Abstract

Purpose: To retrospectively assess the diagnostic performance of grey-scale ultrasound (US) characteristics and gamma-glutamyl transpeptidase (GGT) alone or combined in distinguishing biliary atresia (BA) from other cholestasis diseases in infants younger than 30 days.

Materials And Methods: Between January 2012 and October 2020, the demographic characteristics, laboratory results and US characteristics of 35 BA and 52 non-BA infants younger than 30 days were retrospectively evaluated. Areas under the receiver operating characteristic curves (AUCs) were used to estimate the probability of predicting BA, which were compared by DeLong test.

Results: The diagnostic performance of gallbladder classification in identifying BA was higher than that of fibrotic cord thickness (AUC 0.900 vs. 0.771, P = 0.03). With the cutoff level of 188 IU/L, serum GGT had a sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 77.1%, 69.2%, 62.8%, and 81.8%, respectively. Combined with gallbladder classification and GGT, the sensitivity, specificity, PPV, NPV and accuracy were 100.0%, 63.5%, 64.8%, 100.0% and 78.2%.

Conclusions: Gallbladder classification was more valuable than fibrotic cord thickness in the diagnosis of BA among infants less than 30 days. Combined with gallbladder classification and GGT, the sensitivity for the diagnosis of BA can reach 100.0%.
