when does polypectomy needed a cancer operation

A

Invading submucosa - haggitt level 4

Sessile

Lymphovascular invasion

Poorly differentiated

18
Q

management of small adenoma

A

repeat scope in 3 years

19
Q

Screening options for colon cancer

A

age 50

I. felx sig q 5 yrs and yearly FOBT

II. Double contrast barium enema q 5 yrs

positive contrast: barium or barium-like agent, e.g. Gastrograffin ®
negative contrast: air or CO2

C scope q 10

20
Q

Lynch syndrome

What is the treatment

A

If found to have colorectal cancer

Total abdominal colectomy with ileorectal anastomosis

and

With post op ANNUAL
endoscopic surveillance of the remaining rectum

Females after children
get TAH BSOO

(40 – 60% chance of endometrial cancer)

21
Q

If there is any previous colon resection what is needed for further procedure

A

Total colectomy

22
Q

What is the Niagara protocol

A

5-FU because everyone gets this

Mitomycin-c

mity mouse will see if chemo works

5-FU

Mitomycin C

45 gy (uptodate)

23
Q

Treatment of carcinoid in the appendix at the base known preoperatively what medication should you prepare the patient with set timer for 15 minutes

A

If known cancer:
Give octreotide preoperatively

Right hemicolectomy

24
Q

What extra colonic cancer do patients get with FAP

And what is the treatment

A

Periampullary adenocarcinoma

Whipple

25
Q

FOLFOX

A

Fu L Ox

Fluorouracil
Leucovorin
Oxaliplatin

26
Q

Management of carcinoma in a polyp

A

can be effectively managed by endoscopic removal (polypectomy) alone as long as the resection margins are free of cancer for:

severe dysplasia
or
carcinoma in situ (no evidence of invasive cancer),

The presence of any of the following factors should prompt consideration of radical surgery:

●Poorly-differentiated histology

●Lymphovascular invasion

●Cancer at the resection or stalk margin

●Invasion into the muscularis propria of the bowel wall (T2 lesion)

●Invasive carcinoma arising in a sessile (flat) polyp with unfavorable features (eg, lower third submucosal penetration, lymphovascular invasion, poorly differentiated)

27
Q

If the patient is seen with a painful thrombosis within 24 to 48 hours, the treatment of choice is

A

immediate excision of the hemorrhoid

(not evacuation of the clot) under local anesthesia.

The patient who presents later:
treated with Sitz baths; 
stool softeners; 
topical anesthetics, 
astringents, 
 steroids 

to aid in rapid resolution of symptoms
since natural reabsorption of the clot has started

28
Q

If an outside provider has done the scope to diagnose calling cancer what needs to be done for preoperative arrangements

A

Tattoo colon cancer sight

Consider Re-scope to get distance measurements.

29
Q

After Acute appy with IR drain draining feculent material

A

DDX:

Drain may have been put through the bowel

This may be a fistula from Cecal stump leak

Tx:
TPN
