The first result of this study, with no one through observation concerns the lack of early postoperative mortality


and if acceptable total early and late mortality. As a further result, new blisters appear on the site

such as the severe pneumothorax), but the mortality rate due to respiratory failure within the first year after surgery was also acceptable lasix heart failure

incomplete and conflicting data, do not have a predefined time intervals between the patients, and often include >> << patients with giant bullae and GBE. According to our data, however, were obtained in a prospective way serial number patients seen annually


with clinical and functional assessment within 5 years of observation. Therefore, the data are comparable with those reported recently Shypper



etc. in modern series. Another important result of our study is that routine surgery for the treatment of GBE improves clinical and functional conditions

next period and may be considered to be as a marker of favorable outcome. In addition, dyspnea remained strictly


connected to the bronchial obstruction, as shown in a consistent inverse correlation with FEV, FEV

decreases approximately 200 ml in the third year of observation and then remained fairly stable until the end of the observation period. Considering the difference between the second and fifth year of observation, we observed a decrease in the average of 46


ml / year, slightly below the range (48 to 91 ml / year) observed in patients with COPD. At the end of the fifth year of observation, FEV


still clearly higher than the basic values ​​that reproduce the above behavior dyspnea. Patients who presented with diffuse emphysema at inclusion in the study (group B) were on average more severely ill than patients without


diffuse emphysema (group A) and was the only factor for mortality. Minor differences in static lung volumes may

total lung capacity, TGV, residual volume, FRC) was lower in the group at every step further and D


increased more. There were no significant differences in arterial gas parameters in the blood. Thus, on average >> << suggests that patients in both groups benefit from the transaction, although to varying degrees and in different rooms

total 25 ml while in group B was the average annual decline of 83 ml (eg, progressive functional impairment that was similar in patients with severe COPD). In particular, the group of patients increased FEV


for the first 2 years after bullectomy was over three times lower for the next 3 years. In the group of patients B,


This growth was almost completely offset in subsequent years, which decreases occurred that was similar to


those that occur in patients who underwent LVRS, which inevitably raises questions about when patients should undergo surgery. In calculating the overall correlation between bullectomy and LVRS of the consequences of such an operation at the clinic and


lung function, we can show that the main clinical and functional status of patients who underwent >> << bullectomy for GBE, taken as a whole or undergo LVRS for diffuse emphysema differ markedly. In fact, patients who undergo


LVRS have a higher average age above the average score breathlessness and decreased Pa, D, and FEV


values ​​compared with those undergoing bullectomy. In addition, these patients show surprisingly different mortality rates, as shown by Gehlbach, etc.


of 26 patients observed for 5 years by Naunheim et al


of 330 patients after undergoing unilateral LVRS and in 343 patients after bilateral LVRS observed


for 3 years and, more recently, the National Judicial treatment of emphysema. However, the early functional changes after the surgery qualitatively similar. In particular, in both patients who underwent


bullectomy and in those who underwent LVRS, dyspnea decreases and FEV


increases during the first 6 months after surgery. This improvement more and more consistently in the first group, where it is stored for at least 5 years, while the progressive >> << impaired lung function, as reported, on average, within 1 year after the patient undergoes LVRS. However, in 2003


research has been done in a strictly selected group of patients, LVRS as a result of the positive effects to assess dyspnea and quality

patients with primary diffuse emphysema. .
