Abstract

SESSION TYPE: Therapeutic Bronchoscopy

PRESENTED ON: Sunday, October 21, 2012 at 01:15 PM - 02:45 PM

PURPOSE: The purpose of this study was to evaluate the feasibility, efficacy, and safety of a novel silicone stent designed for treating airway stenosis around the carina between the bronchus to the right upper lobe and bronchus intermedius (primary right carina).

METHODS: We recruited 16 patients for whom we suspected stenosis around the primary right carina. Of the 16 patients, 10 met inclusion criteria for inserting the study stent. All stenting procedures were performed with a flexible and rigid bronchoscope under general anesthesia.

RESULTS: The study stent could be placed on the primary right carina in all 10 patients. Five patients underwent stenting using only the study stent, and the other 5 underwent stenting with the study stent on the primary right carina and a silicone Y-stent on the main carina. The dyspnea index improved in 8 of 10 patients, including one mechanically-ventilated patient. Early complications occurred in 3 patients (temporary pneumonia in 2 and retention of secretions in 1), and a late complication occurred in 1 patient (granuloma formation).

CONCLUSIONS: Stent placement with our novel silicone stent designed to fit on the primary right carina is feasible, effective and acceptably safe.

CLINICAL IMPLICATIONS: Stenting with the novel silicone stent is promising for treating airway stenosis around the primary right carina.

The prototype bifurcated silicone stents (total 10 stents) were provided to the authors by Novatech, La Ciotat, France. This stent is now available in the market in Europe.
