Abstract:
The safety of percutaneous liver biopsy with a 1.2 mm Menghini needle in infants aged one year or less was investigated. One hundred and eighty four procedures performed from 1975 to 1985 were reviewed. There were no deaths or major complications within 48 hours associated with the procedure. In five instances specific complications occurred: a drop in haemoglobin concentration (three), transient hypotension (one), and haematoma at the biopsy site (one). The result of liver biopsy was diagnostic in 83% of cases, compatible with unspecified metabolic disease in 8%, and normal or not diagnostic in 9%. This study suggests that percutaneous liver biopsy can be performed with relative safety in small infants if coagulation is normal and there are no major contraindications, and the results yield important diagnostic information which cannot be obtained using less invasive procedures.
Insights
Percutaneous liver biopsy using a 1.2 mm Menghini needle is safe for infants under one year. This procedure provides crucial diagnostic information for pediatric liver conditions.
Area of Science:
- Pediatric Gastroenterology
- Hepatology
- Interventional Radiology
Background:
- Liver biopsy is essential for diagnosing pediatric liver diseases.
- Assessing the safety and efficacy of minimally invasive biopsy techniques in infants is critical.
Purpose of the Study:
- To evaluate the safety and diagnostic yield of percutaneous liver biopsy in infants aged one year or less.
- To determine complication rates and diagnostic accuracy using a 1.2 mm Menghini needle.
Main Methods:
- Retrospective review of 184 percutaneous liver biopsies performed between 1975 and 1985.
- Analysis of immediate complications (within 48 hours) and diagnostic outcomes.
Main Results:
- No deaths or major complications occurred within 48 hours post-procedure.
- Minor complications included hemoglobin drop (3), transient hypotension (1), and hematoma (1).
- Biopsy results were diagnostic in 83% of cases, aiding in the diagnosis of pediatric liver conditions.
Conclusions:
- Percutaneous liver biopsy with a 1.2 mm Menghini needle is a relatively safe procedure for infants with normal coagulation.
- The diagnostic yield is high, providing essential information for pediatric liver disease management.
- This minimally invasive approach offers valuable diagnostic insights when less invasive methods are insufficient.
