Q

Peritonitis

A

inflammation of peritoneum (due to organ inflam, surgery, trauma, etc)
parietal layer is innervated by somatic nerves—>well localized somatic pain
visceral layer is innervated by autonomics (stretch and chemical irritation fibers)

Q

inferior recess of the lesser sac

A

b/w the two layers of the greater omentum

17
Q

greater sac

A

cavity that lies anterior to the stomach divided by the transverse colon into the supracolic and infracolic compartments

18
Q

supracolic compartment contents

A

superior to transverse mesocolon

contains the stomach, liver, spleen, GB

19
Q

infracolic compartment contents

A

inferior to the transverse mesocolon
contains the small intestine, ascending colon, descending colon
divided into L and R by the mesentery proper

20
Q

boundaries of the epiploic foramen

A

anterior: hepatoduodenal ligament
posterior: IVC
superior: liver
inferior: first part of duodenum

21
Q

Ascites

A

exs fluid in the peritoneal cavity (cirrhosis and portal HTN, kidney failure, CHF, ulcer, internal bleeding)

fluid tends to pool in the hepatorenal and subphrenic recesses

22
Q

Celiac trunk level

A

TV12

23
Q

superior mesenteric a. level

A

L1

24
Q

Inferior mesenteric a. level

A

L3

25
Q

Foregut

A

liver, GB, stomach, esophagus, pancreas, spleen

blood from Celiac Trunk (T12)

26
Q

Midgut

A

3rd part of duodenum, distal 2/3 of transverse colon

from superior mesenteric a. (LV1)

27
Q

Hindgut

A

distal 1/3rd of transverse colon to anorectal junction

blood from the inferior mesenteric a. (LV3)

28
Q

Esophageal Varices

A

dilated veins the the esophagus caused portal HTN

occurs due to anastomoses b/w esophageal v. (to SVC) and L gastric v.

29
Q

Caput medusa

A

dilated abdominal veins due to portal HTN

occurs due to anastomoses b/w superior and inferior epigastric v. (to SVC and IVC) and paraumbilical v.

30
Q

Hemorrhoids

A

dilated veins in the rectum

occurs due to middle and inf rectal veins (to IVC) and superior rectal veins

31
Q

Retroperitoneal dilated veins

A

occurs due to anastamoses b/w gonadal and renal veins ( to IVC) with iliocolic, R , middle, and L colic veins
