Ultrasonography in the diagnosis of obstructive jaundice

Ultrasonography was employed in the diagnosis of obstructive jaundice. In a group of 38 patients who were studied, Ultrasonography was found to be reliable in confirming the diagnosis. In majority of the cases it was also found to be reliable in revealing the cause of obstruction. Nineteen of these patients were examined by percutaneous transhepatic cholangiography (PTC) and there were 100 per cent correlation with Ultrasonography. Twelve of these patients underwent operation and the findings were in good agreement with those of Ultrasonography.
