慢性阻塞性肺疾病合并支气管扩张186例回顾性分析

Retrospective Analysis on 186 Cases of Chronic Obstructive Pulmonary Disease and Bronchial Dilation

目的了解住院病人中慢性阻塞性肺疾病合并支气管扩张的发病情况,同时通过回顾性分析,了解其影像学、肺功能及细菌学特点。方法回顾性分析2010年10月至2014年9年期间收治的慢阻肺急性加重期病人917例,通过高分辨率CT、肺功能、痰细菌学检查分析慢阻肺合并支扩的特点。结果高分辨率CT检查发现合并支气管扩张病变人数为186例;其肺功能中重度阻塞性通气障碍为主,部分为混合性通气功能障碍;病原菌以革兰氏阴性杆菌为主。中重度以上慢阻肺患者合并支气管扩张多见,且病原菌检出率高。结论支气管扩张在慢性阻塞性肺疾病中发病率较高,应引起重视。

Objective To understand the occurrence condition of chronic obstructive pulmonary dis-ease（COPD）and bronchial dilation of inpatients and their imaging,pulmonary function of bacteriological characteristics through the retrospective analysis. Methods Nine hundred and seventeen patients of COPD at aggravating stage were treated from October 2010 to September 2014 in the retrospective analysis. The characteristics of COPD and bronchial dilation were analyzed through high resolution CT,pulmonary function and sputum bacteriological examination. Results It was found in high resolution TC that 186 cases were complicated with bronchial dilation,predominated as severe obstructive airway disorder and a part of cases presented mixed obstructive airway disorder. Gram - negative bacilli were the main pathogenic bacteria. The patients with middle or severe COPD are commonly complicated with bronchial dilation and the pathogen de-tection rate was high. Conclusion The occurrence rate of bronchial dilation is high in the patients of COPD and the great attention should be considered.
