• W2045467996 abstract "Introduction: The purpose of this study was to assess patency rates, need for subsequent interventions, and survival after endoscopic placement of a new biliary stent made of Nitinol (Diamond stent®, Boston Scientific) versus standard plastic stent (PS,Wilson Cook) in patients with malignant biliary obstruction. Methods: Since 3/98, such patients were randomized to placement of PS (with side holes; at least 10 fr) or the new metal stent (MS). Follow-up was by calls to the referring MD and record review with regard to stent patency (recurrent cholestasis, cholangitis) and survival. ERCP's were done by 2 experienced endoscopists. Results: Data are available for 33 pts,(43-93y; mean 75.2 y; 30 pancreatobiliary tumors, 3 with metastases of other tumors). Stenting was successful on 1st attempt in 30, on 2nd attempt in 3 pts (1 had PTCD). Initial Bilirubin was 1.2-26.9 mg/dl (mean 10.6).In 2 pts no Bilirubin decrease occurred after stenting, these pts were not analysed further. 3 complications occurred: septicemia, arm fracture (after positioning), and slight hemoglobin decrease in 1 patient each. Table: STENT PERFORMANCE Conclusion: Stent occlusion occurred more often with use of a plastic stent, necessitating stent changes in these patients. Patency rate of the new Nitinol stent was excellent. Survival did not differ between the groups. A cost and quality of life analysis will follow.
