Clinical advance of bronchoscopic lung volume reduction in treating chronic obstructive pulmonary disease

Abstract

Objective Through summarizing the clinical advance of bronchoscopic lung volume reduction (BLVR)in treating chronic obstructive pulmonary disease (COPD),to provide more choices for the clinical treatment and research idea of COPD.Methods The related references in recent 20 years at home and abroad were collected,summarized and analyzed.Results BLVR was an minimally invasive technique with bronchoscopic to achieve lung volume reduction,which was no need thoracotomy according to the lung volume reduction surgery (LVRS) principle.The commonly used methods were bronchus blocking method and bronchial fenestration.Its purpose was to obtain LVRS benefits,and reduce the surgical trauma,risk and long-term rehabilitation process.Conclusions BLVR was a new treatment method with no need thoracotomy and small surgical trauma.In clinic,it reduced greatly the potential mortality and morbidity,and showed great clinical application prospect.But due to the lack of large-scale randomized controlled clinical trials,some methods were still in the animal experiment stage and lack of clinical research,so BLVR was still in its infancy.
