The physician on call is paged to the well-baby nursery because a full-term, 3-hour-old boy has had green emesis twice, once after each of his feedings. He is being breast-fed. He was born by spontaneous vaginal delivery following a pregnancy complicated by polyhydramnios. His Apgar scores were 8 and 9 at 1 and 5 minutes, respectively. His temperature is 37°C (98.6°F), blood pressure is 70/50 mm Hg, pulse is 150/min, and respiratory rate is 24/ min. His upper abdomen is distended, soft, and without palpable masses. Air is visualized in the duodenum and the stomach on x-ray. Which of the following is the most likely diagnosis?
(A) Duodenal atresia
(B) Hirschsprung’s disease
(C) Intussusception
(D) Malrotation with volvulus
(E) Pyloric stenosis
