Intestine Flashcards
When do we give prophylactic antibiotics?
Clean contaminated / contaminated surgery
20 min before incision
every 90-100 min intra-op
(at most only 24hrs post-op)
Cefazolin 22mg/kg
What suture pattern(s) should we use in the intestine?
- *appositional** (for primary healing)
- simple interrupted or simple continuous
- Modified Gambee (helps w/everted mucosa)
*submucosa is holding layer!*
Monofilament absorbable / stapling devices
How do we perform intestinal biopsy?
full-thickness, wide enough that all layers remain intact
3-4 mm wide
*transverse wedge technique should not be >20-25% of circumference*
What location is an obstruction more likely to be if the patient presents with more acute, severe signs (persistent vomiting, dehydration) ?
duodenum or proximal jejunum
What location is an obstruction more likely to be if the patient presents with more chronic, lethargic, vague signs?
more distal:
distal jejunum, ileum, ileocecal junction
Where do we begin anastomosis?
mesenteric border
What type of diet is best for medically managing Megacolon Cats?
low residue diets
Surgical management (unsuccessful medical management) for megacolon ?
colectomy:
-jejunocolic anastomosis (tension-free closure)
-ileocolic
-colocolonic (more tension- so sometimes we’ll remove the ileocecal valve)
ileocecal valve preservation:
-increases tension at anastomosis
-avoids bacT overgrowth
-no real clinical benefit
When would we perform serosal patching?
When omentum is not available…
reinforcement of suture lines in questionable tissue:
enterotomy
colotomy
urinary bladder
Closure management for colotomy?
longitudinal, single layer
simple interrupted, appositional
What would the indicated surgical treatment be if a patient is having recurring episodes of rectal prolapse?
colopexy
