电子支气管镜检查85例碳沫沉积患者病因分析

Analysis of 85 cases with carbon deposits by electronic bronchoscopy combined pathological diagnosis

目的分析电子支气管镜下气管内碳沫沉积的相关病因。方法选择2013年1月至2013年12月在解放军总医院呼吸科介入肺脏病中心行气管镜检察镜下碳沫沉积的患者85例,结合患者一般情况、病理学检查结果进行分析。结果碳沫沉积患者出现临床症状的年龄为50~80岁,平均年龄67.5岁,高发年龄集中在60~80岁,占整组比例的82%,且女性发生率高于男性。碳沫沉积与烟尘接触史有关,76.5%患者接触过煤炭、烟尘;沉积部位不确定,累及单个肺段患者占56.5%,多个肺段受累患者占43.5%;活检病理学结果显示,改变以炎症为主患者占71.2%(P<0.05)。结论研究发现碳沫沉积患者的病理学改变以炎症为主,提示对碳沫沉积部位的活检缺乏特异性,仍有待于进一步研究。

Objectives To explore the cause of airway deposition of carbon foam by electronic bronchoscopy. Methods From January 2013 to December 2013,85 patients with carbon deposits dignosed by bronchoscopy in The PLA General Hospital. Analysis of the relationship between the general condition of the patients and the pathology results. Results The clinical symptoms of carbon deposits appear in 50-80 years old,mean age 67.5 years old,Peak appears at 60-80 years old,accounting for 82% of the whole group,and the incidence of women is more than men. Carbon deposits and smoke exposed history are related,76.5% of patients in contact with smoke. Deposition site is uncertain,involving a single lung segment accounted for 56.5% ,involving multiple lung segment accounted for 43.5% . After biopsy,the pathology is mainly inflammation. Conclusions Our study found that pathological changes in patients who had carbon deposits is mainly inflammation. Biopsy in the carbon deposits is no specificity.
