The Value of Ultrasound in Diagnosing Fetal Congenital Digestive Tract Abnormalities and Abdominal Wall Defects

Objective To evaluate the value of ultrasound in diagnosing congenital digestive tract abnormalities and abdominal wall defects.Methods The OB ultrasound examinations of 136 cases with digestive tract abnormalities and 41 cases of abdominal wall defects were analyzed , those cases came from Alta Bates Perinatal Diagnostic center , Oakland, California USA during 5 years recently.Results In 136 cases of digestive tract abnormalities, 9 cases were esophageal atresia, 19 cases were duodenal atresia, 12 cases were jejunal atresia, 68 cases were echogenic bowel, 19 cases were meconium peritonitis, 9 cases were diaphragmatic hernia. In 41 cases of abdominal wall defects, 11 cases were gastroschisis, 18 cases were omphalocele, 12 cases were amniotic band syndrome. Each type had its special image feature,which is correlated to errors in embryonic developments. Conclusion Many digestive tract abnormalities and abdominal wall defects can be readily detected and diagnosed by ultrasound . Ultrasound is valuable in diagnosing fetal congenital digestive tract abnormalities and abdominal wall defects.
