BACKGROUND: Bronchopleural fistulas (BPFs) are severe medical condition with high mortality. When the conventional surgical therapy failed, endobronchial intervention could function as the supplementary option. Several studies reported successful endobronchial managements of BPFs whereas the optimal strategies remain elusive. METHODS: We retrospectively reviewed the medical records of patients with BPFs underwent endobronchial interventions with Vaseline gauze, shape-adjustable silicone plug, sutured silicone tube or covered metallic stent in our institution. RESULTS: From 2018 to 2024, a total of 30 patients (11 females VS. 19 males
mean age 48.03 ± 20.33 years) with primary etiology of tumor (n = 19), empyema (n = 6), gastro-bronchial fistula (n = 1), lung infection with immune suppressed status (n = 1) and spontaneous pneumothorax (n = 3) were treated. Different occlusive materials were placed including covered metallic stent (n = 6), shape-adjustable silicone plug (n = 4), sutured silicone tube (n = 1) and Vaseline gauze(s) (n = 21). The dislocation of devices occurred in two patients with covered metallic stent occlusion. On the first day post procedure, 17 patients (56.7%) had complete resolution of the fistulas, compared with 13 patients (43.3%) had incomplete resolution. At the end of the first week post procedure, 19 patients (63.3%) showed complete resolution and 10 patients (33.3%) with partial resolution, whereas one patient (3.3%) failed to have effective closure of the fistula. The representative computer tomography images showed the closure of fistulas and ameliorated hydropneumothorax. CONCLUSION: Four endobronchial interventional maneuvers, the Vaseline gauze, shape-adjustable silicone plug, sutured silicone tube and covered metallic stent, showed both safe and effective managements for patients with BPFs.
