Objective To evaluate the role of guide sheath (GS) utilization in radial endobronchial ultrasound guided transbronchial lung biopsy (EBUS-TBLB) for diagnosis of peripheral pulmonary lesions (PPLs). Methods The clinical data of patients who underwent EBUS-TBLB in Peking University First Hospital from July 2012 to June 2015 were retrospectively reviewed. The patients were divided into three groups,ie. a GS group, a non-GS group, and a double biopsy group. Results A total of 118 patients with 126 PPLs were collected. The overall diagnostic yield of EBUS-guided bronchoscopy was 60.3%. The diagnostic yield of GS group, non-GS group and double biopsy group was 65.4%(36/55), 61.5%(8/13), 59.6%(31/52), respectively. The diagnostic yield of the non-GS group was significantly lower than other two groups when PPLs≤20 mm (χ2=6.8,P=0.033), whereas no significant difference was observed when PPLs>20 mm (χ2=2.301,P=0.301). Conclusion GS significantly improves diagnostic yield in EBUS-TBLB when PPLs≤20 mm.
Peripheral pulmonary lesions (PPLs) are generally considered as lesions in the peripheral one-third of the lung. A computed tompgraphy (CT) guided transthoracic needle aspiration/biopsy or transbronchial approach using a bronchoscope has been the most generally accepted methods. Navigation technique can effectively improve the diagnosis rate of peripheral pulmonary lesions, reduce the incidence of complications, shorten the time of diagnosis, and make the patients get timely and effective treatment.
ObjectiveTo evaluate the role of surgical resection on synchronous multiple pulmonary nodules identified difficultly in clinics.MethodsThe clinical data of 97 patients with synchronous multiple pulmonary nodules who received surgical resection between 2012 and 2019 in Hunan Cancer Hospital were retrospectively analyzed. There were 72 males and 25 females, aged 58.1±9.0 years. Among these patients, there were 78 patients with ipsilateral and 19 patients with bilateral pulmonary nodules. Clinicopathological parameters between main nodules and secondary nodules were evaluated. Perioperative morbidity was also assessed.ResultsThe operation was successfully completed on all patients for the ipsilateral and bilateral lesions. Totally, 71.1% of mian lesions was mostly removed by lobectomy, and the completion rate of video-assisted thoracoscopic surgery (VATS) was 69.1% (67/97); 80.4% of secondary lesions were mostly removed by wedge resection, and the completion rate of VATS was 71.1% (69/97). The incidence of grade 3 or higher complications after unilateral or bilateral surgery was 12.8% and 5.3%, respectively. Postoperative pathology confirmed that the main lesions were malignant in 65 patients (67.0%), mainly adenocarcinoma (63.1%), of which 43.1% were in the stage Ⅰ; 32 patients were benign, mainly tuberculoma (56.3%). There were 29 patients of malignant secondary lesions, 67 benign, and 1 both benign and malignant; the pathological agreement rate of primary and secondary lesions was 54.6% (lung cancer metastases in the lung and all the benign). When the primary lesion was malignant with its diameters of <3 cm, 3-<5 cm, 5-7 cm, >7 cm, the metastatic rate of secondary lesions was 42.5%, 15.8%, 20.0%, 0, respectively. When the primary lesion was malignant with lymph node metastasis, the probability of the secondary lesion being a metastatic tumor was higher than that without lymph node metastasis (46.7% vs. 30.0%, P>0.05). When the primary lesion was malignant and the primary and secondary lesions were located in the same lobe, the secondary lesions were more likely to metastasize (54.5%), while when they were located on different lobes on the same side or different sides, the secondary lesions were more likely to be benign (58.1%, 72.7%), and the possibility of metastasis was small ( 32.6%, 9.1%). When the primary lesion was benign and clinical differential diagnosis was difficult, the secondary lesion was benign.ConclusionFor synchronous multiple pulmonary nodules, the diameter of the primary lesion is large, the metastatic rate of secondary lesions tends to decrease. In ipsilateral synchronous multiple pulmonary nodules, especially with node metastasis, the risk of metastatic nodule increases. Bilateral surgical resection does not significantly increase the perioperative morbidity.
Objective To evaluate the diagnosis value of radial probe endobronchial ultrasound guide sheath transbronchial lung biopsy (RP-EBUS-GS-TBLB) combination with rapid on-site evaluation (ROSE) in peripheral pulmonary lesions (PPLs). Methods One hundred and fifty-eight patients with PPLs identified by computed tomography in Nanjing Chest Hospital underwent RP-EBUS-GS-TBLB with or without ROSE randomly between February 2016 and August 2017. The sensitivity, the procedure time, the biopsy times, and the complications were evaluated in the two groups. Results The diagnostic yield was 85.7% (72/84) in ROSE group and 70.3% (52/74) in No-ROSE group. There was significant difference in diagnostic sensitivity between the two groups (P<0.05). The mean procedure time and number of biopsy in ROSE group were less than those in No-ROSE group (P<0.01). No severe procedure related complications such as pneumothorax and hemoptysis were observed. Conclusions ROSE can improve the diagnostic sensitivity, and shorten the procedure time. RP-EBUS-GS-TBLB combined with ROSE is a safe and effective technique for PPLs.
The detection of peripheral pulmonary lesions has increased gradually with the popularity of CT. Rapid and accurate diagnosis, and individualized treatment are two aspects we need to pay great attention to. These situations also raise higher request for the technique in diagnosis and treatment. At present, the commonly used transthoracic methods can increase the risk of complications such as pneumothorax and bleeding. The newly bronchoscopic approaches for diagnosis and treatment make less injury via natural lumen and have been applied widely in clinics. This review will introduce the worth expecting progress in bronchoscopic diagnosis and treatment for 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.
Objective To systematically review the value of rapid on-site evaluation (ROSE) for diagnosing pulmonary and mediastinal lesions with endobronchial ultrasound (EBUS). MethodsPubMed, EMbase, The Cochrane Library, Web of Science, CNKI, Wanfang, and VIP databases were searched by computer to collect the studies of ROSE and EBUS in the diagnosis of pulmonary and mediastinal lesions from inception to August 2022. Two researchers independently screened the literature, extracted the data, and evaluated the risk of bias in the included studies. Meta-analysis was implemented by RevMan 5.4 and Stata 12.0 software. ResultsA total of 15 studies (9 retrospective studies and 6 prospective studies) with 3 577 patients were included. The meta-analysis results of main outcomes showed that the adequacy of the sample (RD=0.10, 95%CI 0.05 to 0.15, P<0.000 1), overall diagnosis rate (RD=0.07, 95%CI 0.04 to 0.10, P<0.000 1) and the diagnosis rate of the malignant lesion (RD=0.06, 95%CI 0.02 to 0.09, P=0.004) of the ROSE combined with EBUS group were significantly higher than those of the EBUS group. Subgroup analysis showed that the diagnosis rates of pulmonary lesions (RD=0.12, 95%CI 0.08 to 0.17, P<0.000 01) and mediastinal lesions (RD=0.06, 95%CI 0.01 to 0.12, P=0.02) in the ROSE group was significantly higher than those in the EBUS group. The overall diagnosis rate and malignant diagnosis rate of ROSE combined with EBUS were 90% and 92%. The meta-analysis results of secondary outcomes showed that the number of lesions punctures (MD=–1.16, 95%CI –1.89 to –0.43, P=0.002) in the ROSE combined with EBUS group were significantly less than that in the EBUS group; there was no statistical difference in operation time (MD=0.09, 95%CI –5.22 to 5.39, P=0.97) or incidence of complications (RD=–0.06, 95%CI –0.13 to 0.01, P=0.1) between the two groups. Conclusion ROSE can improve the diagnostic efficiency of EBUS in pulmonary and mediastinal lesions, and has the value of the clinical application.
