Due to recurrent vomiting and reluctance to feed, a 3-day-old child is taken to the emergency room by her parents. Vomiting started early in the morning and has been greenish-yellow in hue. There is no blood in the emesis. The baby appeared to be dehydrated. Her heart rate is 175 beats per minute, and her blood pressure is normal. Following the completion of the first assessment, the infant will have a laparotomy. A normal-looking duodenum, the lack of a substantial section of jejunum and ileum, and the remains of the distal ileum looping around a slender vascular stalk are among the findings. Which of the following intrauterine processes is most likely to be at the root of this patient's condition?
