Congenital short esophageal disease is a congenital condition that causes vomiting and reflux during infant feeding, and can also lead to malnutrition as the infant cannot keep up. Therefore, it is important to detect the disease early and treat it early. What are the clinical symptoms of congenital short esophagus disease? The natural progression of congenital short esophagus varies and can be broadly divided into two categories, i.e., a part of patients with no clinical manifestations and no discomfort, which is only discovered by chance. The other part is mostly associated with symptoms of varying degrees, such as reflux, vomiting, choking gastrointestinal bleeding and whistling tract infection. Congenital short esophagus is mostly seen in infants and young children. Vomiting is sometimes normal and is due to incomplete cardia function, but if vomiting continues beyond 4 months and is frequent, it is mostly pathological. Congenital short esophageal vomiting is characterized by aggravation in the recumbent position and reduction or disappearance in the standing position. Persistent heavy vomiting causes wasting and stunting in children with inadequate fluid and caloric intake. In the case of secondary reflux esophagitis, the esophageal lining is eroded and ulcerated, and the vomitus may be bloody with black or tarry stools. Crying during feeding may be due to painful swallowing caused by reflux esophagitis. Gastroesophageal reflux often occurs because the infant cannot empty the stomach contents by gravity in the lying position during sleep, and because the pressure of the upper esophageal sphincter is reduced during sleep, and because the child does not have the ability to adjust his or her own position, it is easy to inhale into the trachea by mistake, causing cough, fever, bronchopneumonia, and segmental atelectasis. In congenital short esophagus with a large thoracic stomach, the distended thoracic stomach compresses the lungs, whistle and heart after a full meal and may show coughing, dyspnea, shortness of breath and increased pulse rate. Short esophagus with esophageal stricture has difficulty swallowing. When your child has symptoms of congenital short esophagus, it is important to take your child to the hospital for examination. Do not think that your child is small and should go back to the doctor when he/she is older. Then the examination is important, because the disease has to be diagnosed through the examination, which includes X-ray chest examination, upper gastrointestinal imaging, and esophagoscopy. You can learn more about them first. Please rest assured that the tests will not damage your child, it is the lack of treatment that will hurt your child.
