摘要
目的 :探讨ERCP后利用留置管进行螺旋CT仿真内窥镜 (CTVE)检查胆系疾病的诊断价值。材料和方法 :对 2 6例行ERCP术后的患者行螺旋CT扫描和CTVE重建 ,分析CTVE图像显示病变的能力。结果 :CTVE图像显示 ,胆管、胆囊未见明显异常 5例 ,表现为胆管内径匀称 ,壁光整 ;胆系结石 14例 ,见胆管或胆囊内光整的隆起性改变 ,临近管壁光整 ;胆系癌肿 5例 ,表现为腔内隆起性改变 ,表面不光整 ,周围管壁凹凸不平 ;胆总管炎性狭窄 2例 ,表现为胆总管腔渐进性狭窄。结论 :ERCP后CTVE较为满意地显示了胆系疾病腔内改变的细节 ,可获得类似于内窥镜效果的图像 ,对临床诊断提供了有价值的信息。
Purpose: To evaluate the usefulness of CT virtual endoscopy (CTVE) using ERCP draining duct in the patients with biliary disease.Materials and Methods: Spiral CT scan and CTVE reconstruction were performed in 26 patients after injection of 30% Angiographin through ERCP draining duct. The CTVE images were analysed and the ability of revealing lesions was evaluated.Results: CTVE images yielded fruitly. Five of the 26 patients exhibited no significant abnormal, the cavity size of biliary cyst was regular and the wall of biliary duct was smooth; In 14 cases with bile duct stone, there were regular and smooth prominences with normal biliary wall. There were 5 malignant tumors with stenoses in biliary cavity. The surface of the lesions and surrounding biliary wall were irregular. In 2 cases with inflamative narrow, a gradual narrowing of the bile duct was observed.Conclusion: CTVE is a valuable and feasible technique for satisfactorily revealing detail changes in biliary cavity. It can show and obtain images similar as that of endofibroscopy. CTVE can provide valuable information in the clinical diagnosis for biliary diseases.
