Purpose
Air leaks are common after lobectomy, segmentectomy, and lung volume reduction surgery (LVRS). This can increase post-operative morbidity, cost, and hospital length of stay. The management of post-pulmonary resection air leaks remains challenging. Minimally invasive effective interventions are necessary. The Spiration Valve System (SVS, Olympus/Spiration Inc., Redmond, WA, US) is approved by the FDA under humanitarian use exemption for management of prolonged air leaks.
Methods
This is a prospective multicenter registry of 39 patients with air leaks after lobectomy, segmentectomy, and LVRS managed with an intention to use bronchoscopic SVS to resolve air leaks.
Results
Bronchoscopic SVS placement was feasible in 82.1% of patients (32/39 patients) and 90 valves were placed with a median of 2 valves per patient (mean of 2.7 ± 1.5 valves, range of 1 to 7 valves). Positive response to SVS placement was documented in 76.9% of all patients (30/39 patients) and in 93.8% of patients when SVS placement was feasible (30/32 patients). Air leaks ultimately resolved when SVS placement was feasible in 87.5% of patients (28/32 patients), after a median of 2.5 days (mean ± SD of 8.9 ± 12.4 days). Considering all patients with an intention to treat analysis, bronchoscopic SVS procedure likely contributed to resolution of air leaks in 71.8% of patients (28/39 patients). The post-procedure median hospital stay was 4 days (mean 6.0 ± 6.1 days).
Conclusions
This prospective registry adds to the growing body of literature supporting feasible and effective management of air leaks utilizing one-way valves.
