What are the clinical manifestations of congenital GI tract malformations? The GI tract includes the oral cavity, esophagus, stomach, small intestine, colon, anus, etc. The entirety of these structures are part of the GI tract. Congenital malformations occurring in these areas are all GI malformations, and different malformations can have somewhat different clinical manifestations. If obstruction occurs, vomiting and inability to eat will result, while more distal obstruction will result in abdominal distention, lack of exhaustion, and lack of bowel movement. In some severe cases, abdominal pain and even bloody stools and gastrointestinal bleeding may occur. In general, the patency of the digestive tract is affected, which can lead to abdominal distension, vomiting, or lack of bowel movement. This kind of digestive tract deformity mainly affects the child’s feeding and normal bowel movement, and even affects growth and development, which mainly includes these clinical manifestations.
