９００余例经皮肝穿刺胆道造影（ｐｅｒｃｕｔａｎｅｏｕｓｔｒａｎｓｈｅｐａｔｉｃｃｈｏｌａｎｇｉｏｇｒａｐｈｙ，ＰＴＣ）检查的患者中，同时做过Ｂ型超声（Ｂｕｌｔｒａｓｏｕｎｄ，ＢＵＳ）检查并经手术证实为胆道肿瘤的有５０例。该组病例中胰头癌２４例，壶腹癌９例，胆管癌１３例，胆囊癌１例，肝门肿瘤３例，三种检查方法对胆道肿瘤诊断的符合率分别为：ＰＴＣ８２％，ＢＵＳ４４％，ＰＴＣ＋ＢＵＳ８８％。ＰＴＣ对确定胆道肿瘤的存在和病变部位极有价值，其诊断符合率较ＢＵＳ等影象诊断方法为高，应做为胆道肿瘤的主要诊断手段之一。ＢＵＳ虽然诊断符合率较低，但其具有经济、无痛苦、便于重复检查等优点，应做为该类疾病的首选检查方法，诊断不明时再做ＰＴＣ等检查。
Among the more than 900 patients who underwent percutaneous transhepatic cholangiography (PTC), there were 50 Bultrasound (BUS) examinations and 50 biliary tract tumors confirmed by surgery. In this group of patients, there were 24 cases of pancreatic head cancer, 9 cases of ampullary carcinoma, 13 cases of cholangiocarcinoma, 1 case of gallbladder carcinoma, and 3 cases of hepatic portal neoplasms. The coincidence rates of the three examination methods for diagnosis of biliary tumor were: PTC82%, BUS44 %, PTC+BUS88%. PTC is extremely valuable in determining the presence of biliary tract tumors and lesions. The diagnostic compliance rate is higher than BUS and other diagnostic imaging methods and should be used as one of the main diagnostic tools for biliary tract tumors. Although the diagnosis rate of BUS is relatively low, it has the advantages of economy, painlessness, convenience for repeated inspections, etc. It should be used as the preferred inspection method for such diseases, and PTC and other tests should be performed when the diagnosis is not clear.
