What is a Lung Biopsy?
Normal lung tissue.
- A lung biopsy is a percutaneous lung biopsy. It is used for the diagnosis and differential diagnosis of peripheral lung lesions or diffuse lung lesions. Its indications are: (1) Examination of non-qualitative masses in the lung by fiberoptic bronchoscopy, X-rays, sputum, microbial blood, etc., is particularly suitable for the diagnosis of masses located in peripheral areas. (2) Diffuse lung lesions of unknown cause. Percutaneous lung biopsy can be performed in the presence of pleural adhesions. (3) Localized pulmonary infiltration. (4) Unexplained mediastinal mass.

Clinical significance of lung biopsy
- Abnormal results: (1) Tumor cells can be confirmed by pathological examination of lung biopsy. (2) Tuberculosis granuloma can be confirmed by pathological examination of lung biopsy. (3) Pulmonary biopsy tissue pathological examination shows inflammatory lesions, which are considered to be lung infections. Need to check the crowd: Patients with severe illness in the lungs need to be very prepared for examination and verification.
Precautions for lung biopsy
- Prepare before inspection: (1) Preoperative preparation: "fiber bronchoscopy" and "pleural biopsy". (2) The location of the lesion before surgery should be as accurate as possible. In principle, bilateral TBLB is not performed to prevent bilateral pneumothorax and severely damage lung function. Note during inspection: (1) Try not to do it in the middle lobe or tongue, so as not to damage the interpleural pleura and pneumothorax. (2) Anesthesia requirements are higher than conventional fiberoptic bronchoscopy, and patients are required to be quietly examined. Therefore, pethidine should generally be used before surgery instead of phenobarbital. (3) Instruct the patient to cooperate with the examination, such as inhaling deeply, exhaling, holding breath, etc., and keeping the operation safe. (4) Once the biopsy forceps reach the surrounding area, when the patient complains of pain, stop the operation immediately, change the direction of the biopsy, and avoid pleural damage. (5) Close observation and management of complications such as bleeding and pneumothorax after operation. Not suitable for people: (1) People with severe cardiopulmonary insufficiency. (2) Pulmonary vascular lesions. (3) People with bleeding tendency. (4) Acute respiratory infections and fever. (5) The patient is uncooperative or has an uncontrollable cough.
Lung biopsy process
- (1) Anesthesia. (2) Open the chest. (3) Lung examination. (4) Chest section. (5) Submit for inspection.
