“…22 A survey of the American Academy of Pediatric Surgery Section found that 13% of patients with cystic dilatation of the CBD had extrahepatic atresia. 23 In this study, 19 of 43 (44%) cases of infantile biliary tract dilatation had an association with BA. In the same period, we had 187 cases of BA cases, 10.6% with BDBA (19 of 187).…”

“…25 In the literature, the most common type of BDBA reported is type I cyst, which has been described as a correctable type of BA in the past. [22][23][24][25][26] However, some other types of BDBA have been reported. Bancroft and coworkers reported four type I cysts and one choledochal cyst contiguous with the cystic duct.…”

“…Bancroft and coworkers reported four type I cysts and one choledochal cyst contiguous with the cystic duct. 23 Redkar and colleagues reported a case of type III BA with a segmental cystic dilatation of the CBD. 26 In our study, in addition to 17 cases of type I cyst cases, we had 2 cases of type III BA with biliary tract dilatation, including 1 intrahepatic biliary duct dilatation and 1 cystic dilatation of the cystic duct.…”

We evaluated sonographically 162 children who met the criteria for biliary tract dilatation in the past 18 years. Of these, 131 patients were diagnosed as having anomalous dilatations of the biliary tree (including 112 with choledochal cysts and 19 with biliary duct dilatation and biliary atresia). Biliary tract dilatations in the other 31 patients were due to secondary causes or normal variants. All cases of intrahepatic biliary tree dilatation and those with both intra‐ and extrabiliary duct dilatations were anomalous. In 117 cases of extrahepatic biliary tract dilatation only, the mean diameter was widest in cases of choledochal cyst (21.4 +/‐ 12.1 mm, compared with cases of biliary tract dilatation with biliary atresia (10 +/‐ 2.4 mm), secondary biliary duct dilatation (8.5 +/‐ 1.5 mm), and normal variants (4.4 +/‐ 1.2 mm) (P < 0.001). Of the 43 infants with biliary tree dilatation, 24 (56%) had choledochal cysts and 19 (44%) had biliary tract dilatation associated with biliary atresia. Excluding cases associated with biliary atresia, the accuracy of diagnosing choledochal cysts in extrahepatic biliary tract dilatation was 71% and 97% using cutoffs of 7 mm and 10 mm as the minimum diameter, respectively.

“…Both choledochal cyst and congenital biliary atresia (type I cyst) may share the same ultrasonographic pattern. Pa tients with choledochal cyst rarely manifest jaundice im mediately after birth, and most of them can be followed for a certain period before surgical intervention is decided [1][2][3][4][5][6][7], On the other hand, in congenital biliary atresia, jaundice is present at birth in some cases, and the progno sis is greatly dependent on early surgical intervention before 10-12 weeks of age [2]. Hence early diagnosis is very important.…”

Is It Possible to Differentiate between Choledochal Cyst and Congenital Biliary Atresia (Type I Cyst) by Antenatal Ultrasonography?

Both choledochal cyst and congenital biliary atresia (type I cyst) may share the same ultrasonographic pattern. We report 2 cases which were shown to have cystic structures on the upper abdomen by antenatal ultrasonography. The size of the choledochal cyst found at 24 weeks’ gestation increased steadily as gestational age advanced. But the size of the cyst in congenital biliary atresia found at 29 weeks’ gestation remained unchanged throughout the remaining pregnancy. Cyst enlargement, therefore, may suggest the possibility of a choledochal cyst.

Early Prenatal Diagnosis of Choledochal Cyst

Unrecognized biliary tract obstruction due to choledochal cysts or biliary atresia can result in significant morbidity and mortality. Diagnosis in utero of choledochal cyst allows prompt postnatal diagnostic evaluation and appropriate surgical therapy to be instituted early in life. This may minimize the potential complications of cholangitis, cirrhosis, and liver failure in infants with choledochal cysts.
