Dear Vickie,
fluid accumulating in the legs, called edema, can be the result of malnutrition, liver disease, heart failure, kidney disease, and/or a bunch of other things. here is a nice web site to learn more about edema:

http://www.healthatoz.com/healthatoz/Atoz/ency/edema.jsp Using compression stockings puts pressure on the legs and returns some of the fluid to the circulation. If a person is unable to handle the extra fluid, such as a patient with heart failure, the extra fluid can tip them into congestive heart failure, landing them in the hospital and possibly killing them.
If the cause of the edema is malnutrition due to the pancreatic cancer, I wonder if anything can be done to improve her nutritional status, such as ppn, tpn, or perhaps a feeding tube. not only would that help the edema, but improved nutrition may give her some more time.

Tell the oncologist everyone is concerned about the edema and it interferes with walking; tell him/her you are wondering if the edema is due to malnutrition, show him/her the web pages. Ask the oncologist what was the Albumin level (a measure of malnutrition) on the bloodwork done during her last doctor's visit. The normal range for albumin for most labs is 3.4 to 5.4 g/dL. If it is below 3.4 she is malnourished.
Edema is an annoying problem. Correcting it, in your mother's case, may be tough.
Practical matters about compression stockings (my own opinions): Most people wind up not wearing their compression stockings because they feel so tight (if they are not tight, they are not going to do any good). Before buying a pair or two, clear it with her doctor. They come in different strengths of compression and they come in different lengths (knee high won't work, they will squeeze the fluid from the feet into the thighs, don't get knee high ones). The best thing to do is to get her doctor to write out exactly what compression stockings (strength, length) he wants, and how many pairs (2 pair is good) on a prescription pad. Insurance may pay for them depending on the insurance (at least they used to). Don't attempt to put them on in the afternoon. Put them on before she gets out of bed first thing in the morning or after a quick washup in the morning. The longer she is standing up in the morning, the more edema there will be (gravity pulls the fluid into the lowest parts of the body so that is why the legs are affected more than the arms). If she stands up too long there will be too much fluid in the legs to get the compression stockings on. Having two pairs, one for the dirty laundry, and one to wear, is a good idea.
Compression stockings are not the same as support stockings. Compression stockings have a compression level of 20mmHg or higher. Compression stockings are used for things like prevention of blood clots after surgery or for serious edema in patients who do not have heart failure. Support stockings are for relief of tired legs, mild swelling, spider veins, etc. Here is a web site that talks about the care of the stockings:

Best wishes for both you and your mom. She is lucky to have such a caring daughter.
