27. A6-week-old male infant is brought to the physician's office because of excessive vomiting. Pregnancy and delivery were normal. The infant did well until approximately 1 week ago when he began to have occasional vomiting within 1 hour of feeding. The vomiting has increased in frequency and force over the past week, and projectile vomiting now occurs almost every time he eats. The vomitus has never been bile-stained. Which of the following is the most likely developmental basis for this abnormality? OA) Complete failure of duodenal recanalization OB) Hypertrophy of the circular musculature of the pylorus C) Incomplete recanalization of the duodenum D) Rotation of the stomach in a counterclockwise rather than clockwise direction E) Superior displacement of the stomach through the esophageal hiatus
