The importance of ultrasonography in the evaluation of jaundice is stressed with an analysis of 47 cases ofjaundice. 31 cases proved to be obstructive and 16 non-obstructive jaundice. Obstructive jaundice could bedifferentiated from non-obstructive jaundice in all but 2 cases,(96%). The site of obstruction in 31 cases ofobstructive jaundice could be predicted correctly in 23 cases of 31, (90%), and cause of obstruction with anaccuracy of 35% as well. One can certainly recommend ultrasonography as an initial procedure of choice in jaundicepatients.
