Introduction
In general, whether a 3.0 cm × 5.2 cm pulmonary bulla needs to be surgically removed depends on the specific circumstances. Patients should quit smoking and avoid irritating environments such as dust and smoke. Strenuous exercise, forceful coughing, or breath-holding should be avoided to prevent rupture of the bulla. A balanced and nutritious diet with increased intake of protein-rich foods is recommended to enhance the body's resistance.
Generally, whether a 3.0 cm × 5.2 cm pulmonary bulla requires surgical removal depends on the specific circumstances. The detailed analysis is as follows:
If the pulmonary bulla is located in a critical area or accompanied by obvious symptoms, removal is recommended. When the bulla is situated at the lung periphery, it poses a risk of rupture leading to pneumothorax. If symptoms such as chest tightness, chest pain, or shortness of breath have already occurred and are affecting lung function, surgical removal can reduce the likelihood of complications and improve respiratory function. This is especially important for individuals with a history of pneumothorax, for whom surgery should be actively considered.
Surgical removal is not advised if the bulla is deeply located within the lung, causes no significant symptoms, and the patient is physically frail. If the bulla does not compress surrounding lung tissue or interfere with normal breathing, and if the patient is elderly or has severe heart or lung disease—making surgical risks outweigh potential benefits—conservative management with regular monitoring via imaging studies to track changes in the bulla's size and shape may be preferred.
Patients should avoid smoking and stay away from irritating environments such as dust and smoke. Strenuous exercise, forceful coughing, and breath-holding activities should be avoided to prevent bulla rupture. A balanced, nutritious diet rich in protein is recommended to strengthen the body's immunity. Regular follow-up examinations are essential, and immediate medical attention should be sought if sudden chest pain or difficulty breathing occurs.
