Abstract:
Objective To evaluate the feasilibility of ultrasonic cholangiography(USC)with contrast agent SonoVue in evaluating the obstructive bile duct diseases.Methods Twenty patients with obstructive jaundice(choledocholithiasis in 4,post-operative biliary strictures in 2 and malignant tumors in 14)underwent uhrasound-guided percutaneous transhepatic cholangiodrainge drainage(PTCD).Afterward,USC with contrast agent SonoVue administrated from the PTCD tube and percutaneous transhepatic cholangiography(PTC)were carried out in each patient.By using the surgical or PTC findings as reference standard,accuracy of USC in determining the obstructive level and cause of bstructive was evaluated.Results ①The visualization of contrast agent SonoVue was successfully obtained in all 20 patients,three order of bile duct was visualized in 19 patients.The visualization of the ultrasound contrast agent persisted more than 6 min.There was no side effect occurred during the procedure and no uncomfortable complaint after the procedure.②USC determined correctly in 18 cases.Compared with surgical or PTC findings,the accuracy of USC in determining obstructive levels was 90.0%(18/20),and the accuracy in determining the obstructive cause was 85.0%(17/20).Conclusions As a new and safe technique for cholangiography,USC is comparable to PTC in displaying the intrahepatic bite duct and determining the obstructive levels in patients with obstructive jaundice.
