Laparoscopy

Question 1

Laparoscopy

Answer 1

Procedure done with a laparoscope to look inside of the abdomen with a tiny camera

Question 2

What are 3 pros and cons of a laparoscopy?

Answer 2

Pros: rapid return to function, relatively noninvasive, quick to perform
Cons: expense of equipment, skill of surgeon, video image is 2D (depth perception off)

Question 3

T/F: You can use a laparoscopy procedure to assess an acute colic case?

Answer 3

FALSE- only used for chronic cases

Question 4

What is the most common indication to perform a laparoscopy?

Answer 4

Cryptorchidectomy

Question 5

What biopsy procedures use the laparoscopy procedure?

Answer 5

Liver, spleen and kidney

Question 6

What type of needle is used for an abdominal tap?

Answer 6

Verres needle

Question 7

What is used to treat pneumoperitoneum?

Answer 7

CO2- adding gas will cause the negative pressure to go away so all organs fall ventrally

Question 8

Where are four cavities created when a patient has a pneumoperitoneum?

Answer 8

Right body wall and cecum
Cecum and mesentery
Left body wall and spleen
Spleen and mesentery

Question 9

What are the landmarks for a standing laparoscopy?

Answer 9

Tuber coxae
Internal abdominal oblique muscle
18th rib

Question 10

What should be used when performing a recumbent laparoscopy?

Answer 10

IPPV- abdominal organs will inhibit the diaphragm from moving up and down

Question 11

What type of ligature is sued when performing a laparoscopy?

Answer 11

Roeder knot

Question 12

What are three common post-op complications of a laparoscopy?

Answer 12

Post-op discomfort (CO2 mixes with abdominal fluid leading to carbonic acid formation, use banamine to take care of this)
Hemorrhage(caudal epigastric a/v)
Local incision infection

Question 13

What are the dimensions of a laparoscope used for an adult horse?

Answer 13

Longer than 50 cm
30 degree angle
10 mm diameter

Question 14

What is the most commonly accepted gas for abdominal insufflation?

Answer 14

Carbondioxide

Question 15

What is the main disadvantage for using CO2 intra-op?

Answer 15

Turns to carbonic acid formation that can lead to irritation and peritonitis (post-op discomfort)

Question 16

T/F: The abdomen should be maximally insufflated to avoid penetrating viscera with the laparoscopic trochar-canula?

Answer 16

FALSE- want it under 20 mmHg so that cardiopulmonary function is affected

Question 17

What is the technique used for performing a laparoscopy for OHE via ventral abdominal approach?

Answer 17

1.5 cm skin incision at umbilicus for insertion of laparoscopic trochar-canula

Question 18

Why is it advantageous for an experienced surgeon to perform minimally invasive surgeries?

Answer 18

Enhanced illumination and magnification

Question 19

What is the best light source used in minimally invasive surgery?

Answer 19

Xenon

Question 20

What should the intraabdominal pressure be maintained at in order to avoid overinflation? (mmHg)

Answer 20

15

Question 21

What is not a common complication associated with laparoscopy?

Answer 21

Extensive adhesion formation

Question 22

What are the effects of laparoscopy on the cardiopulmonary function of an anesthetized patient?

Answer 22

Increased intrapulmonary shunting

Question 23

In order to avoid cardiovascular compromise, gas pressure in the thorax should be maintained below how many mmHg?

Answer 23

8
