The investigation of neonatal obstructive jaundice using 123I rose bengal
Insights
Diagnosing infant jaundice is crucial for timely biliary atresia treatment. 123I-labelled rose bengal reliably identifies biliary patency, distinguishing biliary atresia from neonatal hepatitis.
Area of Science:
- Pediatric Gastroenterology
- Nuclear Medicine
- Diagnostic Imaging
Background:
- Biliary atresia requires prompt surgical intervention for improved infant outcomes.
- Differentiating biliary atresia from neonatal hepatitis is challenging due to overlapping clinical and histological features.
- Radiopharmaceutical tracers are established for demonstrating biliary patency, but optimal agents remain debated.
Purpose of the Study:
- To evaluate the efficacy of 123I-labelled rose bengal in diagnosing neonatal obstructive jaundice.
- To compare the diagnostic accuracy of 123I-rose bengal with previous agents for biliary patency assessment.
Main Methods:
- Nine infants with prolonged jaundice were studied.
- 123I-labelled rose bengal was administered to assess biliary patency.
- Diagnostic accuracy was determined by comparing imaging results with confirmed diagnoses.
Main Results:
- 123I-labelled rose bengal correctly identified all cases of biliary atresia.
- Neonatal hepatitis cases were also accurately distinguished.
- The tracer demonstrated reliable assessment of biliary patency.
Conclusions:
- 123I-labelled rose bengal is a reliable radiopharmaceutical for evaluating biliary patency in infants.
- It is the preferred agent for investigating neonatal obstructive jaundice, aiding in prompt diagnosis and intervention.
Abstract:
With the development of new surgical techniques the outlook for infants with biliary atresia has improved significantly. It has therefore become increasingly important to identify these patients quickly in order to allow prompt surgical intervention. Differentiation of biliary atresia from other causes of jaundice, in particular idiopathic neonatal hepatitis, is often difficult as there is considerable clinical and histological overlap of the two conditions. Demonstration of biliary patency using radiopharmaceuticals is a well established technique. 131I rose bengal and the 99Tcm-labelled iminodiacetic acid derivatives have both been used, but are not completely satisfactory, and controversy still exists as to which is the most suitable agent. Nine infants with prolonged jaundice have been studied using 123I-labelled rose bengal. All infants with biliary atresia and neonatal hepatitis were correctly identified. The results indicate that 123I rose bengal provides a reliable tracer for assessing biliary patency and is the agent of choice in the investigation of neonatal obstructive jaundice.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
