Pneumothorax refers to the condition where gas enters the pleural cavity. Normally, the pleural cavity is a sealed space formed by the visceral pleura covering the lung surface and the parietal pleura on the chest wall. When gas enters the pleural cavity due to some reason, causing a state of gas accumulation, it is called pneumothorax. The causes of pneumothorax can be diseases of the lungs themselves or gas produced after the lungs and chest wall are injured by external forces. Typically, the condition occurs when the pleura near the lung surface ruptures, allowing gas to enter the pleural cavity, which is referred to as pneumothorax.

What are the main signs of pneumothorax?

If it is a small amount of pneumothorax, the physical signs are generally not obvious, especially when patients with emphysema develop pneumothorax, it is difficult to detect any signs. However, when a larger amount of pneumothorax occurs, inspection will reveal that the affected side of the chest is bulging and respiratory movements are reduced. Upon palpation, the trachea usually shifts towards the healthy side, tactile fremitus on the affected side is reduced, percussion results in hyperresonance or tympany, and auscultation shows reduced breath sounds, which can disappear in severe cases.

How to treat recurrent pneumothorax for the second time?

Patients with recurrent pneumothorax, we recommend proactive minimally invasive surgical intervention. For patients experiencing their first recurrence of pneumothorax, the likelihood of a second recurrence is about 20-30%. For those who have had two episodes of pneumothorax, it indicates the presence of a small rupture on the lung, or an area that has not healed well, or is particularly weak. Thus, for patients who have had two episodes or a second occurrence of pneumothorax, if they do not receive active treatment, the probability of a third recurrence rises to about 70-80%. Whether using minimally invasive surgery or the conservative method of simple tube insertion, both are certainly burdensome for the patient. However, for patients with a second occurrence of pneumothorax, undergoing a small minimally invasive surgery, which involves a small incision of one to two centimeters under the armpit to treat the pneumothorax, dramatically reduces the likelihood of subsequent occurrences from the previous 70-80% to below 10%. Therefore, the best treatment for a second pneumothorax episode is through minimally invasive surgical intervention.

Can pneumothorax measure lung capacity?

Pneumothorax is a very common type of disease, caused by many and complex factors. It is classified into three different types based on individual conditions, so different types of pneumothorax lead to different clinical symptoms and consequences for the patient. Usually, it is not advisable to measure lung capacity immediately after a pneumothorax occurs. For lighter cases, it is recommended to wait at least half a month before measuring lung capacity. If the pneumothorax is severe, the interval may need to be over a month before conducting lung capacity measurements. Therefore, while patients with pneumothorax can have their lung capacity measured, this should only be done once the condition is effectively managed.

Pneumothorax should be registered under which department?

What department should you register for pneumothorax? If pneumothorax occurs suddenly, the condition is generally severe with significant breathing difficulties. In such cases, we recommend prioritizing a visit to the emergency department. Once the emergency department receives the patient, they will immediately request a consultation with a thoracic surgeon or a respiratory specialist. If the patient requires surgery, such as thoracic closed drainage or other procedures, it is usually handled by a thoracic surgeon; if the patient only requires conservative treatment, they will likely be transferred to the respiratory department; if the patient's condition is critical, they might be admitted to the ICU.

Can pneumothorax be inherited?

In fact, medicine has found that most diseases, other than traumatic ones caused by injuries or car accidents, are related to genes or heredity. For instance, diseases like diabetes and hypertension clearly have a familial hereditary history. Pneumothorax is no exception, as it also tends to cluster in certain families, or has a higher tendency than in normal families. Therefore, pneumothorax does possess a certain hereditary nature, particularly in families prone to connective tissue disorders such as Marfan Syndrome. Additionally, pneumothorax often occurs in families with mutations in the human leukocyte antigen, and in those with conditions such as homocystinuria or antitrypsin deficiency, where pneumothorax is more prevalent. Of course, there are also conditions like Marfan Syndrome and Birt-Hogg-Dube (BHD) Syndrome in these families, which also tend to develop renal cysts, renal tumors, and skin fibrofolliculomas. Thus, the more frequent occurrence of pneumothorax in these families demonstrates that pneumothorax is genetically related and has a certain degree of heredity.
