简要总结
Rationale: The bronchoscopic lung volume reduction treatment using vapor was found to be effective and the treatment has an acceptable safety profile. The results of this trial has led to the inclusion of this treatment in the COPD GOLD guidelines in 2019. In the Netherlands the treatment has not been performed so far but the treatment device has been made available to the UMCG hospital to perform emphysema treatments. Some of the patients refered to the UMCG could benefit from the Vapor treatment and therefore with this treatment we will be able to treat patients who have no other treatment options left.
Objective: The overall aim of this study is to gain experience with the Thermal Vapor treatment by investigating the safety and efficacy of the treatment.
Primary Objective:
The primary objective is to investigate the change in Lung function (measured by Forced Expiratory Volume in 1 second (FEV1)) between baseline and 6 months after the Thermal Vapor treatment.
Study designThis study will be a prospective observational, single center study. All patients that undergo the bronchoscopic lung volume reduction treatment using thermal Vapor will be asked if their data can be captured in the database.
Study population: Patients with severe COPD who undergo the Thermal Vapor treatment.
详细描述
Rationale: The STEP-UP trial investigated the bronchoscopic lung volume reduction treatment using vapor and showed that the treatment group significantly improved after 6 months compared to the control group in Lung function and quality of life. The authors also concluded that the treatment has an acceptable safety profile. The results of this trial has led to the inclusion of this treatment in the COPD GOLD guidelines in 2019. In the Netherlands the treatment has not been performed so far but the treatment device has been made available to the UMCG hospital to perform emphysema treatments. Yearly, approximately 600 severe emphysema patients are refered to the UMCG for a bronchoscopic treatment but only approximately 10% is suitable for a treatment with endobronchial valves or coils. Some of the other patients could benefit from the Vapor treatment and therefore with this treatment we will be able to treat patients who have no other treatment options left.
Objective: The overall aim of this study is to gain experience with the Thermal Vapor treatment by investigating the safety and efficacy of the treatment.
Primary Objective:
The primary objective is to investigate the change in Lung function (measured by Forced Expiratory Volume in 1 second (FEV1)) between baseline and 6 months after the Thermal Vapor treatment.
