Central Airway management
PP08
Introduction: Central airway obstruction (CAO) is a high mortality and multiple etiology’s pathology: endobronchial clos, foreing bodies and thoracic neoplasms. Cryorecanalization has been proposed as an immediate and cheap technique with a low complication rate and immediate improvement.
Methods: Retrospective observational study of therapeutic bronchoscopies with CAO and cryorecanalization employment performed between 2015-2020. Anthropometric data, pulmonary function tests, endoscopic findings and procedure success were obtained.
Results: Sample of 62 procedures. Prototype patient: male (92%) with a mean age of 66 years old. The CAO etiology was varied: malignant neoplasms, endobronchial clots, benign neoplasms, mucous plugs and foreing bodies (69, 16, 6, 6, and 1% respectively). The procedure was performed with flexible bronchoscope in 69% of the cases. Endoscopic success (improvement at least 50% of CAO) was achieved in 92% of the cases. A sub analysis allowed identifying a higher unobstruction (improvement at least 80% of CAO) comparing cryorecanalization in monotherapy vs combination of endoscopic techniques groups (69% vs 53%). (Table 1) Pulmonary function test (measured by FEV1) showed a 14% mean improvement (pre intervention 58% vs post intervention 73%). Subjective dyspnea improvement was also obtained in 82% of the cases (mean 1.14 points on the mMRC scale). Finally, we observed a relationship between time until desobstructive bronchoscopy and endoscopic success: patients with CAO less than 30 days showed a statistically significant higher endoscopic success (71.4% VS 45%).The endobronchial bleeding was the only complication observed (mild 11%, moderate 1%, and severe 1,6%)
Conclusion: Cryorecanalization achieves partial repermeabilization (improvement at least 50% of CAO) and complete (improvement at least 80% of CAO) in 91% and 62% of the cases respectively. In our sample, cryorecanalization was associated with dyspnea and lung function test improvement. Endobronchial cryorecanalization did not show serious complications despite endobronchial bleeding during the procedure in 1⁄4 patients.
