Annular pancreas in neonate patients Vomiting and weight loss in a 13-day newborn

Abstract

Objective: Reinforce that, despite being a rare condition, the annular pancreas must be considered a differential diagnosis for intestinal obstructions in the newborn period. Case description: This case report refers to a 13-days newborn admitted to the emergency room presenting with postprandial vomiting and progressive weight loss since maternity discharge. The patient did not respond to initial interventions that included IV antibiotics and nasogastric tube insertion. A contrast study of the upper digestive tract (esophagus, stomach, and duodenum) found a luminal narrowing on the second duodenal portion. The patient was submitted to an exploratory laparotomy which found a pancreatic-tissue ring involving the second part of the duodenum. Despite rare, we reinforce that the annular pancreas must be considered a differential diagnosis for intestinal obstructions in the newborn period. Comments: Annular pancreas is a rare congenital defect in which a ring of pancreatic tissue encircles the duodenum, causing different degrees of intestinal obstruction.
