对我院消化科１９８７年１２月～１９９３年５月收治的３３例非肝性腹水进行临床分析。３３例患者中，男性１４例，女性１９例。年龄１７～７３岁，平均年龄４９岁。恶性腹水１８例，占５４．６％（１８／３３）。结果显示非肝性腹水的最常见病因是恶性肿瘤和结核。除腹水常规和腹水病理检查外，必要的辅助检查，如胃肠镜、胸片、Ｂ超、ＣＴ和腹腔选择性血管造影对腹水的病因诊断很有价值。尤其是Ｂ超检查简便、经济、无创伤，更易被患者接受。 Clinical analysis of 33 cases of non-hepatic ascites admitted to Department of Gastroenterology from December 1987 to May 1993 in our hospital. Among the 33 patients, 14 were males and 19 were females. Age 17 ~ 73 years old, average age 49 years old. Malignant ascites in 18 cases, accounting for 54.6% (18/33). The results showed that the most common causes of non-hepatic ascites were malignancies and tuberculosis. In addition to ascites routine and ascites pathological examination, the necessary auxiliary examination, such as gastrointestinal endoscopy, chest radiograph, B ultrasound, CT and peritoneal selective angiography on the etiological diagnosis of ascites is valuable. In particular, B-ultrasound is simple, economical, non-invasive, and more acceptable to patients.
