<0.01), and TBIL (both P<0.01) significantly decreased before PTPBE and 1 month later.

CONCLUSIONS

PTPBE is a safe and effective alternative solution for elderly patients who cannot undergo or refuse traditional surgical and endoscopic treatments.
