Summary
Percutaneous transhepatic liver biopsy with tract embolization (PBTE) yields high-quality diagnostic specimens. However, complications were observed, particularly in patients with coagulopathy and less experienced operators.
Area of Science:
- Hepatology
- Interventional Radiology
- Gastroenterology
Background:
- Percutaneous liver biopsy is crucial for diagnosing diffuse liver diseases.
- Patients with coagulopathy or ascites present increased risks for standard liver biopsy.
- Tract embolization aims to mitigate bleeding risks after liver biopsy.
Purpose of the Study:
- To evaluate the efficacy and safety of percutaneous transhepatic liver biopsy with tract embolization (PBTE).
- To assess PBTE in patients with increased bleeding risk due to coagulopathy or ascites.
Main Methods:
- Eighty PBTE procedures were performed in 76 patients with diffuse liver disease.
- Patients included those with coagulopathy, ascites, or both.
- A cutting needle and gelatin sponge for embolization were utilized.
Main Results:
- All biopsy specimens (100%) were adequate for histopathologic diagnosis.
- A complication rate of 8% was observed, including bleeding, bowel injury, and hemobilia.
- Complications were associated with coagulopathy and operator inexperience.
Conclusions:
- PBTE is an effective method for obtaining diagnostic liver biopsy specimens.
- The complication rate appears linked to patient coagulopathy and operator experience.
- Further refinement in technique may improve safety profiles for PBTE.
