What kind of tissue is pancreatic tissue?

glandular

not smooth

no outside lining to help us see it

1

Where is the pancreas found intra or retroperitoneum?

Retroperitoneum

2

What are the landmarks around the pancreas?

retroperitoneum

anterior pararenal space

posterior to the lesser sac

3

What is the technical challenge of US pancreas?

ileus-dilate loops of bowel without peristalsis (blockage of bowel)

4

What organ is the anterior boundry of the panc?

stomach

posterior: Ao and IVC

5

What lies in the anterior pararenal space?

the pancreas

6

What is the typical measurement of the panc?

12cm x 2cm

7

What are the four sections of the panc?

head, neck, body, and tail

8

What kind of position does the panc lie?

horizontal-oblique line

from the concavity of the duodenum to the hilum of the spleen

9

Where does the head of the panc lie?

anterior to the ivc and left renal vein

inferior to the caudate lobe and portal vein

finish slide 9

10

What artery is above the panc?

the celiac trunk (superior)

find seagull sign and angle down to see panc

11

What structure does the superior mesenteric vein cross?

crosses anterior to the uncinate process of the head of the gland and posterior to the neck and body of the pancreas

12

What is the uncinate process?

the small, curved tip at the end of the head of the pancres

lies anterior to the inferior vena cava and posterior to the superior mesenteric vein

13

What passes through a groove posterior to the pancreatic head and the gastroduodenal artery?

the common bile duct

14

What vessel lives in the pancreatic notch?

SMV

notch - space between head and uncinate process

15

What is found directly anterior to the portal-splenic confluence or SMV?

the neck of the panc

16

What is formed posterior to the neck by the junction of the SMV and SV?

The portal vein

17

What part of the panc is the largest part?

the body

lies posterior to the stomach and anterior to the origin of the portal vein

18

What part of the panc rests anteriorly to the Ao , the origin of the SMA the Left renal vessels, left adrenal glands and left kidney?

The body of the pancreas

19

What is the superior border of the panc body?

the tortuous

splenic artery

20

What courses the posteromedial surface of the pancreas to join the main portal vein?

the splenic vein

21

Where does the tail of the pancreas lie?

anterior to the left kidney, close to the spleen and left colic flexure

22

The splenic vein forms the _________ border, and the _______ forms the superoanterior border.


posterior

stomach

23

What is Wirsung's duct?

the primary duct of the panc extending the ENTIRE length of the gland

receives tributaires from lobules at the right angles and enters the medial second part of the duodenum with the cbd at Vater's ampulla

24

What is Santorini's duct?

a secondary duct that drains the upper anterior head

it enters the duodenum at the minor papilla approx 2cm (smaller duct) at ampulla of vater.

25

What are the measurements for the panc?

Head < 2.5cm

tail < 2.0 cm

26

What is the echogenicity of the pancreas?

> liver

spleen (depends on fatty/fibrous texture)

27

What is the echotexture of the pancreas?

homogeneous

28

What is the surface of the pancreas look like...

smooth to slightly lobular (islets of langerhans)

29

Where does the panc get its blood from?

splenic artery and pancreaticoduodenal arteries

venous drainage is through tributaries of the SV and SMV
