摘要
目的探讨CT对梗阻性黄疸诊断价值。方法对32例经超声诊断不满意的梗阻性黄疸患者行CT平扫,增强扫描和梗阻局部薄层扫描。结果32例梗阻性黄疸病例中,良性梗阻性黄疸23例,误诊2例(胆总管等密度结石及慢性炎性狭窄各1例);恶性梗阻性黄疸9例中,误诊1例(胆总管癌)。结论CT对梗阻性黄疸有极高的定位与定性诊断价值。通过对梗阻平面的判定及梗阻端的征象分析,正确解释梗阻原因,可提高术前诊断正确率。
Objective To assess the usefulness of computed tomography (CT)in the diagnosis of obstructive jaundice.Methods Thirty-two patients with obstructive jaundice that is unsatisfied on ultrasonography underwent CT plain scan and enhancement scan as well as thin slice scan within the obstructive locations.Results Among 23 patients with benign lesions,CT correctly diagnosed 21 cases and misdiagnosed 2 cases (each of common bile duct's isodense calculi and chronique inflammatory stenosis had 1 case),while among 9 patients with malignant obstructions,CT correctly diagnosed 8 cases and misdiagnosed 1 case (common bile duct's carcinoma). Total qualitative accuracy of preoperative CT diagnosis in the study was 90.6%(29/32).Conclusion CT has high accuracy in the locative and qualitative diagnosis of obstructive jaundice.The identification of obstructive plane,careful analysis of obstructive end signs,and correct explain of obstructive causes are critical steps to improve the accuracy of preoperative diagnosis.
