Feeding Intolerance and Vomiting Caused by Duodenal Pancreatic Heterotopia in a Neonate

211 ABS TRACT Öz Pancreatic heterotopia (PH) is a congenital abnormality defined by the presence of an ectopic pancreatic tissue outside the usual anatomic location of the pancreas. The frequency of the disorder is reported to be 0.2-15% in autopsies, 1-2% in laparotomies. The most common locations are the stomach, duodenum and jejunum. The symptoms develop as per the localization particularly in the elderly. We presented a term neonate with a birth weight of 4460 gr hospitalized due to bilious vomiting 10 days after birth. The neonate presented 17% of dehydration, jaundice, and hypochloremic alkalosis on admission. Upper gastrointestinal contrast study demonstrated delayed passage. A mass of lace appearance in the second part of the duodenum was observed by endoscopy and was surgically excised. The diagnosis of PH was made through histopathological analysis. We want to highlight that although relatively rare, PH should be considered in the differential diagnosis of neonates with vomiting and feeding intolerance. The mass must be excised, if the symptoms develop.
