    Abstract:
    BACKGROUND: There is growing evidence to support bronchoscopic resection of well-circumscribed typical carcinoids. However, massive bleeding and risk of recurrence can potentially complicate this approach. OBJECTIVES: The aim of this study was to assess the safety and feasibility of endobronchial resection of carcinoids preceded by bronchial artery embolization. METHODS: Five patients with centrally located typical carcinoids were recruited, 4 with a curative intent and 1 for palliation of a carcinoid with mediastinal invasion. All patients underwent selective embolization of the feeding bronchial artery 24-48 h prior to endobronchial resection, which was performed with a rigid bronchoscope and neodymium:yttrium-aluminium-perovskite laser. RESULTS: Minimal bleeding was noted during tumour resection. After a median (range) follow-up of 20 (14-48) months, only the case with segmental extension of the tumour had local recurrence, which was treated successfully using cryotherapy (with negative endobronchial biopsies since), and no cases of metastatic spread occurred. One patient, in whom the histopathological diagnosis was changed from typical to atypical carcinoid following resection, went on to have a surgical bilobectomy 3 months later. Extensive fibrosis was noted at the site of original tumour resection with no evidence of residual disease. CONCLUSIONS: Bronchial artery embolization prior to endobronchial resection of centrally located carcinoids is feasible and safe. The reduction in bleeding may facilitate and simplify the procedure. The possible application of this combined therapy to the management of atypical carcinoids warrants the design of a larger prospective clinical trial.
