Abstract: Objective: To evaluate the clinical effects of percutaneous transhepatic cholangial drainage( PTCD) combined with biliary metal stent placement in the treatment of elderly patients with malignant obstructive jaundice. Methods: Fourty-six patients over 70 years old with malignant obstructive jaundice were treatedwith PTCD under the guidance of ultrasound. The biliary metal stent was implanted into PTCD sinus under digital subtraction arteriography in a week after operation,external drainage converted to internal drainage by the way. Results: The serum total bilirubin in 46 cases post-PTCD decreased significantly( P 0. 01),and liver function was improved( P 0. 01). The mean survival priod was( 10. 53 2. 35) months after operation. Conclusions: PTCD combined with biliary metal stent placement for treating elderly patients with malignant obstructive jaundice is an effective way. The way can improve quality of life,and is implicity,safety,good efficacy and minimal trauma,which can be the preferred approach to treat elderly patients with malignant obstructive jaundice.
