What genetic defect is duodenal atresia associated with?

Down Syndrome

2

What exposure is associated to hypertrophic pyloric stenosis?

Macrolides

3

What is derived from ventral pancreatic bud?

Uncinate process
Main pancreatic duct

4

What is derived from dorsal pancreatic bud?

Body
Tail
Isthmus
Accessory pancreatic duct

5

What is it called when the vetnral and dorsal buds of the pancreas fail to fuse?

Pancreas divisum

6

Falciform Ligagment

- Liver --> anterior abdominal wall
- Ligamentum teres hepatis (derivative of fetal umbilical vein)

7

Hepatoduodenal Ligament

- Liver --> duodenum
- Portal triad: proper hepatic a, portal v, common bile duct

8

Pringle Maneuver

Compress hepatoduodenal ligament during surgery to control bleeding

9

Gastrohepatic Ligament

- Liver --> lesser curvature of the stomach
- Gastric a
- May be cut during surgery to access lesser sac

10

Gastrocolic Ligament

- Greater curvature and transverse colon
- Gastroepiploic arteries
- Part of GO

11

Gastrosplenic Ligament

Greater curvature and spleen
- Short gastrics, L gastroepiploic
- Part of GO

12

Splenorenal Ligament

Spleen --> posterior abdominal wall
- Splenic artery and vein, tail of pancreas

13

Where are Brunner glands found and what do they secrete?

HCO3-

14

Where are Peyer Patches found?

Ileum

15

Where does celiac trunk come off aorta?

T12/L1

16

Where does SMA come off aorta?

L1

17

Where does IMA come off aorta?

L3

18

Where does aorta bifurcate into left and right common iliac?

L4

19

SMA Syndrome?

- Intermittent intestinal obstruciton sx (postprandial pain) when 3rd portion of duodenum (transverse) is compressed between SMA and aorta
- Diminished fat (low body weight, malnutrition)

20

Above pectinate line - A, V, L, N

A: IMA (superior rectal artery)
V: IMV (superior rectal vein)
L: internal iliac lymph nodes
N: visceral
- Internal hemorrhoids not painful

21

Below pectinate line - A, V, L, N

A: inferior rectal artery (from internal pudendal)
V: inferior rectal v --> internal pudendal v --> internal iliac --> common iliac --> IVC
L: superficial inguinal nodes
N: inferior rectal branch of pudendal (somatic)
- External hemorrhoids (painful if thrombosed), anal fissures, SCC

22

Femoral Sheath Contents

- Femoral vein, artery, and canal (deep inguinal LN) but NOT femoral nerve
- Lateral to medial: nerve, artery, vein, lymphatics

23

What structures do indirect inguinal hernias go through?
- Male infants

Internal (deep) inguinal ring, external (superficial) inguinal ring, into scorum
- Covered by all three layers of spermatic fascia

24

Indirect inguinal hernia relationship to inferior epigastric vessels?

- LATERAL to inferior epigastric vessels

25

What is the cause of indirect inguinal hernia?

Failure of processus vaginalis to close (can form hydrocele)

26

What structures do direct inguinal hernias go through?
- Old men

Inguinal (Hesselbach) triangle directly through abdominal wall
- Goes through external (superficial) inguinal ring only
- Covered by external spermatic fascia

27

Direct inguinal hernia relationship to inferior epigastric vessels?

MEDIAL to inferior epigastric vessels

28

What structures do femoral hernias go through?
- Females

- Femoral canal --> protrudes below inguinal ligament

29

Femoral hernia relationship to pubic tubercle?

BELOW and LATERl to pubic tubercle

30

Borders of inguinal (Hesselbach) triangle?

Inferior epigastric vessels, lateral border of rectus abdominis, inguinal ligament
