ABSTRACT
The objective is to explore the correlation between ultrasonic gallbladder length-width ratio (LTWR) and age, and the value of differential diagnosis between biliary atresia (BA) and other hepatic cholestasis. From January 2016 to June 2022, the data of 183 patients with jaundice who underwent abdominal ultrasound and surgical exploration in the Affiliated Hospital of Zunyi Medical University were analyzed retrospectively. The demographic data, liver function, and ultrasonic parameters were recorded and analyzed. There were statistically significant differences between BA group and non-BA group in maximum length, maximum width and LTWR of gallbladder (P < 0.001). In all age groups (I: ≤ 30 days; II: 31-60 days; III: 61-90 days; IV: 91-120 days; V: ≥ 121 days), in which group III (61-90 days) had the highest area under the curve (AUC) of 0.843, and group V (≥121 days) had the lowest AUC of 0.548. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of gallbladder LTWR > 3.26 for BA in group II (31-60 days) were 78.9%, 75.0%, 75.0%, 78.9% and 76.9%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of gallbladder LTWR > 3.69 for BA in group III (61-90 days) were 76.6%, 84.6%, 92.5%, 59.5% and 78.9%, respectively. Ultrasonography LTWR of gallbladder has certain value in the diagnosis of BA. The diagnostic value of gallbladder LTWR in infants with different ages was quite different, and it was relatively high in infants with 31-90 days.
