Safety and diagnostic accuracy of ultrasound-assisted percutaneous liver biopsy in pediatric patients: a retrospective single-center study.

The mean patient age was 8.6 years (range 1 month to 17 years), with weights from 2.9-65 kg.

Indications included persistent hypertransaminasemia, cholestasis, autoimmune and metabolic liver disease, and post-transplant evaluation.

Histopathology revealed autoimmune hepatitis (autoimmune hepatitis) in 38.3%, autoimmune hepatitis with primary sclerosing cholangitis in 13.3% of patients with inflammatory bowel disease, and other diagnoses in the remainder.

No major complications or postprocedural bleeding occurred.
