Abstract
BACKGROUND
Bronchoscopic lung volume reduction (BLVR) by either the endobronchial valve (EBV) or coil (EBC) procedure is recommended for severe emphysematous patients. BLVR applications generally help healthy lung areas ventilate more comfortably by reducing the hyperinflation and improving the contraction capacity of diaphragm.
OBJECTIVES
Compare our experience with valve and coil BLVR devices.
DESIGN
Retrospective.
SETTING
Single tertiary care centre.
PATIENTS AND METHODS
Demographic data, vital signs, pulmonary function tests (PFTs), the six-minute walking test (6MWT), vital signs, arterial blood gases and complications were recorded.
MAIN OUTCOME MEASURES
Change in PFTs and completion of the 6MWT.
SAMPLE SIZE
60 Turkish men with a diagnosis of chronic pulmonary lung disease.
RESULTS
Clinical and demographic characteristics were similar in patients who underwent EBV and EBC. Thirty (96.8%) EBV patients and 27 (93.1%) of the EBC patients were able to properly complete the PFT before the procedures, but all complied after the procedures. Significant improvement in PFTs were achieved after the procedure and there were no statistically significant differences in post-procedure performance. For the 6MWT, the completion rate improved from 15 (48.4%) to 19 (61.3%) patients in the EBV patients (P=.125) and from 19 (65.5%) to 21 (72.4%) patients in the EBC patients (P=.500). There was no significant difference in completion rates for the walking test for either group (median 32 meters in EBV patients and 37 meters in EBC patients; P=.652). Vital signs and arterial blood gases were similar in the two groups. The rates of complications were similar in both groups.
CONCLUSION
Endobronchial valves and coils are safe and effective methods for BLVR for patients with severe emphysema.
LIMITATIONS
Relatively small sample, retrospective design, single-centre retrospective study.
CONFLICT OF INTEREST
None.
