Abstract: Clinical analysis was made in 33 cases of non-hepatic ascites admitted to the department of gastroenterology from December,1987 to May,1993. Of 33 cases(14 males and 19 females;age range 17 to 23,mean 49) ,18 cases(54.6%) were proved to be malignant ascites and 8 cases(24.2%) were due to tuberculosis. Malignant tumor and turberculosis are the most common causes of non-hepatic ascites.Besides routine test and pathologic test of ascites,endoscopy,CT,chest X-ray,ultrasonography and DSA are also helpful to establish the diagnosis;Ultrasonography is recommended as a convenient,nonexpensive and non-traumatic diagnostic aid.
