PURPOSE: There are only few reports on fully covered self expandable metal stents (SEMS), and none on the new Leufen aerstant (Bess AG, Germany, Europe). Our objective is to report and analyze our experience with Leufen aerstet in the management of malignant tracheobronchial disorders.

METHODS: Retrospective review was done of medical records of patients who underwent fully covered SEMS, between October 2012 and October 2014.

RESULTS: 22 stents were placed in 19 patients, mean age 62 years old (SD 4), 84% males, with lung cancer (n=8), endobronchial metastasis (n=6) and esophageal cancer (n=5). The median follow-up were 44 days (range 21-318), with a median survival of 72 days (range 3-374). SEMS were inserted through a rigid bronchoscope under fluoro and endoscopic control in the main bronchi (n=13), trachea (n=8), tracheobronchial (n=1) and tracheobronchial with a telescoped bronchial (n=1). In 2 cases (9%) reimplant was needed, and the same stents were reloaded during the procedure. There were no migration, no metal fracture and no folding. Mucostasis was observed in 86% of the cases without mucous plug, mild granulation tissue formation in 31,7%, silicone coating detachment in 2 patients (9%) and polurethane coating perforated in 1 (4%). In 3 cases, stents were easily removed through rigid bronchoscope without complications.

CONCLUSIONS: The metal mesh from the Leufen SEMS present an outstanding performance, but some concerns arise from its coating after observing high mucostasis (86%) and detachment (9%).

CLINICAL IMPLICATIONS: Fully covered Leufen SEMS are safe, easy to implant, replace and remove in malignant tracheobronchial disorders.
