The preliminary study on patients with severe emphysema, endoscope light source, endoscope high color light source can be used for minimally invasive and peep mirror in the lungs of coil implantation improved exercise capacity within 6 months, although high short-term costs, according to a study in the Journal of the American Medical Association.

An important part of emphysema, chronic obstructive pulmonary disease, lung tissue is composed of elastic and hyperinflation, dyspnea (shortness of breath), limited movement, and impaired quality of life. The treatment of severe emphysema is a challenge, because the existing treatments have limited efficacy. Lung volume reduction surgery, which has demonstrated clinical benefit with major diseases and death. Using an endoscope light source, endoscope high color light source, the Ni Ti lung volume reduction (metal alloy coil is bronchoscopic interventional (using a thin, flexible endoscope) - induced weight reduction and recovery of lung recoil, according to background information in the article.
He deslee, MD, PhD, University Hospital of Reims, France and colleagues randomly assigned severe emphysema patients with conventional treatment (n = 50; no inhaled glucocorticoid, oxygen accept rehabilitation therapy and bronchodilator) or bilateral coil treatment (n = 50; accepted routine nursing plus additional treatment, which about 10 per coil valve implantation of two sides of the leaf 2 program). The use of endoscope light source, endoscope high color light source of the 10 university hospitals in France for the.
The main research results, at least 54 meters (59 yards) improvement in the 6 months after 6min walk test were observed in 18 cases (thirty-six percent) of the coil group and 9 patients (eighteen percent) in the conventional therapy group. endoscope light source, endoscope high color light source coil treatment and pulmonary hyperinflation decreased significantly, continuously improve the quality of life. The average total cost difference of 1 years for each patient group for $47908.
The author writes, if it is assumed that the quality adjusted life years (QALY) gain can be maintained for at least 3 years, two groups of the same follow-up costs, the incremental cost-effectiveness ratio of approximately $270000 per QALY, close to the incremental cost-effectiveness ratio reported lung volume reduction surgery in the United States. " The benefit cost ratio in 1 years and 3 years, the model will not be considered effective, sufficient to ensure that the technology used in most countries. The implementation of this technique in a large population of emphysema may need this additional data for each patient, the cost is high, in the short term effect and uncertainty of the total expenditure on health care. "Further investigation is needed to assess the impact of long-term cost effectiveness."
Editorial: bronchoscopic lung volume reduction of COPD
"Further improvements in the clinical and X-ray features of clinicians can expect to be able to provide greater clinical medicine based precision matching a given technology characteristics of patient specific intervention," Frank C. sciurba, MD, colleagues at the University of Pittsburgh, in an editorial wrote. "Even if the endoscope light source, endoscope high color light source for this method may eventually lead to severe emphysema patients are eligible for treatment, patients may have a more predictable response to treatment. In addition, the efficiency of this improvement can be more cost-effective. Emerging data from larger pivotal trial, support the clinical significance, although palliative care to observe preliminary tests, doctors take care of chronic obstructive pulmonary disease (COPD) doctors should not delay in providing evidence based interventions to provide realistic hope, patient and other options to mitigate their symptoms, improve their quality of life.
