Congenital megacolon is a serious disease, whose main symptoms are constipation and vomiting. Because of the lesion in one section of the intestinal canal, there are no ganglion cells and it is in a spastic state, which causes the stool and gas not to be easily expelled, the child is prone to abdominal distension, vomiting and even intestinal obstruction. In severe cases, it may even cause intestinal perforation and diffuse peritonitis, and the child’s general condition will also be affected, easily showing symptoms such as wasting, anemia, decreased resistance and easy infection. So congenital megacolon must be treated in time, the earlier the treatment, the better the results. Congenital megacolon is not untreatable, and generally speaking the majority of children need timely surgery to treat it. If you don’t treat it in time, for example, when the child is older, nearly ten or even more than ten years old, the effect of surgery will be greatly reduced.
