Abstract:
Objective To observe the characteristics of infant biliary atresia(BA)missed diagnosis by ultrasound.Methods Data of 72 BA infants missed by ultrasound(false-negative,group A),72 BA infants accurately diagnosed by ultrasound(true-positive,group B)and 72 non BA infants(controls,group C)were retrospectively analyzed.Clinical and ultrasonic features were compared between each 2 groups.Logistic regression analysis was performed to screen the impact factors for diagnosing and missed-diagnosing of BA.Results There were significant differences of total bilirubin,direct bilirubin,gamma glutamyl transpeptidase(GGT)and glutamic-oxaloacetic transaminase(GOT)between group A and C,also of total bilirubin,direct bilirubin and GGT between group B and C(all P＜0.05).Significant differences of the incidences of small gallbladder,gallbladder wall rigidity,poor gallbladder contraction function and fibrous plaques in the hepatic hilum were found between group A and B,of undetected or cystic changes in the gallbladder,gallbladder wall rigidity,poor gallbladder contraction function,fibrous plaques in the hepatic hilum and hepatic hilum cysts were noticed between group A and C(all P＜0.05),as well as of undetected or cystic changes in the gallbladder,small gallbladder,gallbladder wall rigidity,gallbladder wall thickening,poor gallbladder contraction function and fibrous plaques in the hepatic hilum were detected between group B and C(all P＜0.05).There were significant differences of display rate of common bile duct between each 2 groups(all P＜0.05).The lower incidence of fibrous plaques in the hepatic hilum and poor gallbladder contraction function were an impact factors for missed diagnosis of BA(both P＜0.05),while higher GGT,higher incidence of fibrous plaques in the hepatic hilum and poor gallbladder contraction function were all impact factors for diagnosis of BA in group A(all P＜0.05).Conclusion Infant BA missed diagnosis by ultrasound had lower incidence of fibrous plaques in the hepatic hilum and poor gallbladder contractile function.Combining with clinical data was helpful for reducing ultrasonic missed diagnosis of BA in infants.
