Improved lung function and quality of life following increased elastic recoil after lung volume reduction surgery in emphysema.
Lung volume reduction surgery for severe emphysema with removal of 20-30% of the most destroyed parts of the lung parenchyma has been reported to improve lung function substantially. Increased elastic recoil has been suggested as one underlying mechanism for the improvement. Fourteen patients, seven men and seven women with a mean age of 62 years, who underwent bilateral lung volume reduction surgery have been followed up for 3 months. ⋯ The patients reported a high degree of subjective improvement according to the St. George's Respiratory Questionnaire and the working capacity on a bicycle increased by 26% from a mean of 38 W to 48 W (P < 0.01). The promising short-term results of lung volume reduction surgery for severe emphysema appear to be related to improved pulmonary elastic recoil.

Thoracentesis with a chest tube insertion and drainage of large pleural effusion is widely performed in patients with malignant lung diseases. One potential problem with a conventional chest tube placement is occasional incomplete evacuation of effusion owing to inappropriate position of the tip where the drainage holes opened. ⋯ There were no significant complications. This study suggested that the curved chest tube would be safe and useful in completing drainage of pleural effusion.
