Background: Hemorrhage is a life-threatening complication during bronchoscopic intervention in patients with central airway obstruction (CAO) due to metastatic renal cell carcinoma (RCC). Whether pre-bronchoscopic bronchial arterial embolization (BAE) can reduce the risk of severe bleeding in CAO patients due to metastatic RCC remains unclear. Methods: A total of 31 CAO patients due to metastatic RCC were included retrospectively and divided into a BAE group (receiving pre-bronchoscopic BAE) and non-BAE group in this study. Based on computed tomography (CT) and bronchoscopic findings, tumor debulking was used to reconstruct the airway during interventional bronchoscopy. The primary outcome was the incidence of severe bleeding during bronchoscopic procedures. Bleeding-related complications, Karnofsky performance score (KPS) and dyspnea score were also analyzed over a 1-month observation period. Results: There were no significant differences between the two groups in baseline characteristics, including patients’ features, tumor morphology under CT scannings, tumor site, and obstruction degree under bronchoscopic examination. Procedure-related bleeding occurred in all 31 patients. Pre-bronchoscopic BAE significantly reduced the incidence of moderate and major bleeding when compared with that in the non-BAE group. The incidence of poor visualization and hypoxia was also reduced significantly in the BAE group. There was no significant difference in KPS and dyspnea score between the BAE and non-BAE groups at 1 month follow up. Conclusion: Pre-bronchoscopic BAE might be a feasible option to reduce the risk of severe bleeding for CAO patients due to metastatic RCC during bronchoscopic intervention. Interventional bronchoscopy was a safe and effective procedure for CAO due to metastatic RCC. The reviews of this paper are available via the supplemental material section.

ObjectiveTo evaluate the outcomes of tracheobronchial stenting in patients with malignant central airway obstruction and assist practitioners in palliative settings in understanding the indications, contraindications and management of tracheobronchial stents.MethodsThis retrospective study involved a consecutive case series of palliative patients with central airway obstruction secondary to inoperable cancers who underwent tracheobronchial stenting at a single institution. The European Cooperative Oncology Group (ECOG) scale was used to evaluate patient functional status before and after tracheobronchial stenting.ResultsTwenty-three patients underwent tracheobronchial stenting for malignant central airway obstruction. The majority of patients presented with symptoms of worsening dyspnoea (21 of 23; 91%). Postoperatively, there was a significant improvement in mean ECOG performance status from 2.88±0.34 to 1.58±0.50 (p<0.01). There was no intraoperative mortality resulting from tracheobronchial stenting. Five patients (21.74%) re-presented to hospital due to worsening symptoms and required emergency bronchoscopy. Two patients had stent migration, requiring stent replacement. One patient restenosed from tumour granulation, requiring microdebrider to debulk the mass. Two patients had stent failure secondary to external tumour compression, leading to death.ConclusionTracheobronchial stenting is a safe and effective procedure that offers rapid palliation of symptoms and improvement in patient functional status.
