Core Tip	In this retrospective cohort study, ultrasound-guided percutaneous transhepatic biliary drainage performed without fluoroscopy demonstrated a low rate of clinically significant bleeding (1.3%). Bleeding or vascular complications were primarily associated with procedural difficulty, including multiple needle passes and longer procedure time, as well as anatomical factors such as smaller target-duct diameter. Choledocholithiasis was also strongly associated with increased risk. These findings support the safety and feasibility of ultrasound-guided percutaneous transhepatic biliary drainage in resource-limited settings and highlight key technical factors that may help reduce bleeding complications.
