Q

Which of the following is incorrect about the lower digestine tract (small and large intestines)?

a. SI contains microbes, proteins, undigested fibers, sugars, and also material that was not absorbed by the abomasum.
b. It is the longest section of GIT, where most things are digested and absorbed.
c. Duodenum is the first section that mixes chyme and digestive fluids from GB and pancreas.
d. Jejunum is a short coiled middle section where chyme breakdown takes place.
e. Ileum is the site of Vit b absorption, also bile salts and products not absorbed by jejunum.

A

d. Jejunum is a short coiled middle section where chyme breakdown takes place.

Jejunum is a LONG coild middle section

sorry for the dick moves….still more to come.

Q

T/F: Obstructive dz of the small intestine is very common and occurs regularly enough to cause major problems economically.

A

SUPER FALSE.

Not common as forestomach and abomasal disorders.

Happens enough that we can learn from them.

22
Q

What are some causes of obstructive dx of the small intestine?

A

These causes are seldomly obvious:

volvulus

torsion

intussusception (more in calves)

obstruction

Hemorrhagic bowel syndrome

23
Q

Which of the following is not correct about obstructive dz of small intestine?

A

e. metabolic acidosis in duodenum

metabolic alkalosis in duodenum

A

False

Increased hydration, attitude, heart rate

25
Q

When does intussusception occur?

colic in first 12-24 hours then will se anorexia, no manure, deH, and abdominal distention

Hx

CS

rectal palp

US

dairy

low

fermentable feedstuffs

hypocalcemia

endotoxemia

indigestion

34
Q

What is the pathway for cecumand colon dilation and volvulus?

A

Cecum dilation

severe dilation

cecum apex migrates to pelvic inlet

further distension

leads to rotation and torsion (clockwise)

35

Reduced manure production

a. mild/moderate colic with rumen fx affected
b. hypocalcemia with intestinal motility reduced
c. Water retention due to twisted cecum/colon
d. Serum chloride

A

c. Water retention due to twisted cecum/colon

deH

Serum chloride not huge changes like with DA

37
Q

HOw do you dx cecum and colonic dilation and volvulus?

Cs

ASCULTATION AND BALLOTTMENT

Ping right flank (dorsal caudal more evident) X DDx = RDA

Serum chloride

MUST RECTALLY PALPATE TO ID CECUM

38
Q

Which of the following is not an appropriate form of tx for cecum and colonic dilation and volvulus?

d. Sx anastamose the affected area, usually has good prognosis
e. A and B
f. C and D

A

f. C and D

Its all backwards.

Sx for little to no manure production

why would i anastamose anything, it was a bad idea before and its a bad idea now

39
Q

Which of the following is incorrect about colonic obstructions?

Abd distension

tachycardia

no manure

anal sphincter and rectum are NORMAL

Normal appearence

They are drinking colostrum

42
Q

You are a farmer and you suspect your calf may have atresia coli. What you looking for in the first 24-73h of life?

A

going off feed

abdominal distension

deH

+/- colic

Deteriorate (SEVERELY SICK by 5-7 days old)

43
Q

How do you dx atresia coli?

A

US

IgG because even with colostrum can see low to no absoprtion. 50% chance + outcome.

44
Q

How do you sx tx atresia coli?

A

surgically bypass the anastamose

Anatomic confusion

Relative large diameter section of proximal colon to the small diameter descending colon.

45
Q

Which of the following is incorrect about atresia ani?

a. Occurs more often in piglets than cattle
b. Cs are seen right after birth
c. Rectal pull through technique is not a recommended form of tx
d. One of the main CS is not seeing them pass manure and seeing a rectal lumen bulges SQ where anus should be.

A

c. Rectal pull through technique is not a recommended form of tx

Freaking do this! way better outcome!!!

46
Q

Which of the following is incorret about Pneumoperitoneum?

a. The free gas stuck in the peritoneal cavity is released once cut through peritoneum during celiotomy
b. Occurs after exploratory laparotomy
c. Rectal palpation is fairly easy
d. Abomasal perforation is more often related to pneumoperitoneum.

A

c. Rectal palpation is fairly easy

Rectal palp is difficult.

DX: PE, rectal palp, DDX of other dz by causing ping (especially if its bilateral in a situation like this)

47
Q

How would you treat Pneumoperitoneum?

A

Nothing if mild case

Suction via needle in the right flank (be careful)

Fis perforated organ if possible

Abx +/-

48
Q

c. Can be dx at necropsy as a cause of death
d. Can be dz with PE, rectal palp, US

A

a. INfectino of peritnoeum has terrible absoprtion so you have to be careful

Has excellent absorption

49
Q

How can you treat peritonitis?

A

Heavy Abx therapy broad specturm, PPG high []

flunixin meglumine

Supportive therapy (fluids IV and oral)

Try to solve the cause of the leak/contamination
