Distinction between obstructive and non-obstructive jaundice by sonography.

The grey-scale ultrasound, as a non-invasive imaging device, has been applied in differentiating obstructive and non-obstructive causes in a group consisting of 115 random patients suffering from jaundice. The present communication illustrates the echographic evaluation and the final diagnoses and also reports the rate of accuracy, which is 96.6% in this study. It can be concluded that echography is an accurate method with no contra-indications for the evaluation of jaundice and should allow earlier surgery when indicated.
