摘要

目的

分析经支气管冷冻肺活检(transbronchial cryobiopsy，TBCB)诊断的具有自身免疫特征的间质性肺炎(interstitial pneumonia with autoimmune features，IPAF)病例资料，评价TBCB诊断IPAF的有效性及安全性。

方法

从2015年4月至2018年12月，针对原因不明的间质性肺疾病(interstitial lung disease

ILD)患者实施TBCB检查并从中筛选出符合IPAF诊断标准的病例，收集并分析其临床、影像学及病理资料，评价TBCB对IPAF的诊断效能，记录TBCB的并发症。

结果

从83例接受TBCB检查的患者中，采用临床-影像-病理诊断模式(clinico-radiologic-pathologic diagnosis，CRP)筛选出15例符合诊断的IPAF病例，而采用临床-影像模式(CR)仅筛选出8例符合诊断的IPAF病例。TBCB检查时间为(31.7±14.2) min，取得的标本大小为10(7，15) mm

。1例患者在术后发生轻度气胸

经过吸氧后气胸吸收；15例患者术中出现不同程度出血(轻中度出血14例，重度出血1例)，经止血处理后出血停止。IPAF患者呼吸系统主要症状为咳嗽和呼吸困难，免疫系统表现有技工手、雷诺现象、口干眼干等。血清学检查以抗核抗体阳性及

抗R0-52抗体阳性常见，分别有12例(80.0%)和10例(66.7%)。肺功能以弥散功能下降为主，6 min步行距离为(388.5±88.4) m。胸部高分辨率CT(high resolution computed tomography

HRCT)及病理学检查以非特异性间质性肺炎(non-specific interstitial pneumonia

NSIP)表现为主。

结论

TBCB可提高IPAF诊断率且具有良好的安全性。

Abstract

Objective

To evaluate the effectiveness and safety of transbronchial cryobiopsy (TBCB) in the diagnosis of interstitial pneumonia with autoimmune features (IPAF).

Methods

From December 2015 to December 2018

TBCB was performed in the patients with interstitial lung disease of uncertain origin. The cases within the IPAF diagnostic criteria were selected

and their clinical

radiological and pathological data were collected and analyzed to evaluate the diagnostic effect of TBCB for IPAF. The complications of TBCB were recorded.

Results

Among the 83 cases undergoing TBCB

15 eligible IPAF cases were screened out by a mode of clinical-radiological-pathological diagnosis (CRP)

while only 8 cases were diagnosed as IPAF with clinical-radiological diagnosis (CR). It took averagely 31.7±14.2 min for TBCB procedure

and the medium area of the obtained specimens was 10 (7

15) mm

. One patient developed mild pneumothorax after the procedure

which was absorbed after oxygen inhalation. Hemorrhage of different volumes occurred during the procedure (1 case of severe hemorrhage) in 15 patients

which was controlled with hemostatic measures. The common initial symptoms were cough and dyspnea. The most common manifestations in immune system were technician hand

Raynaud phenomenon

and dry mouth and dry eye and so on. Serological tests were positive to antinuclear antibodies in 12 cases (80%) and to anti-R0-52 antibodies in 10 cases (66.7%). The main pulmonary function deficiencies were decrease in diffuse function

and the average 6-minute-walking distance was 388.5±88.4 m. The main features on chest

high resolution computed tomography (HRCT) and pathological examination were as those of non-specific interstitial pneumonia (NSIP).

Conclusion

TBCB improves the diagnostic rate of IPAF with a satisfactory safety.
