Abstract

Background: Annular pancreas (AP) is a congenital disorder of the pancreas, thought to result from the malrotation of the ventral pancreatic bud. This causes the duodenum to be encircled by the pancreatic tissue, leading to duodenal obstruction. The management of annular pancreas is usually surgical. Clinical Description: A 10-month-old male infant presented with regurgitation of yellowish feeds for the past few months, with no other positive clinical findings. Radiological investigations revealed an obstruction after the first part of the duodenum. A barium swallow showed duodenal stenosis. The patient underwent surgery, and the diagnosis of annular pancreas was confirmed. Management and Outcome: After clinical and radiological diagnosis, the child was managed surgically and underwent duodenojejunostomy. Postoperatively, the patient remained clinically stable and is symptom-free. Conclusion: Annular pancreas is a rare but significant cause of duodenal obstruction, which can present from the neonatal period to adulthood. The patient may experience bilious or non-bilious vomiting. The definitive diagnosis is made via laparotomy. Surgical management is required, with duodenojejunostomy being the best treatment option.
