Congenital diaphragmatic hernia is a condition in which the fetal diaphragm fails to close completely during development and is left as a fissure in the diaphragm, with herniation of abdominal tissue into the thoracic cavity. Clinical symptoms depend on the volume of abdominal organs herniated into the thorax, the degree of organ dysfunction and the degree of respiratory and circulatory dysfunction caused by increased intrathoracic pressure. Some children also have gastrointestinal symptoms, with a turbid or tympanic sound on percussion of the affected side of the chest, decreased or absent breath sounds, and occasional bowel sounds on auscultation, and intestinal gas shadows on radiography of the affected side of the chest. After a clear diagnosis, congenital diaphragmatic hernia requires early surgical treatment, which is divided into two routes: transthoracic and transabdominal. Thoracoscopic transthoracic surgery can be more minimally invasive, with smaller postoperative scars and faster recovery, while the postoperative effect is no less than that of traditional open surgery. We have achieved satisfactory results and are well received by families and colleagues. Most of the congenital diaphragmatic hernia cases have obvious signs of hypoxia after birth, and some of them need ventilator, so the first impression of the family is that the condition is critical and some of them choose to give up the treatment, but from our postoperative survival rate, it can reach 95% and the respiratory condition can be improved, only some children need oxygen for a longer period of time, and the recurrence rate is 5%.
