The success rate after surgery for congenital megacolon is considered to be relatively high. The success rate of congenital megacolon surgery is higher than 90%, but it needs to be treated as early as possible. If the treatment is not timely and the best time for treatment is missed, the success rate of surgery will be greatly reduced. Congenital megacolon is most easily detected in infancy and childhood, with clinical manifestations such as constipation, abdominal bulging, indigestion, and decreased diet. Patients with mild symptoms can choose minimally invasive surgery with little harm. After surgery, proper care is needed. Diet should be less intake of high-fat food, liquid diet, more coarse grains and fresh vegetables, fruits, etc. Drink more water to promote intestinal peristalsis, keep the stools smooth and reduce constipation. Avoid alcohol intake, pay attention to vitamin supplementation, actively participate in sports, such as jogging, etc., to enhance their own resistance. Pay attention to the prevention of infection, avoid intestinal adhesion.
