  • Title: [Endoscopic implantation of balloon expandable endoprostheses (Strecker stents) in extrahepatic bile duct stenoses].
    Author: Nattermann C, Goldschmidt AJ, Dancygier H.
    Journal: Med Klin (Munich); 1992 Jul 15; 87(7):364-8. PubMed ID: 1508116.
    Abstract:
    22 balloon expandable wire Strecker-stents were implanted endoscopically in 20 patients (eleven women, nine men, mean age 68.3 [44 to 86] years) with malignant (n = 19) and benign (n = 1) bile duct obstruction. In all cases an effective biliary drainage was obtained. To achieve complete drainage repeated balloon dilatation of the inserted stent was often performed. In two cases stent dislocation occurred immediately after implantation. Additional complications were not observed during the first 30 days. During the observation period of maximally 15 months one patient developed an incomplete occlusion of the stent due to tumor compression that could be reversed endoscopically. In a further patient biliary stones caused relapse of cholestatic jaundice. Four patients died from their malignant disease without evidence of stent occlusion. 15 patients continue to live without renewed jaundice. With the mean observation period of 5.5 months (median five months) this corresponds to a patency rate of 95%. The estimated survival rate according to Kaplan-Meier was 87.7% and the estimated mean survival time 11.7 months. These results demonstrate that in patients with extrahepatic bile duct obstruction an effective biliary drainage can be achieved with balloon expandable wire stents. They represent a further progress in the palliative treatment of patients with extrahepatic obstructive jaundice.
