This portion of the pancreas can constrict the duodenum and block or impair the flow of food to the rest of the [[intestine]]s. It occurs in 1 out of 12,000 to 15,000 newborns.<ref name="pmid16254852">{{cite journal |author=Lainakis N, Antypas S, Panagidis A, ''et al'' |title=Annular pancreas in two consecutive siblings: an extremely rare case |journal=European journal of pediatric surgery : official journal of Austrian Association of Pediatric Surgery ...

Another approach is [[laparoscopic]] [[gastrojejunostomy]].<ref name="pmid16494188">{{cite journal |author=De Ugarte DA, Dutson EP, Hiyama DT |title=Annular pancreas in the adult: management with laparoscopic gastrojejunostomy |journal=The American surgeon |volume=72 |issue=1 |pages=71–3 |year=2006 |pmid=16494188 |doi=}}</ref> ==References== <references/> [[Category:Diseases]] {{disease-stub}} {{Congenital malformations and deformations of digestive system}} [[pl:Trzustka obrączkowata]]
