Percutaneous transhepatic biliary drainage (PTBD) and cholangitis have complex relationships, with cholangitis sometimes complicating biliary drainage procedures. This review critically examines these correlations and discusses prevention strategies for septic complications.

Area of Science:

  • Medical Imaging
  • Interventional Radiology
  • Hepatology

Context:

  • Percutaneous transhepatic biliary drainage (PTBD) is a crucial intervention for biliary obstruction.
  • Cholangitis, an inflammation of the bile ducts, presents a complex relationship with PTBD, sometimes arising as a complication.
  • Understanding these correlations is vital for effective patient management.

Purpose:

  • To critically review the clinical and radiological correlations between cholangitis and PTBD.
  • To explore various pathogenetic hypotheses of cholangitis, including inflammation and cholestasis.
  • To identify risk factors associated with cholangitis in patients undergoing PTBD.

Summary:

  • The relationship between PTBD and cholangitis is multifaceted, with cholangitis potentially complicating the drainage procedure.

  • Pathogenetic factors such as inflammation, cholestasis, and surgical manipulation contribute to cholangitis.
  • Risk factors include impaired immune function, immunosuppression, extensive liver involvement, multiple ductal obstructions, chronic liver disease, and advanced age.

    • Impact:

    • Provides a clinical-radiological perspective on PTBD-cholangitis interactions.
    • Highlights key risk factors to guide preventative measures.
    • Informs strategies for preventing and treating septic complications, including chemoprophylaxis and targeted antibiotic therapy.
