正常人体腹腔内有少量液体,一般不超过200毫升。如果因为某些原因引起腹腔内游离液体增多,称为腹水。当腹水超过1500毫升,作体检时才能被发现。腹水是临床常见的体征之一,病因复杂。发现腹水之后,还应进一步诊断是感染还是非感染性腹水,是肿瘤还是非肿瘤性腹水,以便指导治疗。为此,我们就腹水诊断问题进行讨论。 Normal human abdominal cavity with a small amount of liquid, usually not more than 200 ml. If for some reason caused by intra-abdominal fluid increases, called ascites. When the ascites more than 1500 ml for physical examination can be found. Ascites is one of the common clinical signs, the etiology is complicated. After the discovery of ascites, further diagnosis should be made whether the infection or non-infectious ascites, tumor or non-neoplastic ascites, in order to guide the treatment. For this reason, we discuss the diagnosis of ascites.
