Ethics Committee Approval
This study was approved by the institutional review board of Hokkaido University Hospital (project approval number 008–0050), and all patients provided written informed consent.
Patients
We performed a retrospective chart review of patients referred to the Hokkaido University Hospital between April 2003 and June 2010 who underwent EBUS-GS. EBUS-GS was performed for 876 lesions during the study period (Fig 1). Six hundred sixty lesions were finally diagnosed as malignant lesions. Thirty-eight lesions were
Patient Characteristics and Benign Pulmonary Diseases Diagnosed With Bronchoscopy
The mean age of 159 patients (97 men, 62 women) was 61.8 years (range, 21 to 85 years). The diameter of the lesions was 26.6 ± 12.9 mm (mean ± SD; range, 6 to 69 mm); 57 lesions were located in the right upper lobe, 19 lesions were located in the right middle lobe, 42 lesions were located in the right lower lobe, 26 lesions were located in the left upper lobe, and 27 lesions were located in the left lower lobe. We performed 5.2 ± 1.9 biopsies (mean ± SD; range, 0 to 9) per pulmonary lesion. One
Comment
This report defines the diagnostic yield of benign pulmonary diseases, especially nodular lesions, when using bronchoscopy with EBUS-GS. By applying the classification of the contribution, we have focused on more details of the diagnostic steps in various types of benign pulmonary nodules. In combination with EBUS-GS, we have had a relatively higher diagnostic yield of 58% (grade A or B) for the diagnosis of benign pulmonary nodules. Our study has shown that bronchoscopy with EBUS-GS is

Probe-based optical fiberscopy for the direct observation of peripheral pulmonary lesions
2019, Respiratory InvestigationCitation Excerpt :Even among patients who were not fully diagnosed histologically or bacteriologically via bronchoscopic sampling, the characteristic findings of malignant and benign PPLs were observed in the malignant and benign groups, respectively. When PPLs remain undiagnosed, which often occurs with benign PPLs because these exhibit an inherent difficulty of diagnosis when using bronchoscopic sampling alone [23], probe-based optical fiberscopy may help clinicians select subsequent steps for obtaining a final diagnosis. Invasive examinations or treatments (e.g., surgical resection) that are unnecessary for benign PPLs, as well as conservative follow-up CT scans that carry a risk of progression for malignant PPLs, may be avoided on the basis of the findings of probe-based optical fiberscopy.
A review of existing and new methods of bronchoscopic diagnosis of lung cancer
2019, Respiratory InvestigationCitation Excerpt :Therefore, it should be acknowledged that the diagnostic rate depends on the number of patients with lung cancer. The diagnostic yield of EBUS-GS for benign pulmonary disease was retrospectively analyzed by our group [14]. The diagnostic rate of benign disease was 55%, which was lower than that of malignant disease.
Study design and rationale: A multicenter, prospective trial of electromagnetic bronchoscopic and electromagnetic transthoracic navigational approaches for the biopsy of peripheral pulmonary nodules
2018, Contemporary Clinical TrialsCitation Excerpt :Based on our pilot data [9] and review of the literature we hypothesize a conservative diagnostic yield of 70% in the staged approach. After review of current published diagnostic yields of 1–3 cm nodules [14, 18–26], the estimated diagnostic yield of historical controls is 59% (historical data on 665 patients out of which 385 had a successful biopsy). To achieve 80% power to detect a difference between the group proportions of 11% (70% versus 59%), a sample size of 149 will be needed in this single-arm trial.
Newer Modalities in the Work-up of Peripheral Pulmonary Nodules
2013, Clinics in Chest MedicineCitation Excerpt :Of note, even for nodules less than 30 mm, the diagnostic yield of R-EBUS–TBBx approaches close to 80%.90,93,95,97–99 Recently published retrospective data on the yield of R-EBUS for benign peripheral processes revealed a significantly higher yield compared with historical controls (58% vs 28%).100 In fact, in a prospective randomized pragmatic trial comparing the effectiveness of R-EBUS–TBBx and the CT-guided percutaneous needle biopsy (PNB-TTNA) in the work-up of PPN, the diagnostic accuracy of R-EBUS–TBBx was shown to be no inferior to that of CT-guided PNB-TTNA and with a significantly lower complication rate.101
