Background: This study aims to present our experience with endobronchial coils in patients who underwent endobronchial lung volume reduction due to advanced emphysema.

Methods: The study included 46 patients (45 males, 1 female; mean age 61.7±8 years; range, 43 to 80 years) who underwent endobronchial lung volume reduction with endobronchial coils for advanced emphysema. Patients" age, gender, pulmonary function tests, post-treatment morbidity, mortality, pre- and post-treatment (6 months) six-minute walking distance, modified Medical Research Council dyspnea scores, chronic obstructive pulmonary disease assessment test and Hospital Anxiety and Depression Scale scores were recorded.

Results: Patients had an average of 65 pack/year smoking history. An average of 11 (range, 9-15) coils were placed per lobe (right upper lobe=35, left upper lobe=19, right lower lobe=2, left lower lobe=4). Mean follow-up duration was 12.6 months (±5.6 months). Post-treatment forced expiratory volume in one second, residual volume and six-minute walking distance values were improved with statistical significance. Also, significant improvement was seen in quality of life, quantified by modified Medical Research Council, chronic obstructive pulmonary disease assessment test and Hospital Anxiety and Depression Scale scores. While no immediate major postoperative complications occurred, three patients developed chronic obstructive pulmonary disease exacerbation, two developed pneumonia, and one developed recurrence of previous neurologic disorder within 30 days.

Conclusion: Endobronchial coil administration provides lower morbidity and mortality compared to lung volume reduction surgery as well as significant improvement in pulmonary functions and quality of life in selected patients with advanced emphysema.
