Percutaneous transhepatic cholangiography with the Chiba needle

Percutaneous transhepatic cholangiography.

Chemical and histological studies are often unable to differentiate chronic extrahepatic obstructive jaundice (due to calculi, neoplasia, or stricture) from chronic intrahepatic obstructive jaundice (caused by primary biliary cirrhosis or by drugs, notably anabolic steroids and phenothiazine derivatives). Oral and intravenous cholangiography are also ineffective when the serum bilirubin is grea...

Percutaneous cholangiography with the Okuda needle.

Percutaneous cholangiography with the Okuda needle was performed in 42 consecutive patients with a clinical diagnosis of obstructive jaundice. Six had intrahepatic cholestasis. The technique demonstrated the biliary anatomy in 41 patients and the radiological diagnosis was confirmed by laparotomy, necropsy, or liver biopsy. There were no significant complications. Laparotomy, when indicated, wa...

New Methods for Diagnosis and Research PERCUTANEOUS TRANSHEPATIC CHOLANGIOGRAPHY

This is an evaluation of percutaneous transhepatic cholangiography, a technique of over eight years' standing, previously considered by many authorities as both unrewarding and dangerous. The value and risks of the procedure have been examined in 20 patients with obstructive jaundice of uncertain origin and in one further patient with a post-cholecystectomy syndrome. The presence and the nature...
