The thickening of the gallbladder wall in patients with ascites is commonly related to hypoalbuminemia and/or portal hypertension. To evaluate the pathogenetic role of these two factors, we correlated gallbladder wall thickness (GBWT) with the albuminemia and the serum-ascites albumin gradient (SAAG), an index of portal hypertension, in 47 patients with ascites caused by cirrhosis of the liver or abdominal malignancy. We found a thickened gallbladder wall in 30/47 patients. The correlation between GBWT and SAAG was 0.64 (n = 47 p less than 0.001). No correlation was found between GBWT and albuminemia (r = 0.04). We suggest that the sonographic finding of ascites and gallbladder wall thickening should be considered a valuable sign of transudative ascites and of portal hypertension whatever its cause.
腹水患者胆囊壁增厚通常与低白蛋白血症和/或门静脉高压有关。为评估这两个因素的致病作用，我们在47例由肝硬化或腹部恶性肿瘤引起腹水的患者中，将胆囊壁厚度（GBWT）与白蛋白血症以及门静脉高压指标血清-腹水白蛋白梯度（SAAG）进行了相关性分析。我们发现47例患者中有30例胆囊壁增厚。GBWT与SAAG之间的相关性为0.64（n = 47，p < 0.001）。未发现GBWT与白蛋白血症之间存在相关性（r = 0.04）。我们认为，无论病因如何，超声检查发现腹水和胆囊壁增厚应被视为漏出性腹水和门静脉高压的一个有价值的征象。
