Percutaneous biliary endoscopy offers a valuable approach for interventional radiologists managing complex biliary diseases. This technique, applied via existing tracts, can reduce radiation exposure and aid in diagnosing and treating conditions like retained stones and lesions.

Area of Science:

  • Interventional Radiology
  • Gastroenterology
  • Endoscopic Procedures

Background:

  • Percutaneous biliary interventions are common procedures for managing various biliary diseases.
  • Biliary endoscopy can serve as an adjunct tool in these interventions.
  • Existing literature highlights the need for a comprehensive review of percutaneous biliary endoscopy.

Purpose of the Study:

  • To discuss the advantages, disadvantages, and applications of percutaneous biliary endoscopy in interventional radiology.
  • To provide technical advice, patient preparation guidelines, and information on potential complications.
  • To review the existing literature on the use of percutaneous biliary endoscopy for biliary diseases.

Main Methods:

  • Percutaneous biliary endoscopy is applied through established transhepatic or T-tube tracts.

  • The procedure is typically performed on an outpatient basis utilizing conscious sedation.
  • A choledochofiberscope is used, requiring operator familiarity for effective application.

    • Main Results:

    • Percutaneous biliary endoscopy can be applied to a wide range of biliary diseases, including retained intrahepatic stones and suspected lesions requiring biopsy.
    • The technique offers reduced radiation exposure for both patients and healthcare personnel.
    • It is a valuable tool for managing complex biliary disease, especially when other methods are challenging.

    Conclusions:

    • Percutaneous biliary endoscopy is a useful adjunct to percutaneous biliary interventions, despite technical and cost considerations.
    • Familiarity with the choledochofiberscope and its application enables interventional radiologists to effectively manage complex biliary conditions.
    • This endoscopic approach can be safely performed on an outpatient basis, offering significant benefits in specific patient populations.
