Background and study aimsLiver biopsy remains the most reliable method to diagnose various hepatic disorders in children. We aimed to assess the technical success and complication rate of ultrasound (US) assisted percutaneous liver biopsy versus transthoracic percussion guided technique in paediatrics.Patients and methodsThis randomized controlled study included all cases performing liver biopsy at Paediatric Hepatology Unit, Cairo University Paediatric Hospital over 12months.ResultsPatients were 102 cases; 62 were males, with age range 18days to 12years. Fifty seven procedures were done using the percussion guided technique and 45 cases were US assisted. The total number of complicated biopsies was 14 (13.7%), with more serious complications occurring in the percussion group. Complications were more frequent with younger age, lower platelet count, number of passes and occurrence of hypotension.ConclusionUS assisted percutaneous liver biopsy, although more costly, but may be safer to perform particularly in younger age.
