Answer 2

Mayhew, JAVMA, 2014:

1. A 3cm access incision centered midway between the caudal margin of the xiphoid cartilage and the umbilicus provided access for minimally invasive abdominal organ biopsy for most organs, although access to all hepatic lobes and all parts of the pancreas was inconsistent
2. 17% conversion rate

Question 3

Fransson, Vet Surg, 2015:

Benefit(s) of lift laparoscopy over capnoperitoneum laparoscopy?

Answer 3

Fransson, Vet Surg, 2015:

Lift laparoscopy was associated with less frequency of hypercapnia and required less anesthetic gas, but was not more time-consuming or painful than capnoperitoneum laparoscopy

Question 4

Elliott and Kirberger, Vet Surg, 2015:

1. Best patient positioning for access to the ipsilateral kidney, ovary and uterine horn?
2. Best patient positioning for access to the bladder and uterine body?

Answer 4

Elliott and Kirberger, Vet Surg, 2015:

1. The best patient positioning for access to the ipsilateral kidney, ovary and uterine horn is the opposite lateral position to the side being approached
2. The ventrodorsal Trendelenburg was best for accessing the bladder and uterine body

Question 5

Kennedy, Vet Surg, 2015:
Lift laparoscopy

Effect of increasing lift tensions?

Answer 5

Kennedy, Vet Surg, 2015:

Increasing lift tensions increased working distances, except to caudal abdominal structures

Question 6

Steffey, Vet Surg, 2015:
Extirpation of medial iliac lymph nodes

1. The lateral approach allows dissection of the ipsilateral medial iliac lymph node but precludes removal of the contralateral lymph node - true or false?
2. What % of dogs had mild to moderate hemorrhage?
3. What % of dogs had tearing of the capsule of the lymph node?
4. What % of lymph nodes had minor peripheral pinch artefact and what % had minor central pinch artefact affecting a median of 5% of the surface area of the lymph node?
5. On the left-sided approach, which vessel is more laterally positioned?
6. On the right-sided approach, which vessel is more laterally positioned?

Answer 6

Steffey, Vet Surg, 2015:

1. True
2. 50% had mild to moderate hemorrhage
3. 38% had tearing of the capsule of the lymph node
4. 100% had minor peripheral pinch artefact and 44% had minor central pinch artefact affecting a median of 5% of the surface area of the lymph node
5. On the left-sided approach, the external iliac artery is more laterally positioned than the external iliac vein
6. On the right-sided approach, the external iliac vein is more laterally positioned than the external iliac artery

Question 7

Gonzalez-Gasch and Monnet, Vet Surg, 2015:
Single port access vs multiple port access systems

1. Duration of surgery for single port access vs multiple port access system procedures?
2. What % of cases had splenic puncture using the single port access vs multiple port access systems?
3. Intra-op complication rates for single port access vs multiple port access systems?
4. Conversion rate to open surgery for single port access vs multiple port access systems?

Answer 7

Gonzalez-Gasch and Monnet, Vet Surg, 2015:

1. Duration of surgery for single port access system procedures was significantly reduced compared to corresponding multiple port access system procedures
2. Splenic puncture occurred in 0% of the single port access system procedures vs 17% of the multiple port access system procedures
3. Intra-op complication rates: 0% for single port access system vs 22% for multiple port access system
4. Conversion rate to open surgery: 0% for single port access system vs 6% for multiple port access system

Question 8

Jeong, Vet Surg, 2016:
Retroperitoneal laparoscopy

Effect(s) of increasing pressures from 5mmHg up to 10mmHg?

Answer 8

Jeong, Vet Surg, 2016:

As pressures increased, working space was established from the ipsilateral to contralateral side, and peritoneal tearing eventually developed

Question 9

Petrovsky and Monnet, Vet Surg, 2018:
Repeated decontamination and sterilization of single-incision laparoscopic surgery ports

Bacteriologic cultures results from ports used 4 times vs ports used 8 times?

Answer 9

Petrovsky and Monnet, Vet Surg, 2018:

None of the ports that were used 4 times had positive bacteriologic cultures, but 33% of the ports used 8 times had a light growth of Staph epidermidis and other Staph spp, and Micrococcus spp were cultured from the foam components

Question 10

Leschnik, Vet Surg, 2018:

Veress needle penetration depth was the least at which location?

Answer 10

Leschnik, Vet Surg, 2018:

Veress needle penetration depth was the least at the 9th intercostal space compared to the preumbilical, paraumbilical and subumbilical sites

Question 11

Anderson and Fransson, Vet Surg, 2019:
Complications related to entry techniques

1. Minor complication rate?
2. Major complication rate?
3. Which entry location was 12 times more likely to be associated with complications?
4. Odds of complications using the modified Hasson needle entry vs Veress needle entry vs Ternamian visual entry?

Answer 11

Anderson and Fransson, Vet Surg, 2019:

1. Minor complication rate: 19%
2. Major complication rate: 2%
3. A paramedian entry was 12 times more likely to be associated with complications than a midline entry
4. Odds of complications was 5 times more likely after the modified Hasson needle entry and 28 times higher after the Veress needle entry compared to the Ternamian visual entry

1. Mesenteric lymphangiography was successful via the wound retractor device in 79% of the clinical cases and 100% of the cadavers?
2. Cisterna chyli ablation was successfully performed in 100% of the clinical cases?
3. 21% of dogs developed severe chyloabdomen post-op
