为了提高实时超声显像胆囊癌的诊断准确率,作者回顾分析了29例超声假阴性,22例超声假阳性胆囊癌病例。在假阴性病例中,18例(62.1%)诊断为胆囊结石,6例(200.7%)误诊为急慢性胆囊炎,2例(6.9%)诊断为胆泥,2例(6.9%)诊断为息肉,1例(3.4%)诊断为肝脏肿瘤。在假阳性病例中,7例(31.8%)误诊为胆囊壁肿块但病检证实为息肉(4例)和胆泥(3例);8例(36.4%)误诊为胆囊壁不规则增厚,但组织学显示为急性(3例)和慢性(5例)胆囊炎。7例(31.89%)肝门显示有实质性肿块,超声提示为胆囊癌,其中2例为胆泥形成的肿物,5例为急性胆囊炎并积浓。
In order to improve the diagnostic accuracy of real-time ultrasound imaging gallbladder carcinoma, the author retrospectively analyzed 29 cases of ultrasound false-negative and 22 cases of ultrasound-positive gallbladder carcinoma. Among false-negative cases, gallstones were diagnosed in 18 cases (62.1%), 6 cases (200.7%) were misdiagnosed as acute and chronic cholecystitis, 2 cases (6.9%) were diagnosed as gallbladder, and 2 cases (6.9%) were diagnosed as polyps. One case (3.4%) was diagnosed as a liver tumor. Among the false positive cases, 7 cases (31.8%) were misdiagnosed as gallbladder wall masses, but the pathological examination confirmed polyps (4 cases) and bile mud (3 cases); 8 cases (36.4%) were misdiagnosed as irregular thickening of the gallbladder wall. However, histology showed acute (3 cases) and chronic (5 cases) cholecystitis. In 7 cases (31.89%), there was a solid mass in the hepatic hilum. Ultrasound showed gallbladder cancer, of which 2 were gallbladder-formed masses and 5 were acute cholecystitis and concentrated.
