目的:了解儿童气道肿瘤经支气管镜介入治疗的可行性。方法:对2016年11月至2018年3月在首都医科大学附属北京儿童医院住院经支气管镜介入治疗的8例原发性气道肿瘤患儿的临床表现、介入治疗结果和预后情况进行回顾性分析。结果:8例原发性气道肿瘤患儿中，男5例、女3例，年龄4岁8月龄至9岁2月龄。临床表现主要为咳嗽伴喘息6例、咯血3例和反复肺部感染2例，均无淋巴结转移及肺外转移。8例患儿均经支气管镜介入肿瘤切除，对4例富含血流的肿瘤患儿支气管镜介入治疗术前行肿瘤供血处支气管动脉栓塞术。术中及术后未发生大出血、气胸等并发症。4例为低度恶性支气管黏液表皮样癌，2例为炎性肌纤维母细胞瘤，1例为多形性腺瘤，1例为支气管平滑肌梭形细胞瘤。术后随访2~4年，复发3例，其中2例炎性肌纤维母细胞瘤患儿中，1例因病灶位置深行外科切肺治疗，1例联合化疗治疗后病灶稳定；1例黏液表皮样癌介入冷冻治疗后随访中。结论:儿童气道肿瘤临床表现不典型，主要有干咳、喘息、反复肺部感染和咯血等症状。经支气管镜下介入治疗儿童气道内良性和低度恶性肿瘤，是一种可行的选择。“,”Objective:To summarize the clinical manifestations and to evaluate the feasibility of therapeutic bronchoscopy in pediatric primary airway tumors.Methods:The clinical data of 8 children presented with airway tumors in Beijing Children′s Hospital from November 2016 to March 2018 were retrospectively analyzed. Descriptive analysis was used to summarize the outcome and prognosis of these children after interventional bronchoscopy.Results:Among the 8 children, 5 were male and 3 were female, aged from 4 years and 8 months to 9 years and 2 months. The main clinical manifestations were cough and wheezing in 6 cases, hemoptysis in 3 cases and recurrent pulmonary infection in 2 cases, and none of them had lymph node metastasis and extra-pulmonary metastasis. All 8 children underwent bronchoscopic resection of the tumors, and the 4 children with blood-rich tumors had bronchial artery embolization at the blood supply site before the resection. No major bleeding or pneumothorax occurred during or after the operation. Four cases had low grade malignant bronchial mucoepidermoid carcinoma, 2 had inflammatory myofibroblastoma, and the rest two had pleomorphic adenoma and bronchial smooth muscle spindle cell tumor. Postoperative follow-up lasted 2 to 4 years, and 3 had tumor recured. Among the 3 cases, 2 had inflammatory myofibroblastoma who underwent surgical resection of the lesion and combined chemotherapy, respectively; and one had mucoepidermoid carcinoma who was under follow-up after interventional cryotherapy.Conclusions:The clinical manifestations of primary airway tumors in children are atypical. The main clinical manifestations are dry cough, wheezing, recurrent pulmonary infection and hemoptysis. Interventional bronchoscopy is a feasible choice for the treatment of pediatric airway tumors.
