ResumenLa gammagrafía y la colangiorresonancia de hígado y vías biliares (CRMN) desplazaron la prueba de la sonda duodenal (PSD) en el estudio de ictericia colestásica por atresia de las vías biliares extrahepáticas (AVBE). Demostrar utilidad de la PSD asociada a ultrasonido de abdomen (USA), en el diagnóstico de AVBE. Cuatro casos con ictericia colestásica se sometieron a PSD y USA; uno de ellos, a CRMN. La PSD fue negativa para bilis en los 4; el USA no demostró vesícula, o la demostró pequeña o irregular, o detectó cordón fibroso; la CRMN mostró quiste de colédoco, pero no AVBE asociada; cirugía y patología documentaron AVBE en los 4. La PSD asociada a USA demuestra ausencia de bilis en el duodeno y anormalidad de la vesícula, respectivamente, lo que conduce a exploración quirúrgica en 24 a 48 h.AbstractLiver and biliary tree scintigraphy and magnetic resonance cholangiography (MRC) have taken the place of the duodenal tube test (DTT) in the study of cholestatic jaundice due to extrahepatic biliary atresia (EBA). The usefulness of DTT associated with abdominal ultrasound (AUS) in the diagnosis of EBA was demonstrated in 4 patients presenting with cholestatic jaundice that underwent DTT and AUS; one of them also had MRC. DTT was negative for bile in the 4 patients; AUS did not identify the gallbladder or showed it as small and irregular, or detected a fibrous cord; MRC identified a choledochal cyst but no associated EBA; surgery and pathology study documented EBA in all 4 patients. DTT associated with AUS demonstrated the absence of bile in the duodenum and gallbladder abnormality, respectively, leading to surgical exploration within 24 to 48hours.
