Abstract

Purpose The aim of this study was to evaluate the technical feasibility, complication rate, and efficacy of percutaneously delivered plastic biliary stent, compared with that of internal–external biliary drainage catheter.

Methods Patients with unresectable malignant biliary obstruction were included who underwent percutaneous transhepatic biliary drainage and double pigtail plastic stenting (DPT-PS) or internal–external biliary drainage catheter in 15 months' duration.

Results Seventy-seven patients were included in the study who underwent DPT-PS (n = 37) or internal external drainage catheter placement (n = 40). Overall, the technical success rate for percutaneous plastic stenting was 92.5% and technical success rate for primary stenting at the time of initial puncture was 62%. The incidence of fever and hemobilia was similar across the two groups, whereas bile leakage in the perihepatic space and through the skin at puncture site was higher in patients with internal–external drainage catheter. Both the techniques were effective in reducing the bilirubin levels of patients. Re-intervention was done in five patients in DPT-PS and six patients with ring biliary catheter.

Conclusion DPT-PS may be used as a viable cost-efficient alternative for unresectable biliary malignancies with low post-procedure life expectancy.
