Malposition of the Major Duodenal Papilla and Polysplenia

Major duodenal papilla and its normal anatomy.

The major duodenal papilla (papilla of Vater) is the point where the dilated junction of the bile and pancreatic ducts (ampulla of Vater) enter the duodenum. The ampulla is surrounded by the sphincter of Oddi, which not only controls the flow of bile and pancreatic juice into the duodenum, but also prevents the reflux of duodenal contents, bile and pancreatic juice into the bile and pancreatic ...

Major duodenal papilla in autoimmune pancreatitis.

Autoimmune pancreatitis (AIP) is a distinctive form of chronic pancreatitis that can mimic pancreatobiliary malignancies.

In addition to elevated serum IgG4 levels, IgG4 immunostaining of involved tissue is often used to support the diagnosis of AIP. The ma...

Re: heterotopic pancreatitis with obstruction of the major duodenal papilla.
