目的 :分析CT检查对诊断阻塞性黄疸平面和原因的价值。方法 :67例阻塞性黄疸病人中男 40例 ,女 2 7例 ,年龄 2 0～ 70岁 ,其中肿瘤 45例 ,炎症 8例 ,结石 14例。结果 :扩张的肝外胆管在腹部扫描时所见为低密度环影 ,阻塞平面按其解剖部位分四部分 :肝门段、胰上段、胰腺段及壶腹段 ,CT能准确地确定阻塞性黄疸平面 ,对梗阻原因的诊断准确率为 89 6%。结论 :在阻塞性黄疸的诊断中 ,CT检查可免去一些损伤性检查。
Objective: To analyze the value of CT examination in diagnosing obstructive jaundice and its causes. Methods: There were 40 males and 27 females in 67 cases with obstructive jaundice, ranging in age from 20 to 70 years old, including 45 cases of tumor, 8 cases of inflammation and 14 cases of stone. Results: The extrahepatic extrahepatic bile duct was seen as a low-density circumflex in abdomen scanning. The obstruction plane was divided into four parts according to its anatomical parts: the hepatic segment, the superior pancreatic segment, the pancreatic segment and the ampulla, and CT could accurately determine the obstruction Jaundice plane, the diagnosis of obstruction causes the accuracy rate of 89.6%. Conclusion: In the diagnosis of obstructive jaundice, CT examination may be exempt from some damage examination.
