【摘要】:目的:探讨常规超声对原发性胆囊癌的诊断及鉴别诊断价值。 方法:对318例胆囊病变进行常规超声检查,观察超声征象特征,将诊断结果与病理进行比较。重点分析灰阶超声征象单项指标的诊断作用、鉴别诊断方法及误诊原因。 结果:(1)灰阶超声单项诊断指标包括:①病灶形态不规则或胆囊壁毛糙;②病灶宽基底或胆囊壁局限性增厚;③病变处囊壁连续性中断;④单发病灶;⑤病灶直径≥10mm或胆囊壁厚度3mm;⑥伴发胆囊结石。比较胆囊良恶性病变差异均有统计学意义(P0.05)。(2)与病理比较,常规超声诊断原发性胆囊癌的灵敏度、特异度、假阳性率、假阴性率、阳性预测值、阴性预测值分别为73.3%、97.2%、26.7%、2.8%、73.3%、97.2%。 结论:常规超声对原发性胆囊癌的诊断及鉴别诊断有重要价值。灰阶超声征象单项指标对胆囊良恶性病变有诊断指导意义。
[Abstract]:Objective: to evaluate the value of conventional ultrasound in the diagnosis and differential diagnosis of primary gallbladder carcinoma. Methods: 318 cases of cholecystic diseases were examined by conventional ultrasound, and the features of ultrasonic signs were observed. The diagnostic results were compared with pathology. The diagnostic function, differential diagnosis method and misdiagnosis reason of single index of gray-scale ultrasonic sign were analyzed. Results the single diagnostic index of gray-scale ultrasound included the irregular shape of the lesions in 1 / 1 or the width of the base of the lesions or the local thickening of the gallbladder wall (3) the continuity of the cystic wall in the lesions was interrupted and 4 single lesions were detected. (5) focal diameter 鈮,
