Imaging findings in patients with biliary atresia in Carlos Andrade Marín Specialties Hospital, in the period between Jan 2016-Mar 2017

Abstract

Introduction. This is a review of clinical and radiological findings of biliary atresia, an

anomaly of biliary tree development that carries a high risk of mortality due to complications unless they are corrected in a short time. Materials and methods. We reviewed a series of seven cases reported at Carlos Andrade Marín Specialties Hospital, from January 2016 to March 2017. Six women and one male were followed. All of them showed clinical signs such as long term jaundice, cholestasis, as well as, imaging findings and liver biopsies, suggesting biliary tract atresia. Results. All patients presented jaundice and choluria, in laboratory tests a cholestasic pattern in all of them, in the imaging studies the predominant finding in suspicion of biliary atresia was the absence of gallbladder and the triangular cord sign in only three patients, in the liver biopsy all of them showed some degree of liver fibrosis. Discussion. Bile duct atresia is a complex and serious disease. In our case serie we confirmed the utility of ultrasound as diagnosis method in biliary duct atresia, is more available than magnetic resonance which is more expensive and less available in different centers. Conclusion. Abdominal ultrasound is an extremely valuable tool in clinical suspicion of biliary atresia, a timely diagnosis must be made to improve patient´s prognosis.
