Q

Duodenum

A

Superior - L1, starts at hepatoduodenal ligament
Descending - L1-L3, bile & pancreatic duct enter
Horizontal - L3, passes over IVC, aorta: under SMA
Ascending - L3-L2, supported by suspensory ligament of duodenum (Ligament of Treitz)

17
Q

1ST part of duodenum

A

Superior
Hepatoduodenal ligament
Intraperitoneal

18
Q

2ND part of dudoenum

A

Descending
Common bile and pancreatic ducts empty in major, lower papilla
Retroperitoneal

19
Q

3RD part of dudoenum

A

Horizontal
In front of IVC & aorta, behind SM vessels
Retroperiotoneal

20
Q

4TH part of duodenum

A

Suspensory ligament/Ligament of Treitz

21
Q

Duodenum arterial supply

A

Supplied 1/2 by celiac, 1/2 by SMA
Anastamosis at superior and inferior pancreatoduodenal a.

22
Q

Peptic ulcers

A

Lesion of mucosa
Can treat with antibiotics or vagotomy
Posteriorly could affect stomach bed organs

23
Q

Paraduodenal hernias

A

Retroperitoneal portions protrude intraperitoneally
Be careful of IMV and ascending l. colic a

24
Q

Jejunum

A

Mostly at LUQ, starts of Ligamentum of Treitz

25
Q

Ileum

A

RLQ
Communicates with LI at ileocecal junction

26
Q

Jejunum vs ileum

A

Jejenum has less large arterial arches
Jejunm has more tightly packed plicae circularis

27
Q

Large intenstines

A

Tenaie coli - muscle bands
Haustra - sacs
Omental appendages

28

A

Retroperitoneal
Top 2/3 = visceral
Bottom 1/3 = somatic
Ampulla stores feces
