乳糜腹水是由于腹腔内淋巴管损伤和阻塞,导致淋巴管扩张和破裂,使淋巴液溢于淋巴管外,积贮于腹腔内之故。乳糜腹水要和假性乳糜腹水相区别,因为两者在外观上都呈乳白色。乳糜腹水中的细胞数不多,而甘油三酯含量很高,可达400～4000毫克％,高于血浆中的浓度。在试管内,如将乙醚和乳糜腹水混和,振荡后静置片刻,因乳糜溶于乙醚中,腹水会变得清澈;加入苏丹Ⅲ酒精溶液染色,则脂肪球呈红色。假性乳麋腹水多见于慢性腹膜感染,内含大量细胞。由于细胞的变性,故其腹水主要含磷脂、蛋白质及胆固醇,而甘油三酯的含量不高,加乙醚振荡后,并不使之清澈。乳糜腹水可分为急性和慢性两型。急性者常突然发生 Chylous ascites is due to intraperitoneal lymphatic damage and obstruction, resulting in lymphatic dilatation and rupture, so that lymph fluid overflow in the lymphatic vessels, accumulated in the abdominal cavity so it. Chylous ascites should be distinguished from pseudo-chylous ascites because both are milky in appearance. Chylous ascites in the small number of cells, and triglyceride content is high, up to 400 ~ 4000 mg%, higher than the plasma concentration. In test tubes, such as ether and chylomicrons ascites, shake for a while, because of chylolysis in ether, ascites will become clear; adding Sudan Ⅲ alcohol solution staining, the fat globules red. False milk elk ascites more common in chronic peritoneal infection, containing a large number of cells. Because of cell degeneration, so the ascites mainly contains phospholipids, protein and cholesterol, and triglyceride content is not high, add ether after the oscillation, it does not make it clear. Chylomic ascites can be divided into two types of acute and chronic. Acute often happen suddenly
