So the next important anomaly is annular pancreas.

0:05

And that is basically the presence of the

0:07

pancreatic tissue around the duodenum.

0:09

It forms a ring together.

0:11

And that can be seen in infants, mostly

0:13

presenting with trisomy 21,

0:16

duodenal atresia, or tracheoesophageal fistula.

0:18

And that may be symptomatic or may cause

0:21

obstruction as soon as the baby is born.

0:24

In an adult patient, if the patient reaches

0:26

to that age group, it will lead to peptic

0:28

ulcer disease or pancreatitis and cause pain.

0:30

0:31

And this is how this happens.

0:33

As we discussed earlier, there are two different

0:34

buds, ventral and dorsal bud, and they

0:37

rotate together, but during the rotation it is

0:39

possible that the ventral bud actually leaves

0:41

a circular tissue along with the duodenum,

0:45

and that is retained there and doesn't absorb.

0:48

And during this migration, or rotation,

0:51

the duct is actually there inside, so that is

0:53

very diagnostic because we can see that

0:55

duct encircling the pancreas along with

0:58

the duodenal lumen that is encircling ring

1:00

around with that and that is very diagnostic.
