Currently the best and most accepted is thoracoscopic minimally invasive funnel chest correction. The minimally invasive thoracoscopic technique for the treatment of funnel chest involves making 2-3 (≈1.5 cm) small holes in the chest wall without cutting the sternum and ribs. The procedure is indicated for patients with funnel chests ranging in age from 3 to 50 years old, as well as for patients who have failed to be treated with conventional surgery. The reduced incision size greatly reduces the incidence of complications – less trauma; compared to traditional surgical treatments for funnel chest (such as sternal reversal), which open the chest, the use of only about a 2 cm “incision” in the chest wall reduces the surgical damage during the procedure. The overall recovery time is greatly reduced for the patient – faster recovery; open chest surgery means that a large incision is made in the chest wall, directly touching the entire chest cavity as the scope of surgery. The thoracoscopic surgery method is to make only 3 “holes” in the chest wall with the help of TV camera technology and miniature lumpectomy instruments, and the “3 holes” contrast with the “centipede type” scars on the chest wall –More aesthetically pleasing. The thoracoscopic treatment of funnel chest also fully reflects its “minimally invasive” characteristics: the premise of ensuring the surgical effect, minimizing the surgical trauma, reducing the postoperative pain, shortening the postoperative recovery time, low cost of surgery, bleeding only about 10-30ml, no blood transfusion, etc. Limitations in age: Traditional surgery is very harmful to the patient due to the surgery itself, and being too old or too young in terms of physical recovery and tolerance will increase the risk of the surgery. In contrast, thoracoscopic minimally invasive orthopaedic surgery of funnel chest is our safe and effective choice in the treatment of funnel chest in all age groups. Endoscopic observation makes it safer to establish posterior sternal access and the efficacy is excellent. We believe that although the procedure is straightforward and bleeding is low, some important technical details of the procedure determine the success or failure of the procedure and the postoperative outcome, and it is very important that the surgeon is aware of the limitations of the procedure. All surgeries are also extremely demanding for the surgeon, and then the choice of surgeon becomes a key factor. The Department of Thoracic Surgery of Shanghai Long March Hospital has completed many cases of minimally invasive thoracoscopic treatment of funnel chest, and because of the advanced thoracoscopic technology, our Department of Thoracic Surgery has become a technical training base for thoracic surgeons in Shanghai. Preventive care for funnel chest Funnel chest is a congenital and often familial disease. It is more common in males than females, with a reported male to female ratio of 4:1, and is a dominant trait. The main manifestation is that the sternum in the front and middle part of the child’s chest leads the surrounding connected ribs to collapse inward into a funnel shape, which causes the organs in the chest cavity to be compressed and even displaced, and leads to a serious impact on the development and function of the child’s heart and lungs. The disease is familially dominant and there are no effective preventive measures. In children with less severe thoracic deformities, preventive measures should be taken to prevent their progression. In the 1970s, the age of the youngest patient for this type of surgery abroad was about 4 to 5 years. At present, the optimal age for surgery should depend on hospital conditions and the level of the surgeon. Experts believe that the best time to correct a funnel chest is between the ages of 2 and 4 years old, according to the characteristics of pediatric bone quality, and that surgery at a younger age may not affect the development of the child. At present, most of the results of such surgeries in children aged 1 to 3 years are very good. Health care tips: 1, guide the child to eat a high protein, high calorie, high vitamin diet, such as meat, eggs, milk, fresh fruits and vegetables. 2, if necessary, intravenous fluids, supplement energy, vitamins, application of antibiotics and hemostatic drugs. 3, the diet is supplemented with foods high in calcium, such as shrimp, kelp, sesame paste, etc., and pay attention to the amount of exercise and vitamin D supplementation at the same time. 4, the child the day after surgery, fasting, water, no abdominal distension, nausea and vomiting symptoms the next day after surgery can eat, generally first eat liquid, semi-liquid diet, and gradually transition to a normal diet. 5, because the postoperative bed time is long, should pay attention to eat fiber-rich vegetables, bananas, etc., to prevent constipation. 6.Avoid strenuous sports for one year after surgery.
