Flashcards in L09: Abdominal Exploratory: Small Animal Sx (Johnson) Deck (18):
1

advantages of laparotomy

-can do full thickness intestinal biopsies
-biopsy/excision of SP, LIV, Pancreas, KID, prostate
-ability to address/obtain hemostasis
-option for therapeutic intervention if indicated and can directly visualize (ie. splenectomy, liver lobectomy, intestinal resection/anastomosis, enterotomy)

2

disadv. of laparotomy

-inc. morbidity
-pain
-anesthetic risk
-cost
-dehiscence
-infection

3

diagnostic indications for laparotomy

-PLE (from IBD, lymphoma, etc.)
-Hepatopathy (form microvascular dysplasia, copper storage, etc.)
-suspected neoplasia (from mass effect)

4

therapeutic indications for laparotomy

Rads: free gas, dilated SI, FB, herniation, or GDV
Abdominocentesis:
-Blood: active clots
-Urine: inc. creatinine or K
-Cytology: intracellular bacteria (sepsis), bilirubin (GB rupture)

5

if abdominal bleeding due to splenic mass, will it clot?

NO

6

loss of cranial mesenteric artery -->

loss of 90% of blood supply to intestines

7

slip test with stomach**

serosa submucosa slides away and left holding serosa muscularis

8

L gutter

retroperitoneal space with colon and mesocolon retracted

9
