On the eve of the May Day holiday, Mr. and Mrs. Yang, who live in Yongcheng, Henan Province, happily received their beloved son, who was born just 70 days ago, from the doctors of the pediatric surgery department of the downtown hospital and wept with joy. The baby boy with congenital diaphragmatic hernia (a pseudonym) was finally discharged from the hospital after careful treatment by the pediatric surgery team of Zhou Xuewu. He was diagnosed with a left thoracoabdominal hiatal hernia and was hospitalized in several local and Xuzhou hospitals, but never underwent surgery. On April 16, he came to our hospital at 10:00 a.m., and was admitted to our hospital by the deputy director of pediatric surgery, Dr. Zhou Xuewu, who was born 70 days ago. After repeated and careful examination and analysis, Dr. Zhou found that the child’s left diaphragm was mostly missing, the stomach, intestines and spleen were herniated into the left thoracic cavity, the lungs were infected on both sides, the left lung was not dilated, the heart was severely displaced to the right side, and the right lung was also squeezed, which was a rare case of “severe congenital diaphragmatic hernia”. What is congenital diaphragmatic hernia? According to Zhou Xuewu, in a normal human body, the thoracic and abdominal cavities are completely separated by the diaphragm so that the lungs can breathe normally, while a congenital diaphragmatic hernia, in layman’s terms, means that the diaphragm is born with a hole in it and organs in the abdominal cavity, such as the stomach and intestines, can run into the thoracic cavity, causing severe pressure on the heart and lungs, thus leading to severe cardiopulmonary dysfunction and high mortality if not treated urgently. Therefore, early surgical treatment is necessary for egglets. Immediately, Xuewu Zhou led his team to develop a detailed surgical plan for Egg Boy and performed an emergency diaphragmatic hernia repair at around 5:00 pm that day. The diameter of the left diaphragmatic defect was 8.0 cm, and the operation went smoothly, and the lung infection was controlled and the cyanosis disappeared after the operation.
