Percutaneous transhepatic biliary drainage was performed in 8 patients with obstructive jaundice using combined real-time ultrasound and fluoroscopic guidance. Segmental (focal) biliary obstruction was present in 6 of 8 cases due to metastatic tumour obstruction (3), cholangiocarcinoma (1), biliary stricture (1), and retained stones (1). Two patients had distal obstruction secondary to pancreatic carcinoma. In addition to biliary drainage, selective cannulation was used in conjunction with balloon dilatation of a biliary stricture in one patient and for successful dissolution of retained biliary stones with methyl tert-butyl ether infusion in another patient. In all 8 cases, ultrasound was successfully used for initial puncture of the biliary system, requiring only one needle pass. Fluoroscopy was used for catheter placement and there were no complications related to initial catheter positioning. Combined use of ultrasound and fluoroscopy enhanced the advantages of each modality to allow precise needle placement into focally dilated biliary ducts for transhepatic cholangiogram, biliary drainage and other invasive biliary procedures.
