[Sonograhic-radiologic evaluation of obstructive jaundice (author's transl)]

Retrospective evaluation of indication and technical procedure and its value in sonography of 110 patients with jaundice. A correct diagnosis (by ultrasound) of hepatogenic jaundice was made in 36/38 patients (94%) and of obstructive jaundice in 69/72 patients (96%). In additional 31/72 patients (43%) ultrasound gave important diagnostic clues by demonstrating dilated bile ducts as well as the location of obstruction. For verification and for the demonstration of morphologic changes, sonographically guided fine needle aspiration puncture, percutaneous transhepatic cholangiography with a fine puncture neede (Chiba-needle) and ERCP are indicated.
