Evolution of therapeutic bronchoscopic methods in the last decade made possible to introduce new types of endobronchial prosthesis. We present our exerience with different types of stents in the last two years.
From January, 2001 to December, 2002 we inserted 161 stents in 133 patients. In most of the cases this was performed for palliation of different malignant tumors. 22 Ultraflex stents in 19 patients, 87 Dumon stents in 76 patients and 52 Y stents in 51 patients were inserted. Among the Y stents we used Freitag dynamic stent in 14 cases, while silicone Y stents were insereted in 38 cases. In 8 cases two or more stents were inserted in the same time.
Removal of the stents were necessary for tumor overgrowth in malignant lesions, or in benign cases. While removal of the silicon prosthesis were easy, and safe, the self expandable Ultraflex stents caused several complications.CONCLUSIONS: Our finding suggests that in cases of malignant processes all of the stent types can be useful, the choice is depending of the length and type of obstruction. In cases of benign lesions (postintubational stenosis, tracheomalatia, etc.) silicon stents are recommended with easier removal, and less complications.
Bronchoscopists performing stenting have to be familiar with different types of stents to be capable to choose among them.
