Background. Lung volume reduction surgery (LVRS) has been demonstrated to provide symptomatic relief and to improve lung function in patients with end-stage emphysema. The goal of this study was to assess the additional morbidity associated with lung transplantation after LVRS for end-stage emphysema with regard to immediate postoperative outcomes, longitudinal spirometry, and survival rates compared to an age-, gender-, procedure-matched, and transplant time-matched cohort that had lung transplantation alone.
Methods. We compared the postoperative and long-term outcomes of a sequential procedure cohort to a matched cohort to assess the possible added post-transplant morbidity.
Results. Fifteen patients who underwent sequential LVRS (including 11 unilateral LVRS, 4 bilateral LVRS) and lung transplantation (ipsilateral in 7 and contralateral in 8) on average 28.1 ± 17.2 months (median, 27.4 months; range, 3.7 to 61.7 months) later were assessed. No significant differences were noted in pretransplant demographics, post-transplant variables, longitudinal spirometric indices, or survival. A trend toward a lower pretransplant arterial carbon dioxide tension was apparent in the sequential procedure cohort. Group analysis revealed a significant increase in the number of patients requiring transfusion and in the total number of units transfused in patients undergoing ispsilateral transplantation after LVRS; a significant increase in the length of intensive care unit stay; and a trend toward an increase in the duration of hospital stay in patients undergoing lung transplantation within 18 months of LVRS.
Conclusions. In appropriate candidates, LVRS bridged the time to transplantation by an average of 28.1 ± 17.2 months (median, 27.4 months; range, 3.7 to 61.7 months) without significantly increasing post-transplant morbidity or mortality. Furthermore, bilateral LVRS bridged the time to transplantation to a greater extent than unilateral LVRS (34.9 ± 29.8 months; median, 32.1 months versus 25.4 ± 16.3 months; median, 22.3 months; p = 0.23).
