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

Abstract

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.
