Paediatric liver biopsies: A single-centre experience in Erzincan Binali Yıldırım University.

Abstract

Introduction: Liver biopsies are the main method in the diagnosis and treatment of paediatric liver pathologies. Major complication rates of paediatric liver biopsies range from 0% to 6.6% in the literature and minor complication rates range from 0% to 25%. In this study, we aimed to review the complications, indications and results of percutaneous core liver biopsies with paediatric sonography in a tertiary care centre by an interventional radiologist.

Methods: We retrospectively evaluated the results, indications and complications of paediatric liver biopsies performed in our tertiary health centre between January 2017 and December 2020. Biopsies were performed with a 16G semi-automatic needle in 17 patients (29.8%) and with an 18G semi-automatic needle in 40 patients (70.2%). Biopsies were performed only with local anaesthesia in patients older than 12 years; in younger patients, it was performed under general anaesthesia.

Results: Fifty-eight liver biopsies were obtained from 57 children (34 males, 23 females). The most common indications were elevated liver enzymes (33 patients), cholestasis (14 patients), and adiposity and metabolic problems (6 patents). The most common pathological diagnoses were chronic hepatitis (33 patients) and steatosis (10 patients). Major complication in the form of symptomatic subcapsular haematoma developed after liver biopsy performed with 18G needle in only one patient (1.8%).

Conclusions: As previously stated in the literature, percutaneous biopsies performed by interventional radiologists in paediatric patients under the guidance of sonography can be used in diagnosis and treatment; the complication rate is low and it is a safe method.
