Transjugular liver biopsy with an automated device

Area of Science:

• Hepatology
• Interventional Radiology
• Pathology

Background:

• Transjugular liver biopsy is an alternative when percutaneous biopsy is contraindicated.
• Conditions like thrombocytopenia, coagulopathy, and ascites pose risks for percutaneous biopsy.
• Automated biopsy devices offer potential for improved tissue acquisition.

Purpose of the Study:

• To evaluate the efficacy and safety of an automated device for transjugular liver biopsy.
• To determine if the automated device can obtain adequate tissue for histopathologic diagnosis.
• To assess the complication rate associated with automated transjugular liver biopsy.

Main Methods:

• Transjugular liver biopsy was performed using an 18-gauge automated device in 29 patients.
• Patients had liver dysfunction and contraindications for percutaneous transperitoneal biopsy.
• Histopathologic specimens were analyzed quantitatively and qualitatively for adequacy and diagnostic value.

Main Results:

• Adequate biopsy specimens (mean length 12.0 mm) were obtained in all patients with a single pass.
• Confident histopathologic diagnoses were achieved for all tissue samples.
• No complications were reported during the transjugular liver biopsy procedures.

Conclusions:

• Automated biopsy devices are suitable for transjugular liver biopsy.
• This technique ensures safe and effective acquisition of high-quality liver tissue.
• It provides a valuable option for patients unable to undergo percutaneous biopsy.
