Endoscopic Treatment

Condition(s) studied

Investigational drug(s) / intervention(s)

Informed consent: During the pre-inclusion/inclusion visit, the investigator informs the participant and answers all questions regarding the purpose, nature of the constraints, foreseeable risks and the expected benefits of the clinical investigation. The investigating physician then provides the participant with a copy of the information note and informed consent form. After this information session, the participant is granted a reflection period. If the participant agrees to participate

Eligibility criteria check: The investigator also specifies the participant's rights in the context of research and checks the eligibility criteria.

Randomisation: When an investigator wishes to perform the randomisation after checking the eligibility criteria and consent of the participant, he/she will connect to the dedicated Clinsight Website.

Dyspnea-12 questionnaire: The DYSPNEA-12 questionnaire helps to understand how shortness of breath impacts a patient's life. This questionnaire contains 12 questions that assess the physical and emotional aspects of dyspnea in daily life by checking one of the following boxes: not at all, slightly, moderately, severely

VQ11 questionnaire: The VQ11 questionnaire is a quality of life questionnaire. It contains 11 statements that express feelings about the consequences of a respiratory illness. For each statement, the patient must check the intensity that corresponds to their experience from among: not at all, a little, moderately, a lot, and extremely.

EQ-5D-5L questionnaire: This questionnaire assesses the patient's mobility, autonomy, activities, pain, and anxiety using 5 items. For each item, the patient must select the situation that best describes them from among 5 options: no problem, mild problems, moderate problems, severe problems, or unable to function.

Spirometry: non-invasive measurement of ventilatory function, including peak expiratory flow and forced expiratory volume in 1 second (FEV1)

Chest CT scan: High resolution chest CT scan without injection of contrast medium. The scanner required for the manufacture of the prosthesis must be a high-resolution CT scanner, the recommendations for which are specified in the order file for a 3D stent

Commercially Stent Implantation: During the commercially stent implantation, a video of the procedure will be recorded and all the pseudonymized videos of each center will be centralized and stored in the pulmonology department of Pr Nicolas Guibert of CHU of Toulouse.

Experimental Stent Implantation: During the experimental stent implantation, a video of the procedure will be recorded and all the pseudonymized videos of each center will be centralized and stored in the pulmonology department of Pr Nicolas Guibert of CHU of Toulouse.

Study summary

The placement of an endoprosthesis in the airways leads to rapid and dramatic clinical improvement in the majority of cases of central airway obstruction. However, the limited diversity of device shapes available on the market is a major limitation, as these devices are poorly adapted, or not adapted at all, to the patient's anatomy. The main consequences of this lack of congruity are stent migration and granulomatous inflammatory reactions. The investigators hypothesized that personalized endoprostheses could significantly reduce the complication rate and improve tolerability. In this randomized controlled trial, the investigators propose to evaluate whether personalized endoprostheses allow for better management of non-malignant central airway stenoses by comparing this new approach to standard care.
