The gastrointestinal tract develops from the endoderm during the third week of gestation. By the fourth week, the foregut, midgut, and hindgut have formed and will contribute to different parts of the GI system. Notable milestones in GI development include the formation of the stomach, esophagus, liver and pancreas by 5-7 weeks and intestinal lengthening by 8-12 weeks. Tracheo-esophageal fistula and esophageal atresia are birth defects where the esophagus fails to form properly, sometimes connecting abnormally to the trachea. They require surgical correction, often in stages, to allow for feeding and prevent aspiration. Close nursing observation and care is needed
