An analysis of 362 cases of obstructive jaundice

From October 1954 to December 1981,362 cases of obstructive jaundice verified by surgery or autopsy were seen in our hospital and the results of observation were reported in this article. The main causes of obstructive jaundice in this series were gallatones（225 cases,62.67%）and malignant tumors（129 cases,35.39%）.A complete history and physical examination usually provide the basis for a tentative diagnosis,while special tests and imaging procedures available in recent years are more helpful for the differential diagnosis.Although the ratio of serum bilirubin to SGPT,the ratio of serum bilirubin to AKP and the levels of Lp-X.GGT₁.,GGT₂ as well as cholic acid in the serum have a significant value in the differential diagnosis of jaundice,yet do not indicate the nature and site of the diseases clearly.On the other hand,imaging procedures, especially ultrasonography,CT,and cholangiography（PTC.ERCP）are now available for this goal. The reasonable evaluation procedure of obstructive jaundice was also discussed by the writers.
