Ultrasound diagnosis of biliary atresia

Objective：To analyze the ultrasound features of the gallbladder in infants with biliary atresia（BA） and explore the relationship between gallbladder shape and biliary atresia.Methods：The ultrasound features of gallbladder shape of 40 cases with BA were retrospectively analyzed and compared with those of non-BA proved by operation at the same period.Results：The gallbladder was identified in 38 cases（and not detectable in 2）.Its length was less than 1.5cm in 17 and the lumen was 1～3mm wide,17 Gallbladders had diameters ranging from 1.5cm to 4cm and inner diameters from 3mm to 5mm.Of these 17,11 had inflexible wall,5 had uneven wall,and 1 showed beaded appearance and had diverticulum.Furthermore,4 cases had diameters exceeding 4cm,inner diameters from 5mm to 10mm,and had irregular wavelike wall.In 10 cases small cyst was detected at hepatic hilus area,the diameter was from 1～2cm in 6 and from 2～4cm in 4.All the cysts did not connect with the right and left bile duct,one connected with GB duct,others were isolated cysts.The bile duct within the liver was not dilated in all cases.Conclution：Gallbladder shape and small cyst at porta hepatis area are of dependable foundation in the diagnosis of BA.
