Abstract

Background : Bronchial anthracofibrosis usually manifest as a form of obstructive airway disease, and can be accompanied by parenchymal diseases such as pneumonia, and pulmonary tuberculosis. This study investigated the ventilatory dynamics according to the severity of bronchial stenosis in patients with bronchial anthracofibrosis. Method : One hundred and thirteen patients with bronchial anthracofibrosis that was confirmed by bronchoscopy and who had undergone a pulmonary function test were enrolled in this study group. The correlation coefficients between the pulmonary functional parameters and the number of lobes with bronchial stenosis were investigated. Results : The incidence of ventilatory dysfunction was 56(49.6%) for obstructive, 8(7.1%) for restrictive, 2(1.8%) for mixed, and 47(41.6%) for a normal pattern. The $FEV_1/FVC$, $FEF_{25{\sim}75%}$, $FEF_{25%}$, $FEF_{50%}$, $FEF_{75%}$, and PEF showed a significant negative correlation (p<0.05) and the Raw had a significant positive correlation with the number of lobes with bronchial stenosis(p<0.001). Conclusion : These findings suggest that the most common abnormality of the ventilatory function in bronchial anthracofibrosis is an obstructive pattern with a small airway dysfunction according to the severity of bronchial stenosis.

연구배경 : 기관지 탄분 섬유화증은 주로 만성기관지염, 만성폐쇄성폐질환, 또는 천식 등과 같은 만성 기도 질환의 형태로 발현되며, 질환의 경과 중에 폐렴, 폐결핵과 같은 실질성 병변들이 동반될 수 있다. 저자들은 기관지 탄분 섬유화증에서 환기장애의 병형별 빈도 및 동반된 기관지 협착에 따른 기도의 환기기능 및 역학을 알아보고자 하였다. 방 법 : 기관지내시경검사 상 기관지 탄분 섬유화증으로 진단받은 환자 가운데 폐기능 검사를 실시한 113례의 환자를 대상으로 폐기능 검사에서 구한 여러 계측치들과 협착을 보인 기관지의 수와의 상관관계를 구하였다. 결 과 : 폐쇄성 환기장애가 56례(49.6%), 제한성 환기장애가 8례(7.1%), 혼합성 환기장애가 2례(1.8%), 그리고 정상환기가 47례(41.6%)였다. 노력성 호기곡선에서 구한 계측치 가운데 $FEV_1/FVC$ 및 $FEF_{25{\sim}75%}$은 상관계수가 각각 -0.208, -0.310으로 협착을 보인 기관지의 수에 따라 유의하게 감소하였다(p<0.05, p<0.005). 기류-용량 곡선에서 구한 PEF, $FEF_{25%}$, $FEF_{50%}$ 및 FEF75%는 모두 낮게 관찰되었으며, 상관계수가 각각 -0.309, -0.303, -0.416, 그리고 -0.318로 협착을 보인 기관지의 수에 따라 유의하게 감소하였다(p<0.05). Raw도 0.477로 협착을 보인 기관지의 수에 따라 유의하게 증가하였다(p<0.001). 결 론 : 기관지 탄분 섬유화증은 협착을 보인 기관지의 수가 많을수록 세소기도 병변과 함께 주로 폐쇄성 환기장애를 나타내는 것으로 생각된다.
