The success rate of megacolon surgery is generally over 90%, which is a very high success rate, but early treatment is needed, and the success rate of surgery will be greatly reduced if treatment is not timely. Giant colon is usually congenital and is easily detected in infancy, mainly manifesting as abdominal bulging, constipation and indigestion. After surgery, the child needs to be taken care of, given a liquid diet, and avoid crying. It is also important to prevent infection after surgery, especially after intestinal surgery, which can be complicated by intestinal adhesions.
