Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Pulmonary nodules are small in size and easy to move with breathing. CT guided puncture is highly dependent on the personal experience of physicians, that is, the accuracy, efficiency and incidence of complications of puncture vary greatly among physicians.

Puncture template (PT) assisted CT guided needle biopsy of pulmonary nodules has good clinical feasibility, which is expected to make up for the deficiency of simple CT guided needle biopsy, and make the needle biopsy of pulmonary nodules more accurate and standardized.

This study intends to carry out a randomized controlled study to further evaluate the safety and effectiveness of PT assisted CT guided needle biopsy of pulmonary nodules, and provide higher quality data reference for its clinical application.

Patients were randomly divided into two groups: PT assisted CT guided or simple CT guided lung biopsy. The operation related information, complications and postoperative pathological results of the two groups were collected.

Primary end point: puncture accuracy Secondary end point: success rate of first needle puncture; complication rate (such as pneumothorax, bleeding, etc.); operation time; CT scan times; pathologic findings.

Puncture Template and CT group

Puncture Template assisted CT guided lung biopsy was performed.

Group Type EXPERIMENTAL

CT guided biopsy for pulmonary nodule

Intervention Type BEHAVIORAL

The technical process of the experimental group: ① design of puncture path, positioning and fixation of patients; ② puncture point positioning; ③ installation of navigation frame and template; ④ percutaneous lung biopsy guided by PT combined with CT.

The technical process of the active comparator group: ① planning puncture path, positioning and fixation of patients; ② positioning puncture point; ③ CT guided percutaneous lung biopsy.

The operation related information, complications and postoperative pathological results were collected.

CT group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Single or multiple pulmonary nodules (solid, partially solid, pure ground glass), with the maximum diameter of 5mm to 20mm and need for pathological diagnosis.
* No drugs affecting blood coagulation and (or) platelet aggregation were used; if used, the drugs had been stopped for enough time according to the drug elution period.
* KPS \> 60, no serious or uncontrollable underlying diseases, the patients can tolerate lung puncture according to clinical evaluation.
* There is an appropriate puncture path.

Exclusion Criteria

* Poor lung function (such as FEV1 \< 40% in the first second and / or DLCO \< 50%) and / or isolated pulmonary bullae on the puncture path.
* The nodule is close to small airway and blood vessels, or has pulmonary hypertension and superior vena cava compression, so the risk of puncture bleeding and hemoptysis is expected to be high.
* Poor compliance, unable to complete the cooperation.
* Due to other reasons which is not suitable to participate in this clinical trial.
