The gallbladders of 65 patients with ascites were examined on ultrasonograms. In 37 patients, the thickness of the gallbladder wall was less than or equal to 3 mm and was considered normal or "single." In 28 patients, the gallbladder wall thickness was greater than or equal to 4 mm, with a central echo-free zone giving the appearance of a double wall. Of the 37 patients with single-walled gallbladders, 35 (95%) had carcinomatous peritonitis. Of the 28 patients with double-walled gallbladders, 23 (82%) had benign disease, such as liver cirrhosis (n = 22) and nephrotic syndrome with hypoalbuminemia (n = 1). The results of this study indicate that sonography is useful in determining whether the cause of ascites is malignant or benign disease.
对65例腹水患者的胆囊进行了超声检查。37例患者胆囊壁厚度小于或等于3mm，被认为正常或为“单层”。28例患者胆囊壁厚度大于或等于4mm，中央有无回声区，呈现出双层壁的外观。在37例单层胆囊壁的患者中，35例（95%）患有癌性腹膜炎。在28例双层胆囊壁的患者中，23例（82%）患有良性疾病，如肝硬化（n = 22）和伴有低白蛋白血症的肾病综合征（n = 1）。本研究结果表明，超声检查有助于确定腹水的病因是恶性疾病还是良性疾病。
