Brief Summary

This is a randomized controlled trail aiming at comparing the diagnostic value and safety of endobronchial ultrasonography with a guide sheath(EBUS-GS) and computed tomography-guided transthoracic needle biopsy(CT-TTNB) for peripheral pulmonary lesions (PPLs). Patients eligible for the inclusion criteria are diagnosed using either EBUS-GS or CT-TTNB randomly. The diagnostic indicators such as sensitivity, specificity, and accuracy are compared between the two groups. Post-procedure complications are recorded.

Outcome Measures

Primary Outcomes (1)

• Safety. It is measured by the incidence rate of all adverse events during or after EBUS-GS or CT-TTNB.

  Adverse events include: 1)pneumothorax or pulmonary hemorrhage which are observed in CT scan after CT-TTNB; 2)patient's complaint of chest pain or dyspnea after returning the ward, and bedside X-ray shows pneumothorax or decreased respiratory auscultation，and drainage should be performed; 3)postoperative hemoptysis and usage of hemostatic agents;4)severe chest pain, but no pneumothorax in chest film, no T wave or ST segment changes in ECG,and analgesics should be used;5)new tumor or subcutaneous nodules are found in the needle channel during the follow-up;6)other adverse events: such as pleural reaction; arrhythmia, continuous hypoxemia or persistent hypotension during anesthesia process; hoarseness after EBUS-GS,and cricoarytenoid joint dislocation is found by laryngoscope.

Interventions

EBUS-GS PROCEDURE

The equipment for EBUS-GS includes super-thin bronchoscope BF-P260F, endobronchial ultrasonic system EU-M30S, ultrasonic probe UM-S20-17S, and guided sheath kit K201. All facilities are provided by Olympus Co. The EBUS-GS procedure was performed by thoracic surgeons. The patient was in supine position, under general anesthesia, and provided ventilatation through laryngeal mask. First, the operator placed super-thin bronchoscope into the bronchus of interest, inserted the probe covered with GS through a work channel. Later, adjusted the bronchoscope and probe to obtain classical ultrasonic graphs. The assistant fixed the bronchoscope, pulled the probe out, and placed the brush and biopsy forceps, respectively, through the GS. This process was assisted using x-ray fluoroscope or not.

EBUS-GS

CT-TTNB PROCEDURE

The devices for CT-TTNB includes Lightspeed VCT spiral CT(GE co.) and Quickcore(COOK Co.) biopsy kit. The kit includes a sheath(5cm in length and 16G in outer diameter) and a automatic biopsy needle(15cm in length and 18G in outer diameter). The patient stays in supine, prone or lateral position according to the lesion's location. The first chest CT scan is performed to confirm the location of the lesion and make an optimal entry point. Then, after sterilization and 2% lidocaine local anesthesia, the sheath is stabbed into chest wall through the entry point. The second CT scan is performed to make sure that the sheath stays in proper angle and depth. The operator places the needle through the sheath and enter the lesion. Then fire the biopsy needle and repeat the procedure twice or third time. The last CT scan is conducted to determine whether pneumothorax or hemorrhage occurred.

CT-TTNB

Eligibility Criteria

• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

• Lesions presented as nodule or mass in CT imaging and located at the distal end of the segmental bronchus; invisible under normal bronchoscope; no pathological results were obtained before biopsy procedure; patients can tolerate video assisted thoracic surgery(VATS) lobectomy or wedge resection; all patients provided written informed consent.

You may not qualify if:

• Presence of central pulmonary lesion and visible under the bronchoscope; lesions presented as exudative or consolidation in CT imaging; the location was unsuitable for CT-guided biopsy; presence of pneumothorax or pleural effusion patients have contraindication for EBUS-GS or CT-TTNB,such as cardiopulmonary dysfunction, cachexia, thrombocytopenia or coagulopathy.
