The Impact of Puncture Angle on Total Fluoroscopy Time Reduction During Percutaneous Biliary Drainage

The purpose of this study is to retrospectively assess the importance of initial bile duct puncture angle on total fluoroscopy time and overall efficacy during ultrasound and fluoroscopy guided percutaneous transhepatic biliary drainage (PTBD) performed for patients with malignant biliary hilar obstruction.

About this study

Data used for this study will be collected from medical records of patients who underwent PTBD at the Interventional radiology department. Only patients who received percutaneous biliary drainage performed with right sided intercostal approach will be included in study. The initial puncture was ultrasound-guided in all patients. Any subsequent step of the procedure was performed under fluoroscopy. The cumulative fluoroscopy time (the total time of the exposure to X rays during intervention) after the US guided puncture was recorded. It will be used as an indirect measure of the complexity of the intervention and as an important parameter of radiation exposure. The patients will be divided into two groups based on the puncture angle: ≤30° group and >30° group. The two groups will be retrospectively analysed for technical success, fluoroscopy time and complications.

Treatment and study plan

Percutaneous biliary drainage

Procedure

Primary outcomes

  1. Total fluoroscopy time

    Time frame: during intervention

    The initial puncture was ultrasound-guided in all patients. Any subsequent step of the procedure (PTBD) was performed under fluoroscopy. Total fluoroscopy time will be collected from Radiation Dose Report obtained in the angio suite workstation software ( General Electric Innova 540)
