2. Left oblique

3. Paramedian

4. Ventral midline

5. Venrrolateral

6. Right paracostal

3

What major structures can be accessed from the left side in a celiotomy?

Rumen, gravid uterus

4

What major structures can be accessed from the right side in a celiotomy?

Abomasum, SI, LI (cecum, spiral colon), gravid uterus

5

What procedures can be done from the left side?

  1. Exploratory celiotomy
  2. Rumenotomy/ostomy
  3. LDA
  4. C-section

6

What procedures can be done from the right side?

  1. Exploratory celiotomy
  2. Abomasal disorders
  3. C-section

7

What steps are taken to prepare the animal for a paralumbar fossa celiotomy?

Clip, aseptically prepare, local anesthesia, drape

8

Where do you want the incision to be in the PL fossa?

In the center of the fossa - can adjust for target organ

9

What layers are you incising through at the level of the PL fossa?

  1. Skin
  2. SQ
  3. External abdominal oblique mm
  4. Internal abdominal oblique mm
  5. Transversus abdominis
  6. Peritoneum

10

How many layers are you going to close in the PL fossa?

3-4

11

What suture material and pattern do you use to close the deep layers of the PL fossa? What direction do you go?

Absorbable, simple continuous

Ventral to dorsal

12

What suture material and pattern do you use to close the skin of the PL fossa? Which direction do you go? How far from the ventral aspect do you end your closure?

Non-absorbable, ford interlocking/simple continuous, interrupted ventral

Dorsal to ventral

End closure 3-5 cm from ventral aspect

13

What structures can be accessed from a ventral midline approach?

  1. Abomasum
  2. Reticulum
  3. SI
  4. LI
  5. Urinary bladder
  6. Uterus

14

What procedures can be done from a ventral midline approach?

  1. Exploratory celiotomy
  2. Displaced abomasum
  3. Herniorrhaphy
  4. Omphalectomy/omphalophlebectomy
  5. C-section
  6. Tube cystotomy

15

What layers are you incising thru in a ventral midline approach?

Skin, SQ, linea alba, rectus abdominis, peritoneum

16

How many layers are included in your closure at ventral midline?

3-4

17

What layers of the body wall do you close in a ventral midline approach? What suture material and pattern do you use?

Linea alba, rectus abdominis

Absorbable, simple continuous

18

What suture material and pattern do you use to close the skin on a ventral midline approach?

Non-absorbable, absorbable

Ford interlocking, simple continuous

19

What organs are accessed with a right paracostal celiotomy?

Abomasum, SI, LI

20

What procedures can be done from a right paracostal approach?

Exploratory celiotomy, abomasal disorders

21

Where, anatomically, is the right paracostal incision made?

Parallel and caudal to the last rib

22

What layers are you incising thru with a right paracostal approach?

  1. Skin
  2. SQ
  3. External abdominal oblique mm
  4. Internal abdominal oblique mm
  5. Transversus abdominis
  6. Peritoneum

23

How many layers are closed in a right paracostal approach?

3-4

24

What layers are closed in the deep closure? What suture material and pattern do you use?

Transversus abdominis, peritoneum;

Absorbable, simple continuous

25

What is the middle layer that is closed in a right paracostal approach? What suture material and pattern do you use?

Abdominal oblique muscles;

Absorbable, simple continuous

26

What suture material and pattern do you use to close the skin on a paracostal approach?

Non-absorbable, absorbable;

Ford interlocking, simple continuous

27

Which of Halsted's principles are important in food animal GI surgery?

  1. Gentle handling of tissue
  2. Preservation of blood supply
  3. Strict aseptic technique
  4. Minimize tension on tissues

28

What two things do you want to avoid in FA GI surgery? Why?

Handling gentle tissues with fingertips, dry gauze;

Abrades the serosa and promotes adhesion formation

29

How can we best preserve blood supply?

Use anatomical and sharp dissection

30

How can we practice strict aseptic technique?

1. Isolate GIT (lap sponges, gravity)

2. Split table (dirty = enterotomy, clean = laparotomy closure)

3. Copious lavage

4. Change barriers
