Q

ENV technology in the use of biliary mapping during lap chokes can be advantageous compared to use of intraoperative cholangiograms because:

A

Eliminates radiation exposure for staff, no risk of bile duct injury caused by insertion of trans cystic catheter, the average cost is $780

Q

Gallstones:

A

May develop when there is too much cholesterol in bile secreted by liver

Can get lodged in the cystic duct, accumulate in the gallbladder or get stuck in the bile ducts where they can lead to inflammation or infection

Most common gastrointestinal disorder resulting in hospitalization

Q

t/f: The strobing function can be activated from the camera head with the 1588 and L10 combo only

A

True

17
Q

What is primary reason surgeons perform intraoperative cholangiograms?

A

Identification of gallstones, especially in common bile duct

18
Q

CMOS

A

Complementary Metal-Oxide Semiconductor

Used for building circuits

19
Q

It is recommended to inject _ to__ ml of ICG for assessment of biliary system

A

0.5; 0.75

20
Q

When in spy modes, gain will adjust the intensity of the NIR signal the camera receives

A

True

21
Q

Most surgeons rely on ______ mode for perfusion assessment

A

Contrast

22
Q

Overlay does not allow for Auto Light and Over Lat simultaneously.

A

False

23
Q

The _______ light source was the first introduction of multi color LED technology

A

L9000

24
Q

Similar to 1588, the 1688 has 3 distinct laser levels to adjust

A

False

25
Q

Though it appears to get brighter, again can only be adjusted in Oveay and ENV mode since Contrast mode only adjusts the light output

A

False

26
Q

1688 ENV

A

Reduces spotlight Effect

27
Q

1688 has an improved CSF mode due to increase in pixel density

A

False

28
Q

Gain and brightness function can be applied to any buttons on the camera head in SPY mode

A

False

29
Q

Why should I worry about perfusion in my bowel resection?

A

Besides technical aspects, adequate view perfusion is the main factor in ensuring integrity of an anastomosis
