Conditions

peripheral pulmonary lesion

Interventions

1) Before performing the examination, a chest CT scan is taken in the supine and lateral recumbent positions to create virtual bronchoscopic images
CT analysis software (VINCENT) is used to compare bronchial order numbers, measure bronchial inner diameter, and compare lung lobe volumes. 2) During bronchoscopy, the patient is initially placed in
s position with a suppression band, etc. At the end of bronchoscopy, the patient should be returned to the supine position to complete the examination.

Eligibility

Sex/Gender
All

Inclusion criteria

Inclusion criteria: 1) Patients requiring bronchoscopy for lung cancer, pneumonia, etc. 2) Patients must have peripheral lesions. 3) Must be at least 20 years old. 4) SpO2 greater than 90%. 5) Written consent to participate in the study has been obtained from the patient.

Exclusion criteria

Exclusion criteria: 1) Cases in which bronchoscopy seems to show lesions more central than the subareolar branch. 2) Patients with serious complications that may interfere with the examination. 3) Pregnant women. 4) Patients with other complications that may seriously interfere with the performance of the examination.

Design outcomes

Primary

MeasureTime frame
Compare bronchial order and bronchial inner diameter to lesions in the supine and side lying positions using VINCENT and virtual images.

Secondary

MeasureTime frame
1. Comparison of lung lobe volumes in the supine and lateral recumbent positions Measured using VINCENT 2. Bronchoscopy in supine and lateral recumbent position Agreement with VINCENT and virtual images Insertion bronchial site and order Observed bronchus site and order 3. EBUS findings 4. Combi-beam CT findings and number of imaging Diagnosis rate Diagnosis rate (culture, cytology, and histology combined) and tissue diagnosis rate Diagnosis rate by final diagnosis (benign/malignant) Diagnosis rate by lesion size (2 cm or smaller) Diagnosis rate by distance of lesion from the pulmonary hilum (middle 1/3, outer 1/3) Diagnosis rate by lung lobe Diagnosis rate by presence or absence of involved bronchus 6.
