Q

PG

A

15

22
Q

Lymph nodes of the pancreas

A

Superior/inferior pancreatic lymph nodes

23
Q

Where does the pancreatic duct begin?

A

In the tail of the pancreas

24
Q

What is the region that the pancreatic duct joins the bile duct?

A

Hepatopancreatic ampulla (of Vater)

25
Q

Where does the Hepatopancreatic ampulla open into?

A

The posterio-medial wall of part 2 of the duodenum at a point called the Major duodenal papilla.

26
Q

Where does the accessory pancreatic duct empty into duodenum? and what does it drain?

A

At the minor duodenal papilla. This drains the

head and ucinate process.

27
Q

What does the lower part of the head and uncinate process drain via?

A

Via an accessory pancreatic duct

28
Q

What do papillas in pancreas contain? and function

A

Sphincteric muscle which controls the flow from the ducts

29
Q

What does the hypertrophy of the head cause?

A

Portal or bile duct obstruction (eg Gall stone blocking ampulla of Vater)

30
Q

What does the hypertrophy of the head cause?

A

Portal or bile duct obstruction (eg Gall stone blocking ampulla of Vater)

31
Q

Pancreatitis types

A

Acute (serious) (Alcoholism, bile reflux) or chronic (Calcifications, Pseudocyst)

32
Q

What is annular pancreas?

A

Ring of pancreatic tissue blocks part 2 of duodenum. New born disease (1 in 13, 000) Blocks food to GIT. Not all cases show symptoms

33
Q

What does the type of adenocarcinoma of the pancreas depend on?

A

Location

34
Q

Are adenocarincomas of the pancreas usually endocrine or exocrine?

A

90% are exocrine

35
Q

What procedure is performed for tumours in tail and head of pancreas?

A

Radical distal pancreatectomy

36
Q

What will you need after pancreatectomy?

A

Lifelong insulin and enzyme replacement.

37
Q

Why is the spleen described with the pancreas?

A

As it drains into the portal venous system.

38
Q

Where does the spleen lie? (relation to diaphragm) and quadrant/region

A

Its lies below the diaphragm in the upper left Quadrant → left hypochondrium

39
Q

What ribs is the spleen found at?

A

Found underneath the 9th, 10th and 11th ribs on the left side.

40
Q

Attachments of the spleen by ligaments x 2

A

Strong attachments to the stomach and left kidney;

  • Gastrosplenic ligament
  • Splenorenal ligament
41
Q

What is the entry and exit point for splenic vessels

A

Splenic hilum
• Splenic artery -from celiac trunk
• Splenic vein – to portal vein

42
Q

What does lymphatic drainage of the spleen occur via?

A

Via retropancreatic nodes at hilum to coeliac nodes

43
Q

Innervation of the spleen

A

Coeliac plexus by sympathetic fibres

44
Q

What does the hileum of the spleen make contact with ?

A

With the tail of the pancreas

45
Q

Splenic artery branches

A
  • Pancreatic branches
  • Short gastric arteries
  • Left gastroepiploic artery
  • Posterior gastric
46
Q

What is the anterior border notch of the spleen a relic of?

A

Of the fusion of the several lobules from which the organ arises in the embryo.

47
Q

What is the red pulp of the spleen?

A

Sinusoids and vascular sinuses filled with blood

48
Q

Function of red pulp of spleen

A

Purifies blood and removes dead or old blood cells

49
Q

Composition of red pulp of spleen x 3

A
  1. A loose connective tissue network of reticulin fibres (collagen) and stellate fibroblasts;
  2. Capillaries.
  3. Numerous sinusoids with associated macrophages
50
Q

What is the white pulp of spleen?

A

Aggregates of lymphoid tissue adjacent to central arteries

51
Q

White pulp of spleen function

A

Produces white blood cells

52
Q

x 5 clinical conditions of the spleen

A
  • Enlarged Spleen (Splenomegaly)
  • Ruptured spleen
