Abstract
A case of a 0-day-old girl. Bile was vomited immediately after birth. Small intestinal atresia was suspected after X-ray examination. It was confirmed by ultrasonography after hospitalization. The girl was diagnosed to have small intestinal atresia by intrauterine intussusception. Since we understood the situation of intestinal atresia before the operation, the operation was completed by upper abdomen midline incision. Ultrasonography is useful for intestinal atresia. There is no report of diagnosed intestinal atresia by intrauterine intussusception in reference to a newborn.
