Annular pancreas is a rare congenital anomaly characterized by the presence of ectopic pancreatic tissue surrounding the duodenum. This manifestation results from failure of ventral pancreatic bud during normal migration during development [Duodenal ulcer in 1st part of duodenum, duodenal stenosis in between 1st and 2nd part of duodenum]. This malformation is usually asymptomatic in adults, but can manifests as pancreatitis, duodenal stenosis, or obstruction or duodenal or gastric ulceration. We report the case of a young patient of 25 years old hospitalized for epigastric pain and vomiting for 5 years, in whom radiological investigations showed an annular pancreas. At operation a complete obstruction of the duodenum between its 1st and 2nd parts was found, caused by an annular pancreas. No other congenital anomaly of the intraabdominal organs was noted. A TV & gastro-enterostomy (G-J) was performed. Both the rarity of this congenital abnormality and its successful correction by surgical means has promoted us to make the following presentation.
