Annular Pancreas Summary
HIDEInteractive Transcript
0:01
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.
