Erste Ergebnisse der Implantation selbstexpandierender Nitinolstents in den Ösophagus bei maligner Dysphagie

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.

Ultraflex stents for the management of airway complications in lung transplant recipients

“…Problems associated with both silicone and metallic stents (Gianturco and Wallstent) include migration, mucus plugging and formation of granulation tissue 3–6 . In 1993, a new stent type, made of ‘nitinol’ was introduced to treat benign and malignant stenosis of the oesophagus 7,8 . This stent type has also been used in the management of biliary stenosis 9 .…”

“…Insertion of self-expanding stents is already an established procedure in the bile ducts, oesophagus, stomach, colon and rectum [1,2,3,4].…”
