“…Biliary atresia is a congenital biliary disorder, commonly causing progressive and obstructive pathological changes in the intra and extrahepatic ducts, secondary to inflammation, and often causing progressive fibrosis and liver damage, resulting in cirrhosis of the liver and consequent liver failure [2,3,4,5] It is characterized by absence or severe deficiency of the extra-hepatic biliary tree [6], and accounts for over half of children who undergo liver transplantation [5]. It is thought to affect 1 in 10,000 -15,000 newborn infants, with a recognized male preponderance [3,5].…”

“…Prompt and accurate diagnosis is essential for early operative intervention, efficient treatment and a good prognosis to prevent liver cirrhosis in such neonates [5,6]. To aid the diagnosis of biliary atresia, an abdominal ultrasound and hepatobiliary iminodiacetic acid (HIDA) scan may be used [6].…”

“…Several investigators have described the Triangular Cord sign (TC) as a useful and specific ultrasound (USS) finding for the differential diagnosis of biliary atresia from neonatal hepatitis [7]. There are some evidences that TC sign, i.e triangular structure located cranial to the portal vein bifurcation on ultrasonographic examination, is suggestive of biliary atresia (BA) in suspected cases [6]. Imanieh et al [6] concluded in their study, that TC sign is more accurate than hepatobiliary scan and has acceptable sensitivity and specificity for diagnosis of BA.…”

Objectives-The aim of this study was to evaluate the influence of fasting time on the ultrasound identification and exclusion of biliary atresia in jaundiced infants through the use of the gallbladder classification scheme and to test the value of the gallbladder classification scheme in the diagnosis of biliary atresia in inexperienced individuals.Methods-A total of 188 jaundiced infants were enrolled in this study. All patients received detailed abdominal sonograms. Diagnoses were confirmed via liver biopsy, surgical findings, or follow-up. Infants were grouped into either the fasting group (fasting time ≥ 4 h) or the nonfasting group (fasting time < 4 h). According to the gallbladder classification scheme, the gallbladders were classified into 4 types. The accuracy of diagnosing biliary atresia based on the gallbladder classification scheme was compared between the 2 groups. The gallbladders of 177 infants that were detectable by ultrasonography were used to compare the diagnostic performances between a junior radiologist and an experienced radiologist.Results-The accuracies in the diagnosis of biliary atresia with the gallbladder classification scheme were 86.3% (82 of 95 patients) for the fasting group and 93.5% (87 of 93 patients) for the nonfasting group (P = .100). The diagnostic accuracies of biliary atresia were 88.7% (157 of 177 patients) for the junior radiologist and 90.4% (160 of 177 patients) for the experienced radiologist (P = .250). The κ value for the agreement between the 2 radiologists was 0.859. Conclusions-The performance of gallbladder diagnoses was not influenced by the fasting time with the use of the gallbladder classification scheme. Additionally, the gallbladder classification scheme may help junior radiologists to more effectively identify biliary atresia and nonbiliary atresia.
