A three-week old male infant is brought to the office by his father because of non-bilious vomiting that is small in quantity but frequent. He has gained 8 ounces since birth and has been a fussy baby who does not like to feed. Abdominal imaging shows tissue surrounding the second portion of the duodenum. Which of the following developmental mechanisms best describes the etiology of this condition?
Failure of pancreatic ventral bud rotation. This patient’s nonbilious vomiting and poor weight gain in the neonatal period combined with his abdominal imaging results suggests the presence of annular pancreas. Annular pancreas is a congenital abnormality with a prevalence estimated at 5 to 15 per 100,000.
During normal development, the pancreas develops from dorsal and ventral buds. The former becomes the tail and body, while the latter become the head and uncinate process. The ventral bud first passes behind the duodenum during rotation of the gut and then fuses with the dorsal bud. Failure of this rotation with the duodenum causes entrapment of the duodenum, which is believed to be the pathogenesis of annular pancreas.
Approximately ⅔ of patients are asymptomatic. Clinical manifestations depend on the severity of duodenal obstruction. These range from abdominal discomfort, postprandial fullness, and nausea to pancreatitis.
