Abstract:
Objective:To evaluate the value of ultrasonography in the differential diagnosis of cystic biliary atresia (CBA) and choledochal cyst (CC) in infants.Methods:CBA or CC children <3 months of age diagnosed by surgery in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from 2015 to 2023 were collected, and the differences in general conditions and ultrasound manifestations between CBA group and CC group were retrospectively analyzed.Results:Among the 55 children, 30 were in CBA group and 25 were in CC group. The mean length diameter and width diameter of cysts in the CBA group were about (1.45±1.05)cm and (1.04±0.73)cm, respectively, which were significantly smaller than those in the CC group (5.41±2.98)cm and (3.21±2.90)cm ( P<0.001). The incidence of fibrous plaque (50.0%, 15/30) and abnormal gallbladder morphology (73.3%, 22/30) in the CBA group was significantly higher than that in the CC group [4.0%(1/25) and 16.0%(4/25), respectively]. The incidence of intrahepatic biliary mud deposition (52.0%, 13/25) and intrahepatic biliary duct dilation (64.0%, 16/25) in the CC group was significantly higher than that in the CBA group [0, 3.3%(1/30), respectively]. Conclusions:There are some differences in ultrasonography between CBA and CC children. The length and width of cysts in children with CC are significantly larger than those in children with CBA, and biliary mud deposits or intrahepatic bile duct dilatation are seen in the cysts. The incidence of fibrous plaque and abnormal gallbladder morphology in CBA children is significantly higher than that in CC children.
