Betamethasone in plus phenobarbitone prior to hepatobiliary scintigraphy increases diagnostic accuracy in infants with jaundice

Abstract

Objective: In the diagnostic work up of the child with neonatal obstructive cholangiopathy (NOC), hepatobiliary scintigraphy (HBS) determines the need for peroperative cholangiography (POC). Traditionally, phenobarbitone is recommended to prime the liver to HBS. This retrospective study was designed to evaluate whether addition of the betamethasone (BM) alters the diagnostic accuracy of the HBS in distinguishing neonatal hepatitis (NH) from extra hepatic biliary atresia (EHBA).

Methods: Between 1993-1999, 202 patients presented with NOC and this study was not designed as a prospective randomized clinical trial. Of these, 126 patients had received Phenobarbitone (Group I) and the remaining 76 (Group II) had received BM in addition to the PB in a dose of 5 mg/k/d and 2.2 mg/k/d respectively for 7 days prior to HBS.

Results: Retrospective analysis revealed that, in the Group I, 41 showed excretion and 85 did not show any excretion of the radiopharmaceutical and the latter underwent POC which revealed that 31 patients (36%) of them showed patent biliary tract. In group II, 32 patients revealed excretion and 44 did not show any excretion of the radiopharmaceutical and the latter had undergone POC, which revealed that only 8 patients (18%) showed patent biliary tract. The percentages of false positives (36% vs 18%) was statistically significant (p < 0.03).

Conclusion: Addition of BM increases the diagnostic accuracy of the HBS and this would lead to decreased need for POC to distinguish NH from EHBA.
