For tumorstenosis and fistulas near the bifurcation Y-stents are needed. The eco-YStent ® is the first selfexpanding Y-Stent made of metal. In the last 3 years till May 2009 we implanted these stents in 37 patients in our clinic, which is approximately 40% of all the stents, implanted in this period of time. Indications were malignant tumors in 34 cases, including 17 lung cancers and 14 esophageal cancers. In 3 cases the indication was a benign lesion. 12 patients had esophago-respiratory fistulas. The implantation was done in general anaesthesia with a rigid bronchoscope under X-ray control and was easily done in most patients. When needed, the stent could be combined with another selfexpandible stent. Fistula symptoms were resolved immediately. In some cases the obstruction of the stent was a problem. In those patients numerous bronchoscopies for cleaning the stent had to be done and in 3 cases the stent had to be removed, which was done without difficulty. The stent is very valuable and especially useful for the stenting very far progressed lesions.
