Stomach and small intestine

• Upper abdominal swelling may or may not be present
• Early vomiting of large amounts, which may be greenish (containing bile)
• Continued vomiting even when infant has not been fed for several hours
• Absent urination after first few voidings
• Absent bowel movements after first few meconium stools

• This condition may be suggested by fetal ultrasound showing polyhydramnios (excessive amounts of amniotic fluid in the uterus) or swelling of the stomach and part of the duodenum
• A plain abdominal x-ray may show air in the stomach and first part of duodenum, with no air beyond that
• An abdominal x-ray with contrast may be helpful
