So let's review.

0:02

Some procedural and Perry procedural considerations in image guided

0:05

biopsies of intra-abdominal lesions.

0:08

So it's very important for us to understand the indications as

0:11

well as the contraindications of any thing. We

0:14

do particularly biopsies.

0:16

So let's discuss indications.

0:18

So when it comes to introdominal biopsies, it's important

0:21

to know one of the reasons why we could perform

0:24

this procedure is to differentiate a suspected

0:27

primary tumor from a probable peritoneal spread

0:30

in the case of peritoneal carcinomatosis. We

0:33

want to understand whether or not the primary

0:36

tumor is actually migrated and has

0:39

become stage 4 disease.

0:41

Secondly if there's a societies that's of

0:44

a known origin in the setting of a specialist lesion because that

0:47

and of itself would also suggest that the patient has now stage

0:50

4 disease if there's a primary cancer and

0:53

we're uncertain what the staging

0:56

of this particular cancer is a biopsy would be

0:59

appropriate in the setting as well.

1:01

If there's concomitant malignancy.

1:03

This is in settings where a diagnosis may actually

1:06

alter the treatment regimen, of course, there's surgery which

1:09

is very different than surgery and chemotherapy which

1:12

is very different than chemotherapy by itself. And so

1:15

being able to understand exactly what we're doing and

1:18

what we're offering to the patient data-driven management is

1:21

really what we want to use these biopsies

1:24

for when it comes to infiltrative lesions and potential

1:27

initiation that has a history of TB or

1:30

sorekaidosis.

1:32

This is also another indication for this sort of

1:35

tissue sampling.

1:37

So when it comes to interabdominal biopsychondrainications, of

1:40

course we are well aware that if we're biopsying

1:43

a patient we want to be mindful of the hematologic parameters.

1:46

Is there a risk for bleeding INR is

1:49

greater than 1.5 or two PT is

1:52

greater than 15 seconds of normal ptts

1:55

greater than 40 seconds platelets count

1:58

less than 50,000 would be

2:01

things that would sort of give us pause before we move forward

2:04

with performing a biopsy.

2:07

And in some certain situations these parameters could

2:10

be corrected. And so we're going to be mindful of them as we

2:13

proceed.
