[Lung volume reduction surgery. A new surgical therapeutic possibility for patients with emphysema].

Lung volume reduction surgery is a new surgical procedure for treatment of patients with pulmonary emphysema. At the operation the most peripheral parts of the lung are resected. Only 15-20% of the patients admitted for lung volume reduction surgery are suitable for operation. The preliminary results have demonstrated improvement in lung function in the majority of the patients. Most of the reports comprise small numbers of patients and have a short time of observation. The longest reported period of observation for a larger number of patients is 24 months and shows a continuing improvement in lung function, dyspnoea and six minute walk test. Because of the high incidence of emphysema, lung volume reduction is a procedure that could reach large extension in the future. However, better definition of criteria of inclusion and better evaluation of the operative procedures are needed.
