Ultrasound is a sensible and specific method for the diagnosis, study of natural course and follow up of medical treatment of gallstones. Thus it is important to specify the concordance between echographic and pathological findings of the gallbladder. Ninety one patients were subjected to an ultrasound gallbladder examination immediately before elective surgery and the excised organ was pathologically examined right after the operation. The number and size of stones, the diameters and wall thickness of the gallbladder and the presence of polyps and septa were compared with both methods. The correlation was fair for the number or size of the stones considered separately; however the correct diagnosis of both parameters was obtained in only a third of the cases. Diameters of the gallbladder were underestimated by ultrasound; wall thickness measurement showed a very good correlation with both methods. No correlation was found for polyps or septa. Although ultrasound is excellent for the diagnosis of gallstones, its precision, is insufficient to determine the exact number and size of the stones.
超声是一种用于胆结石诊断、自然病程研究及治疗随访的合理且特异的方法。因此，明确胆囊超声检查结果与病理结果之间的一致性很重要。91例患者在择期手术前即刻接受了胆囊超声检查，术后立即对切除的器官进行了病理检查。用两种方法比较了结石的数量和大小、胆囊的直径和壁厚度以及息肉和隔膜的存在情况。单独考虑结石的数量或大小时，相关性尚可；然而，仅在三分之一的病例中同时正确诊断了这两个参数。超声低估了胆囊的直径；壁厚度测量显示两种方法的相关性非常好。未发现息肉或隔膜有相关性。虽然超声对胆结石的诊断很出色，但其精确度不足以确定结石的确切数量和大小。
