Percutaneous biliary drainage (PBD) offers palliative relief for high biliary obstruction. This involves transhepatic approaches, anesthesia, and careful consideration of long-term drainage options and potential complications.

Area of Science:

  • Interventional Radiology
  • Gastroenterology
  • Oncology

Background:

  • High biliary obstruction necessitates palliative drainage.
  • Bifurcational obstructions require expertise in both right and left transhepatic approaches.
  • PBD is the preferred method for managing these obstructions.

Purpose of the Study:

  • To outline the preferred techniques for percutaneous biliary drainage (PBD).
  • To discuss anesthesia considerations for transhepatic tract dilatation.
  • To review choices for long-term biliary drainage and follow-up care.

Main Methods:

  • Right transhepatic approach guided by fluoroscopy.
  • Left transhepatic approach guided by ultrasonography.
  • Use of large caliber drainage catheters and tract dilatation.

Main Results:

  • Anesthesia, particularly epidural, is crucial for managing pain during tract dilatation.
  • Long-term drainage involves choosing between internal-external catheters and endoprostheses.
  • Interventional radiologists play a key role in patient follow-up and complication management.

Conclusions:

  • Successful PBD requires familiarity with dual transhepatic approaches and appropriate guidance.
  • Pain management and patient factors are critical for long-term drainage success.
  • Interventional radiologists are integral to the comprehensive management of patients undergoing PBD.
