  • Title: [The initial results of the implantation of self-expanding nitinol stents into the esophagus in malignant dysphagia].
    Author: Wagner HJ, Schwerk WB, Stinner B, Kasper M, Klose KJ.
    Journal: Rofo; 1993 Nov; 159(5):450-5. PubMed ID: 8219139.
    Abstract:
    Nine patients (mean age 64, range 51-83 years), with dysphagia due to incurable malignant obstruction of the esophagus were treated by the introduction of 10 self-expanding metal endoprostheses (Nitinol stents). All cases were technically and functionally successful. In one patient the stent did not expand completely; it had to be removed and a second introduced. There were no other complications from the stent implantation. During the period of observation of 136 +/- 86 days one stent (11%) was reobstructed by tumor growing into the stent. Two patients died after 60 and 119 days, both with open stents. Early experience with the Nitinol stent indicates that good palliation of malignant dysphagia can be achieved with a much lower complication rate than results from tube implantation. The design and application system of the stent is capable of further improvement.
