Patient: Hello, Director Xiao. The child was born 28 days ago and has been spitting up milk for 10 days. He was examined at the hospital and told that it was normal and he would get better with careful care, but gradually the spitting up became more and more serious. The child has not eaten well for almost half a month and has lost more than one pound. The child is too young, and I am worried that the lack of food for such a long time will cause malnutrition and affect growth and development. Xiao Dong: You can come to the hospital to see me, if the pneumonia is not serious, we can arrange for surgery as soon as possible. Patient: Thank you, Mr. Xiao, I will go to your clinic today, thank you very much! Xiao Dong: Currently, I perform minimally invasive surgery to treat hypertrophic pyloric stenosis. Once the diagnosis is confirmed, surgery is needed as soon as possible.
