Funnel chest (pectus excavatum)
Pectus excavatum should go to which department?
Regarding the registration of patients or children with pectus excavatum, if it is for children and the consultation is only about the hereditary aspect of pectus excavatum or its etiology, consider registering at the pediatrics or child health department. It is also feasible to consult the genetics department. If the consultation is about treatment options for pectus excavatum, including methods of treatment, consider registering at the thoracic surgery department. Thoracic surgery can provide advice and methods for the treatment of pectus excavatum, including both surgical and non-surgical options. Of course, not all hospitals have a thoracic surgery department; generally, municipal third-level, first-class hospitals are equipped with thoracic surgery departments. If there is no thoracic surgery available, consider registering under the general surgery department.
Is pectus excavatum hereditary?
In current medical technology, although no genes exclusively associated with pectus excavatum have been identified, there is evidence suggesting genetic predisposition when pectus excavatum coincides with other conditions. For instance, the incidence of pectus excavatum is significantly higher in patients with congenital connective tissue disorders, such as Marfan Syndrome, and is linked to certain genes within this syndrome. Additionally, patients with congenital diaphragmatic hernia also show an increased incidence of pectus excavatum. Moreover, the condition is more prevalent in patients, or children, who have subglottic airway stenosis or congenital bronchopulmonary dysplasia. Thus, these evidences confirm that pectus excavatum, as a disease in itself, is directly or indirectly related to congenital genetic factors, indicating a certain hereditary nature.
Why can't people with funnel chest gain weight?
In clinical observations, we have found that children with pectus excavatum generally do not have as good nutrition as normal children, and are not as plump. This may be related to the deformity of the chest indentation. We know that the normal cross-section of the thorax on a CT scan is oval-shaped, with the heart and lungs located behind the sternum. In children with pectus excavatum, the sternum is compressed backward toward the spine, which deforms and even pushes the heart completely to one side. This compression of the heart limits the blood's ability to fully return to the heart, and may even prevent the valves from closing completely, leading to valve insufficiency. As a result, both cardiac and pulmonary functions are somewhat impaired. Therefore, 80% of children with pectus excavatum experience exercise intolerance, meaning they cannot run as well as normal children, which also indicates poorer physical fitness and, comparatively, a lesser appetite. Recent studies have found that children with pectus excavatum also have slightly weaker immune functions, and their digestive and absorption capabilities are not as good as those of typical children. Poor exercise capacity and digestive function ultimately lead to poorer nutrition in children with pectus excavatum, making them less plump than normal children.
Can funnel chest heal itself?
Actually, a portion of children with pectus excavatum can heal on their own, especially those who are newly born and discovered to have pectus excavatum. This is because children are curled up while in the mother's womb. In some cases, their hands and feet might be placed in front of the sternum, pressing it backward and inward, causing a deformity. However, once the mother gives birth and the child's limbs unfold, the pressure on the sternum is relieved. As the chest grows, it gradually returns to its normal shape, and these children with pectus excavatum can be cured. On the other hand, another group of patients do not have pectus excavatum at birth, but develop a noticeable chest indentation as they grow older. These patients, when they are young, can also be treated with conservative methods, such as using a vacuum bell for pectus excavatum to gradually draw the indentation outward. With its stabilizing effect, as the child grows, the deformity can be slowly corrected. Of course, there are also children who might have a more rapid skeletal development, and essentially become "set" in their ways. At this stage, they may require surgical intervention to treat the condition. In summary, a portion of pectus excavatum patients can be healed, while another portion requires active intervention and treatment.
Does pectus excavatum hurt?
The sternum of pectus excavatum caves inward and backward, directly compressing the patient's heart or lungs, causing a certain degree of chest pain. This chest pain is not caused by pectus excavatum itself, but by the compression of the heart or lungs due to pectus excavatum. Imagine a normal ribcage as an oval shape; its cross-section is also oval and is a ratio of the patient's left-right diameter, transverse diameter, and anterior-posterior diameter. In normal individuals, this ratio is less than 2.5. In pectus excavatum, since the anterior-posterior diameter is significantly reduced and the sternum is markedly pressed towards the spine, the patient's heart is entirely compressed and deformed. Therefore, the patient's coronary arteries or valves may be squeezed and deformed, resulting in about 60% of pectus excavatum patients experiencing chest pain.
Postoperative care for pectus excavatum
Pectus excavatum surgery involves implanting a metal plate in the patient's body; however, this type of metal plate cannot be welded to normal bones or muscles. It is only fixable using stainless steel wires or sutures. Therefore, postoperative care is crucial. Good post-surgical care significantly reduces the chances of the metal plate shifting. We recommend that patients lie flat on their backs for 3 to 5 days after the surgery, avoid bending, twisting their bodies, or rolling over in bed for a week. For a month, it's important for patients to keep their bodies straight and stand flush against a wall. Since the chest will be quite painful after the surgery, standing against a wall helps the patient maintain a proper posture. Otherwise, due to the pain, the patient may stoop forward, resulting in a hunched posture, which is unappealing and not good for the spine. Within two months post-surgery, the patient should avoid bending over to lift heavy objects as this can lead to uneven distribution of force that may cause the metal plate to shift. Intense physical activities should be avoided for three months. The patient should ideally rest in a supine position and avoid external injuries and contact or impact sports like basketball, soccer, or football. Generally, the metal plate should be removed 2 to 3 years after the surgery depending on the circumstances, so regular clinic visits are necessary to monitor the situation of the plate. If the patient experiences difficulty breathing or chest pain after being discharged from the hospital, they should immediately go to the nearest hospital to have their chest x-rayed to check the status of the metal plate.
Pectus excavatum should see which department?
If the patient is relatively young, under 14 years old, and wishes to consult about pectus excavatum care, pediatric healthcare can be considered. However, if the patient is older, or in addition to pediatric healthcare advice, seeks information on how to treat pectus excavatum, it is advisable to consult with a local thoracic surgery department, if available. This is because thoracic surgeons offer not only information on the causes or care of pectus excavatum but also treatment options. Both conservative treatment plans and surgical interventions are available from thoracic surgeons. Of course, not all hospitals have a department of thoracic surgery, but general top-tier hospitals typically do; if there is no thoracic surgery available locally, considering general surgery might be the only alternative.
Is the funnel chest suction cup effective?
If the patient is young and the chest wall still retains some elasticity, or there is a possibility of secondary development, then it might be worth trying a pectus excavatum suction cup. If during the development of the chest wall, the patient's family can actively encourage or supervise the use of the suction cup for over two hours a day, continuing for six months, preferably up to about two years, the suction cup can be somewhat effective. However, if the patient's chest wall is hard and lacks elasticity, or if there is little possibility of further development, then the suction cup might not be suitable for such patients. For patients whose chest wall has fully developed, the best or most definitive treatment for pectus excavatum is surgery. Therefore, while the pectus excavatum suction cup can be useful for some patients, it is not suitable for all patients.
Does pectus excavatum require surgery?
The decision on whether surgery is needed for pectus excavatum depends on the patient's age, the severity of the deformity, and the elasticity of the chest wall. If the patient is very young, under one year old, and the pectus excavatum is not very severe, we recommend a watchful waiting approach. In patients with pectus excavatum under one year old, it is possible that the condition is pseudopectus excavatum, which may improve as they grow and develop within the first year. However, not everyone improves, with about one third of the cases showing improvement within the first year. If the child is older than one year, the likelihood of improvement is basically none, and at this time, conservative treatment using a pectus excavatum suction cup can be considered. If adhered to effectively, the suction cup can have a certain effect for some patients with pectus excavatum. But if the patient is over three to five years old and the chest wall has matured, surgery should be considered. Therefore, for the vast majority of patients with pectus excavatum, surgery is a relatively definitive and immediately effective method.
Can people with pectus excavatum join the military?
Theoretically, the current conscription system does not have strict restrictions on mild cases of pectus excavatum. However, obvious moderate or severe pectus excavatum, or sternums that are inwardly and backwardly concave, can significantly impact the function of both the heart and lungs by compressing them. This inward concavity can restrict the heart’s ability to fully expand, potentially causing complete deformation of the heart, or even prevent the heart’s valves from closing fully, leading to valve regurgitation. Such compromised cardiac and pulmonary functions are likely unable to withstand the physical demands experienced during military service. Therefore, for moderate and severe cases of pectus excavatum, we do not recommend enlisting in the military, although the current policy does not have clear restrictions on mild cases of pectus excavatum.
