MANDOJANA, Facundo I. et al. Duodenal obstructon due to anular pancreas. Rev. argent. cir. [online]. 2017, vol.109, n.4, pp.1-10. ISSN 2250-639X.

Annular pancreas (AP) is a rare congenital anomaly, characterized by ectopic pancreatic tissue surroun-ding the duodenum, that may associate with duodenal obstructon. We present a patent complaining of 12 days of abdominal pain and vomitis. Blood testis showed hyper-lipasemia. Computed tomography scan demonstrated stomach and frst duodenal porton distended in relaton to a 5 cm diameter image resembling a ring between the pancreatic head and the second porton of the duodenum, a well known characteristic of AP. Following a lack of clinical response to medical treatment, surgery was performed confirming a duodenal obstructon due to AP. Roux-en-Y gastrojejunostomy was done, with good postoperative outicome. Annular pancreas may present as a duodenal obstructon. For these cases, we suggest surgical treatment to confirm diagnosis and resolve the obstructon in cases with negative clinical response to conservative treatment.
