'''Annular pancreas''' is a rare condition in which the second part of the [[duodenum]] is surrounded by a ring of [[pancreas|pancreatic]] tissue continuous with the [[head of the pancreas]]. 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 ...

==Causes==
==[[Annular pancreas epidemiology and demographics|Epidemiology and Demographics]]==
It is typically associated with abnormal embryological development, however adult cases can develop. 


==Presentation==
==[[Annular pancreas risk factors|Risk Factors]]==


* The anomaly may be discovered incidentally in asymptomatic patients.
==[[Annular pancreas screening|Screening]]==
* In others, annular pancreas is associated with duodenal stenosis, postbulbar ulcerations, [[pancreatitis]], or biliary obstruction.
* Surgical resection is recommended for symptomatic cases.
* Early signs of abnormality include [[polyhydramnios]], or an excess of [[amniotic fluid]], [[low birth weight]], and feeding intolerance immediately after birth. 


==Diagnosis==
==[[Annular pancreas natural history, complications and prognosis|Natural History, Complications and Prognosis]]==


Postnatal diagnostic procedures include abdominal x-ray and ultrasound, CT scan, and upper GI and small bowel series.

==Diagnostic Findings==
 
* ERCP: An aberrant pancreatic duct communicating with the main pancreatic duct and encircling the duodenum.
* CT or MR images may show normal pancreatic tissue, with or without a small pancreatic duct, encircling the duodenum.
* Upper GI serier: Narrowing of the second portion of the duodenum.

==Case Studies==
[[Annular pancreas case study one|Case #1]]


Treatment usually is bypassing the obstructed segment of dudenum by duodeno-doudenostomy. 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>
