Recently, a child with critical thoracic trauma was discharged from our hospital after undergoing thoracoscopic surgery. The advanced minimally invasive technology and strong emergency treatment capability once again won the heartfelt thanks of the patient’s family. A 4-year-old child was playing in front of his home when he was involved in a car accident, suffering from severe chest trauma and dying. The family quickly consulted the local hospital, and the CT examination of the chest showed “multiple rib fractures on the left side, massive hemopneumothorax, and severe lung contusion”. The local hospital had limited technology, so the doctor recommended transferring the child to our hospital for treatment. After the child was admitted to our hospital, the critical condition of the child was on the mind of every medical and nursing staff. The director led the team to conduct a thorough analysis of the child’s condition and finally decided to perform emergency pediatric thoracoscopic surgery. With the careful cooperation of the operating room of the anesthesiology department, the child lay on the operating table and a 5mm thoracoscope entered the child’s chest cavity. After removing a large amount of hemothorax, a severe contusion of the left lower lung was found and was immediately repaired with absorbable sutures. The procedure went smoothly, took a short time and was minimally traumatic. With the collaboration of the medical and nursing teams from the Department of Critical Care Medicine and the Department of Thoracic Surgery, the child survived the surgery and recovered quickly. TV thoracoscopic surgery has long been a mature technique in our thoracic and cardiovascular surgery department, reaching the advanced level in China, and has become the preferred surgical method in thoracic and cardiovascular surgery. Pediatric thoracoscopic techniques are extremely demanding in terms of operator skills, anesthesia management, perioperative care, and lumpectomy instruments. The small size of the pediatric thoracic cavity, the small operating space, and the delicate lung tissue require gentle, quick, and accurate operation to avoid excessive pulling and clamping of the lung tissue and to reduce the incidence of postoperative complications such as pulmonary edema. Our pediatric thoracoscopic technology is at the forefront in China, and we have successfully completed more than 100 cases of pediatric TV thoracoscopic surgery, 30 of which were infants and children less than 3 years old. It mainly involves the treatment of more than 10 complex diseases including ligation of unclosed arterial ducts, acute and chronic abscess chest, spontaneous pneumothorax, pleural effusion, mediastinal tumor removal, etc. Our Thoracic and Cardiovascular Surgery Department created the National Health and Family Planning Commission Training Base for Endoscopic and Minimally Invasive Techniques earlier in China. “To teach someone to fish is not as good as teaching someone to fish”. Advanced technical training will certainly promote the development of minimally invasive thoracic surgery for the benefit of patients.
