  • 吸入性肺炎的研究进展

    吸人性肺炎是指口咽部分泌物和胃内容物反流吸入至喉部和下呼吸道, 引起的多种肺部综合征, 吸入量较大时可引起急性化学性吸入性肺炎, 如果吸入量小且将咽部寄植菌带入肺内, 可导致细菌性吸入性肺炎, 常见于老年人、患有神经系统疾病或脑血管病的患者, 是导致老年人死亡的主要危险因素。其他吸入综合征包括气道阻塞、肺脓肿、外源性类脂质综合征、慢性间质性肺炎和偶发分枝杆菌性肺炎等。现将细菌性吸入性肺炎( 简称吸入性肺炎) 的研究进展综述如下。

  • Electromagnetic navigational bronchoscopy compared with transthoracic needle biopsy for diagnostic yield and safety in peripheral pulmonary lesions

    Objective To evaluate the diagnostic yield and safety of two biopsy methods, electromagnetic navigational bronchoscopy (ENB) and transthoracic needle biopsy (TTNB), in peripheral pulmonary lesions. To select a low-risk and high-benefit biopsy method based on the clinical characteristics of the lesions and patients. Methods A retrospective analysis was conducted on inpatients who underwent ENB and/or TTNB for peripheral pulmonary lesions in Huadong Hospital Affiliated to Fudan University. Propensity score matching was used to compare the diagnostic yield and safety of the two biopsy methods. Results A total of 126 patients were included in the ENB group, and 104 patients in the TTNB group. After propensity score matching, 83 matched pairs were obtained. The TTNB group exhibited a significantly higher diagnostic yield compared with the ENB group (90.4% vs. 48.2%, P<0.001), but it was also associated with a higher incidence of pneumothorax (1.2% vs. 21.7%, P<0.001). In the ENB group, the diagnostic efficacy was correlated with lesion diameter (P<0.001, OR=0.183, 95%CI 0.071 - 0.470), but there was no statistically significant difference in the diagnostic yield among different lung segments (P>0.05). In the TTNB group, lesion characteristics did not significantly affect the diagnostic yield, but a lesion diameter ≤30 mm (P=0.019, OR=5.359, 95%CI 1.320 - 21.753) and a distance from the pleura ≥20mm (P=0.030, OR=6.399, 95%CI 1.192 - 34.360) increased the risk of pneumothorax. When stratified based on lesion and patient blood characteristics, no significant difference was found in the diagnostic yield between the two groups for characteristics such as left upper lobe (P=0.195), right middle lobe (P=0.333), solid with cavity (P=0.567), or abnormal serum white blood cell count (P=0.077). However, the incidence of pneumothorax in the TTNB group was higher than that in the ENB group. Conclusions The diagnostic yield of ENB is affected by the size of the lesion, while the incidence of pneumothorax in TTNB is influenced by both lesion size and distance from the pleura. In cases with lesions located in the left upper lobe, right middle lobe, solid with cavity, or with abnormal serum white blood cell count, selecting ENB for biopsy is considered preferable to TTNB.
