She recovered well through minimally invasive thoracoscopic surgical treatment, with organs returned to their place and diaphragmatic breaks repaired intact. Diaphragmatic hernia caused by congenital developmental malformation has a high recurrence rate in the late stage, parents should pay attention to the daily care of the child, regular review and strengthen the monitoring of the condition. Basic information] Female, 2 years old [Type of disease] Congenital diaphragmatic hernia [Hospital] The First Affiliated Hospital of Kunming Medical University [Date of consultation] February 2021 [Treatment plan] Intravenous medication (glucose-sodium chloride injection) + gastrointestinal decompression + oxygen absorption + surgical treatment (thoracoscopic repair of diaphragmatic hernia) [Treatment cycle] Hospitalization for 7 days, follow-up 1 month [Treatment effect] The child’s organs were returned to their place, and the diaphragm was completely repaired. The damaged diaphragm was completely repaired, and there was no abnormality in the follow-up. The child, female, 2 years old, came to our hospital because of persistent cough with intermittent wheezing, and was observed to have difficulty in inhaling, which was a mild form of dyspnea. The parents said that the child had been crying a lot recently and had constipation symptoms, sometimes not having a bowel movement for 1-2 days in a row, and the feces discharged was more smelly than before, and the child had vomited after eating for the last 3 days, and after vomiting, he cried and said he was not feeling well, and could not speak after crying, and he kept falling down and gasping for breath. According to the parents’ description, the child was given a systematic imaging examination, which revealed a diaphragmatic hernia. Since no acquired triggers were found during the history taking process, the child was admitted to the hospital for treatment of a congenital diaphragmatic hernia. After magnetic resonance examination, it was found that the child’s left lung was located in the upper part of the left thoracic cavity, the mediastinal heart was obviously shifted to the right thoracic cavity by compression, and the heart was located in the right thoracic cavity; there was no obvious sign of fluid accumulation in the abdominal cavity, and the liver, spleen, and both kidneys were visible, with basically normal positions and sizes, and the bladder was well-filled. The treatment of the child focused on improving pulmonary function and reducing vascular resistance preoperatively, prolonging the time of preoperative preparation, and performing surgical treatment after improving the internal environment and maintaining hemodynamic stability. After adequate preoperative preparation and active implementation of warmth, oxygenation, blood oxygen monitoring, glucose sodium chloride injection to correct the disturbance of water electrolyte and acid-base balance, as well as gastrointestinal decompression, oxygen and other measures, after the clinical symptoms are relieved, respiratory and hemodynamic stabilization, the child will be treated with thoracoscopic diaphragmatic hernia repair. (MRI: the left lung was located in the upper part of the left thoracic cavity, and the mediastinal heart was obviously shifted to the right thoracic cavity by compression) (MRI: the heart was located in the right thoracic cavity, and there were no obvious signs of fluid accumulation in the abdominal cavity. (MRI: the heart was located in the right thoracic cavity, and there was no obvious fluid accumulation in the abdominal cavity. The liver, spleen and kidneys were visible, and their positions and sizes were basically normal, and the bladder was well filled). After the operation, the child’s respiration returned to normal, vomiting, shortness of breath, abnormal defecation and other symptoms disappeared, and the child was discharged from the hospital after 7 days of treatment. The child was discharged after 7 days of hospitalization. At the 1-month follow-up, the child’s condition had recovered well and there were no abnormal symptoms, but further observation was still needed. The child’s condition has improved and he was treated in time. However, the parents of the child are advised to review the patient on time after discharge from the hospital, and if constipation, vomiting or any other chest or abdominal discomfort recurs during the follow-up period, the child should be seen immediately to avoid delay in diagnosis and treatment. In daily life, children should be given easy-to-digest, high-protein, fiber-rich foods, such as chicken, fish, milk, soybeans, eggs, etc., avoiding high-fat, high-sucrose, high-salt diets, drinking plenty of water, eating more fresh fruits and vegetables, and replenishing vitamins and micronutrients. Parents need to pay attention to the child’s diet control and weight control in the process of growth, to avoid the child’s obesity and other factors that increase the probability of disease recurrence. V. Personal perception Congenital diaphragmatic hernia is a congenital malformation, constipation, vomiting, dyspnea is a common symptom, if it can be detected at an early stage, it can be treated with thoracolaparoscopic surgery. As the child in this article, diaphragmatic hernia is caused by congenital developmental malformation, the probability of recurrence in the later stage is relatively high, parents need to pay attention to the daily care of the child, regular review, strengthen the monitoring of the condition, to prevent recurrence of the disease.
