目的通过多层螺旋CT进行(Percutaneous transhepatic cholangial drainage,PTCD)的术后评价。方法对35例PTCD术后患者通过留置的引流管注入造影剂,观察引流管走形,周围软组织病变情况,准确评估PTCD术。结果 1例出现引流管头部卷折,其余均可清晰显示引流管走行及胆管周边形态及十二指肠乳头部。结论多层螺旋CT对PTCD术后评价及对原发病灶诊断及胆道侵及情况能作出更为准确的判断,减少PTCD并发症的发生。
Objective To evaluate the postoperative evaluation of percutaneous transhepatic cholangial drainage (PTCD). Methods Thirty-five patients with PTCD were injected with contrast agent through the indwelling drainage tube to observe the shape of the drainage tube and the surrounding soft tissue lesions and to evaluate PTCD accurately. Results 1 case of drainage tube head roll, the rest can clearly show the drainage tube and bile duct circumference and duodenal papilla shape. Conclusions Multi-slice spiral CT can make a more accurate judgment of the postoperative PTCD evaluation and diagnosis of primary lesions and biliary tract invasion, and reduce the occurrence of PTCD complications.
