摘要
目的:分析胃肠造影、B超、CT和内镜逆行胰胆管造影(ERCP)在恶性黄疸诊断和鉴别诊断中的作用。方法:对83例恶性黄疸包括胰腺癌、肝外胆管癌和壶腹癌分别进行胃肠造影、B超、CT和ERCP检查,分析四种影像学检查的诊断阳性率和正确率,不同恶性肿瘤的特异性检查方法。结果:B超为安全、简便的检查方法,可作为诊断的首选检查,诊断阳性率为9767%,诊断正确率为6069%,特别对壶腹癌诊断正确率达8182%,接近于CT和ERCP。ERCP对恶性黄疸检查阳性率为9848%,总的诊断正确率为8872%,且假阳性和假阴性均较低,特别对胆总管下段病变如壶腹癌、胰头癌等的定性明显优于CT和B超。CT的诊断阳性率为9259%,正确率为8616%,同时能显示出肿瘤及其周围组织情况。胃肠造影有较高的假阳性和假阴性率,对恶性黄疸检查敏感性较低。结论:B超和CT均为无创伤性检查,可作为恶性黄疸常规检查方法,并可了解肿瘤及其周围组织情况。ERCP可作为B超和CT的进一步检查方法。胃肠造影不能作为恶性黄疸诊断和鉴别诊断的必需检查。
Objective: To compare the value of image examination in the differential diagnosis of malignant
jaundice. Methods: 83 cases of malignant jaundice were examined by the barium meal
examination B-ultrasonographyCT and ERCP. Four kinds of image examination were analysed
in diagnosis and differential diagnosis of malignant jaundice. Results: B-ultrasonography acted
as a method of diagnosis for the first time because of safe and simplicity. Its positive rate was
97.67% and correct rate of diagnosis was 60.69%. Positive rate of endoscopic retrograde
cholangiopancreatography(ERCP) was 98.48% and correct rate was 88.72% in diagnosis of
malignant jaundice. Its false positive and negative rate were more lower and ERCP was
superior to B-ultrasonography and CT in diagnosis of diseases of lower common bile duct such
as papillary cancercarcinoma of the pancreas and etc. CT was a non-traumatic examination and
its positive rate was 92.59% and correct rate was 86.16%. The largest advantage of CT was able
to show candition of cancer and surrounding tissue at the same time. It was not essential that
barium meal examination act as a method of diagnosis of malignant jaundice because of its
false positive and negative rate was very high. Conclusion: B-ultrasonography and CT were
non-traumatic examination and may act as a routine method of differential diagnosis. They may
show condition of cancer and surrounding tissue. ERCP may act as a method of examination
after B-ultrasonography and CT.
