Judie (or anyone else who knows),

Can you please direct me to the medical studies that support this

statement. I am researching for a friend. Thanks.

Jane J: I posted references to this on the list -- If you do a search under

my screenname (ruisha@...) or even better under the subject 'pancreatic

cancer' or 'cancer', I'm sure you'll be able to find them!

The research I did online showed a strong correlation between those who had

peptic ulcer partial gastrectomies (which involved removal of the antreum

(lower stomach) and pyloric valve) and pancreatic cancer. I think there was

a 15-20 pct increased risk which lasted for quite a few years after the

surgery....

If you have problems locating these articles and sources, please tell me. I

know they are in the archives and I posted more than once about this. I know

it was about December 2000-January 2001 between the time I had my first

consult in November and my surgery in January.

This risk would not be incurred for an RNY (unless the lower stomach is

removed entirely, which I've heard can occur but it is normal to keep it in

the body) or a DS (a sleeve gastrectomy is performed which leaves the antreum

and pylorus functional and intact). It would be a consideration for the BPD

(without the DS) surgery in which the lower stomach is removed.

Just like if you do not have some sort of WLS your risks are

What the percentage of increase risk is, I have no idea. It is not

determined that all RNY patients will get this disease.

RNY patients are NOT at increased risk for this as far as I know UNLESS Their

lower stomach is removed (this is rarely the case). RNY patients can be at

higher risk for ulcers in the lower stomach and duodenum, often not showing

symptoms until the ulceration has progressed extensively b/c they do not

'use' this portion of the stomach to process food, etc.

I don't think it's the pyloric valve as much as the removal of the lower

stomach (which produces acid). Traditional BPD patients would be at risk for

pancreatic cancer (although this doesn't mean that they will get it, just

that they may be at increased risk) but not most RNY or any DS patients.

I was the one who researched this and put the info on the boards before my

surgery... Info and links are in the archives. I'm not sure, but may

also have uploaded files on this subject at a later date? So, you may want

to check the DS files, too.

Most RNY folk DO have their pyloric valve 'intact' and keep the lower part of

their stomach. It is separated from the upper 'pouch' that digests food,

however (either by stapling or being transected or cut). The lower stomach

still produces acid and this can result in ulceration of the lower

stomach/duodenum but I don't know if there's a direct link between this and

pancreatic cancer.

The studies I've seen involve removal of the lower stomach and increased risk

of pancreatic cancer as a direct result.
