Colopexy

Colotomy (AVOID)

4

What is a clean wound?

Nontraumatic, noninflamed operative wounds;

Respiratory, GI, urogenital, and oropharyngeal tracts are not entered

5

What is a clean-contaminated wound?

Respiratory, GI, or urogenital tracts are entered under controlled conditions without unusual contamination;

Clean procedure in which a drain is placed

6

What is a contaminated wound?

Traumatic wounds without purulent discharge;

Spillage of GI contents or spillage of infected urine occurs;

Major break in aseptic technique occurs

7

What is a dirty wound?

Traumatic wounds with purulent discharge, devitalized tissues, or foreign bodies;

Perforated viscus or fecal contamination occurs

3.5-4.5%

10

What is the infection rate of a contaminated wound?

4.6-9.1%

11

What is the infection rate of a dirty wound?

6.7-17.8%

12

What is the approach/steps to accessing the abdominal cavity?

  1. Ventral midline (xyphoid to pubis)
  2. Skin incision
  3. Remove SQ tissue from linea
  4. Grab linea with forceps, lift, inverted blade for stab incision
  5. Feel for adhesions
  6. Extend with mayo scissors

13

What grip of the scalpel handle provides for more stability?

overhand

14

What is the advantage to incising on the linea alba?

Less bleeding - better for the patient and for visualization

15

When should an abdominal exploratory be done?

Every time you enter an abdomen

16

What are the general steps to a gastrotomy and when would you do one?

Do for foreign body:

1. Isolate areas of interest from remainder of abdomen

2. Stay sutures can help

3. make full-thickness incision

How many layers does closure of the stomach involve and what are they?

2 = mucosal-submucosa, seromuscular

18

What suture pattern and material should be used for stomach closure?

Inverted (Cushing), interrupted/continuous

Absorbable, monofilament, tapered needle

19

What is the most common correction for GDV?

Derotate and do an incisional gastropexy

20

What are the steps to an incisional gastropexy?

1. Feel mucosal slip

2. Incise only seromuscular layer

3. Incise body wall (transversus abdominis) caudal to last rib

4. Suture together with simple continuous pattern, absorbable material (PDS)

Adenocarcinoma (42-72%);

Pylorus and lesser curvature

22

What are possible gastric neoplasias in dogs other than adenocarcinoma?

Lymphoma, leiomyoma

What suture material and pattern should be used in an enterotomy?

Absorbable suture, appositional pattern (gambee)

29

What color is concerning in the intestines?

Black and purple

30

How can we measure intestinal viability?

Color, blood supply, feel (thin/friable?), peristalsis
