1

What are medical colics?

can be resolvecd with medical treatment
"simple" colic
inflammatory conditions

2

What can be causes of abdominal pain?

1. distension (fluid, gas, ingesta--obstruct)
2. pulling on root of mesentery
3. ischemia or infarction--strangulation
4. deep ulcers in stomach or intestine (right dorsal colitis)
5. peritoneal pain (peritonitis)

3

Do obstructed horses have ischemia/infarction?

no, thus are often less systemically sick, no risk of reperfusion industry

4

What is the name of distension in stomach? in cecum, which are most common (distention)

stomach--dilation
cecum--tympany
stomach and cecum most common

5

What are the most common causes of colic in field?

spasm--gas colic

6

What are the categories of disease (medical)

1. obstruction
2. distension
3. spasm
4. ulceration
5. inflammation (enteritis, colitis, peritonitis)

7

Where do spams occur?

small intestine or large intestine

8

What are important features of spasms?

no obstruction, no loss of perfusion

9

Where are ulcers most common

in stomach and right dorsal colon

10

What are causes of medical colic in teh stomach

1. gastroduodenal ulceration
2. distension
3. obstruction

11

What are causes of medical colic in the small intestine

duodenitis-proximal jejunitis
ileus
spasm

12

What are causes of medical colic in the large intestine?

gas accumulation (tympany)
impaction
colitis

13

What are causes of medical colic in the peritoneum

peritonitis

14

What are non-GI causes of "colic"

mesenteric abscess
ovarian tumor, abscess, hematoma
parturition
uterine artery rupture
liver disease
ruptured bladder (foal)
urinary tract, renal dz
pleural dz
laminitis

15

What are causes of esophageal obstruction?

primary obstructions--in esophagus
secondary impactions--other masses

16

What factors predispose to primary impactions?

simple choke
prior trauma
dental abnormalities
wolfing of food
diverticulum

17

What is a big concern with choke?

the esophageal if damaged it tends to heal with strictures! or with diverticula--risk of recurrent chocke

18

What are causes of secondary impactions?

foreign bodies
masses
acquired or congenital anomalies

19

How is esophageal obstruction treated?

gentle lavage, endoscopy

20

what is the biggest complication of choke?

aspiration pneumonia

21

What can happen is esophageal obstruction not recognized in time?

esophageal rupture, causes swelling of the neck area

22

What are signs of esophageal choke?

anxious
neck extended
gag, retch
forthy nasal discharge bilateral
look this up

23

gastric ulcers in foals are caused by what?

poor perfusion of stomach

24

What are risk factors for gastric ulcers?

1. stress
2. transportation
3. high grain diet
4. stall confinement
5. intermittent feeding
6. intense exercise
7. racing
8. illness
9. management changes
10. NSAID use

25

What are clinical signs of gastric ulcers?

1. acute colic
2. recurring colic
3. excessive recumbency
4. poor BCS
5. partial anorexia
6. poor performance
7. attitude changes
8. frequent stretching to urinate
9. chronic diarrhea

26

Where are the two big locations for gastric ulcers?

squamous mucosa
pyloric region (NSAID)

27

What causes pain with stomach distention?

the distention of the stomach

28

What happens to the angle of the cardia with stomach distention?

the cardia angle gets more closed off. If have trouble getting into the stomach with NG tube, then consider that there is an issue with the stomach--severely gas distended or impacted e.g.

29

Why would you tube a horse with a high heart rate/colic early on?

in case of stomach distension--tube to relieve and prevent rupture and if the heart rate decreases, then indicates the heart rate was high due to pain

30

Is ileus usually a primary or secondary problem?

secondary
