Does lung puncture biopsy require hospitalization?

Lung puncture biopsy is a common examination method. After this puncture examination, hospitalization is required, generally at least one week. At this time, the doctor will understand whether the patient has any symptoms of physical discomfort. Lung puncture biopsy is very important for checking lung health. After the examination, the patient should understand the precautions and prevent some complications. Let’s take a look at this aspect.

Does lung biopsy require hospitalization?

Lung puncture biopsy requires hospitalization for examination, and the results are generally available in about seven days. In addition, it also depends on the patient's own clinical symptoms. If the physical signs are good, the patient can be discharged after the results are available. If the examination results determine that surgery is necessary, the patient should be hospitalized promptly and regularly for effective treatment, which will help promote the patient's physical recovery.

Lung biopsy method

1. For lesions of the upper lobe and hilum, puncture is usually performed from the front in the supine position. For lesions of the lingula and middle lobe, puncture is usually performed from the side in the supine position. For lesions of the basal segment and dorsal segment of the lower lobe, puncture is usually performed from the back in the prone position.

2. Select the center of the lesion as the puncture level, and choose the shortest distance (vertical or horizontal distance) from the skin to the lesion as the puncture path, and pay attention to avoid blood vessels, interlobar fissures, and intercostal nerves. When the lesion is located in the posterior segment of the upper lobe apex, an oblique needle insertion is sometimes used to avoid the scapula and ribs.

3. Select the puncture point and path according to the location and size of the lesion shown by CT or fluoroscopy, and mark the puncture point with a marker or gentian violet. The skin at the puncture area is routinely disinfected, covered with a drape, and local anesthesia is performed. Under the guidance of CT or fluoroscopy, the puncture needle is inserted into the lesion, and the patient is asked to hold his breath during needle insertion.

4. After CT or fluoroscopy confirms that the puncture needle tip is in the center of the lesion and there is no necrotic area, pull out the needle core, connect the syringe for negative pressure suction, and pull up the puncture needle to perform multi-point fan-shaped sampling. For solid masses, a cutting needle can be used to obtain specimens.

5. Obtain specimens and send them for pathological examination.

Precautions

1. Postoperative care: Patients need to be observed for 2 to 4 hours after the puncture biopsy. If no abnormalities are found by fluoroscopy, radiography or CT scan, they can go home for observation.

2. Complications ① Pneumothorax: The most common complication. If the lungs are compressed by 20% and symptoms tend to worsen, chest venting treatment is required. ② Bleeding: Mild hemoptysis, advise to rest in bed, take diazepam orally or intramuscularly. Massive hemoptysis can be treated with hemostatic drugs such as vasopressin. ③Air embolism: rare but with serious consequences. During the operation, care should be taken to prevent penetration of the pulmonary vessels, and the cannula needle should be blocked with the needle stylet immediately after each aspiration to prevent air from entering. ④ Tumor metastasis: rare. The needle core should be properly protected by a cannula when the needle is removed to prevent the biopsy material from falling off along the needle track.
