Annular pancreas producing duodenal obstruction: A case report

Abstract

<p> <span style="font-size:10.0pt;"><span style="font-family:Verdana;font-size:12px;">Annular pancreas is a rare congenital anomaly characterized by the presence of ectopic pancreatic tissue surrounding the duodenum. This malformation is usually asymptomatic in adults, but can manifests as pancreatitis, duodenal stenosis, or duodenal or gastric ulceration. We report the case of a young patient of 18 years old hospitalized for epigastric pain and vomiting, in whom radiological investigations showed an annular pancreas. At operation, a complete obstruction of the duodenum between its first and second parts was found, caused by an annular pancreas. No other congenital anomaly of the intra abdominal organs was noted. A gastroenterostomy was performed. Both the rarity of this congenital abnormality and </span><span style="font-family:Verdana;font-size:12px;">its successful correction by surgical means have promp</span><span style="font-family:Verdana;font-size:12px;">ted us to make the following presentation. </span></span> </p

Annular pancreas with duodenal obstruction- case report and review of literatures

“…The spectrum of abnormalities causing extrinsic duodenal obstruction includes annular pancreas, pre duodenal portal vein, Ladds band and volvulus 7,8,9,10 . Tiedman first described annular pancreas in 1818 and Ecker subsequently supported it in 1862 11 . The main characteristic feature is a band, or a ring of pancreatic tissue; which usually spans the descending duodenum close to ampulla of Vater resulting from the pathologically positioned embryonic part of the developing pancreas 4,12 .…”

A rare cause of a congenital duodenal obstruction in the newborn period with nonbilious vomiting: Annular pancreas

“…But this sign is not specific for AP since it can also be seen in children other conditions including duodenal atresia, intestinal malrotation, and congenital duodenal or pyloric atresia. The diagnosis of AP used to be based on duodenography which showed duedenal overextension and restriction of passage of contrast material (10). On ultrasound, the fluid-filled dilated descending duodenum may also be seen encircled by pancreatic tissue in infants (11)(12)(13)(14)(15).…”

Unexpected findings at laparotomy of a 12-year-old girl with obstructive jaundice and choledocholithiasis: a case report

“…Most of the cases are diagnosed either prenatally or in the first few days of life. 8 If the condition is neither diagnosed prenatally nor presents with complications in early life, it may be undetected until adulthood with varying complications, such as pancreatitis or gastric outlet obstruction, thereby making the diagnosis difficult. AP may coexist with other congenital anomalies.…”
