Prolonged fever after Plastic Stenting.Can anybody help?

My mom was diagonised OVCA in 2006 and now she is having one retropancreatic Lymph node in porta hepatis area which has externally blocked her bile duct. She developed Jaundice.
Plastic stenting was done and Jaundoce started decreasing but from 2 days after stenting she developed fever from 10th of July,09 and is going on.
In between after 6 weeks after plastic stenting her jaundice started to rise again (It came down to normal after 5 weeks) and Again she was admitted for Stent change.

It was found that plastic stent was full of White PUS cells and completely blocked. Doctor removed the pass from Bile duct and did put a Metal Stent instead.
She gopt remission from fever for 2 days and again Fever started coming in everyday. Is White PUS again blocking the stent? As earlier doctor told us that PUS is responsible for Fever.

If anyone of you have any idea what this exactly is would be a great help. We are really frustrating and my mom is gradually becoming bed ridden for her prolonged fever. And Cancer has spread to organ as of now as revealed after extensive USGs 3 times.
She has already taken 45 doses of IV antibiotics and lots of oral antibiotics.

Thank you very much. Yes we often talk to our group of doctors and you may be absolutely right. But the point is after several Ultrasonography it showed the mass is almost same in shape and size and it is an External mass pressing the bile duct so PUS can not be formed inside of the bile duct. Earlier it was assumed that normal Bacterial film which is very common for plastic stent has blocked the Stent with white PUS.
Now they are saying it is some kind of cholangitis or Acute Fungal super infection. I don't know what is going on but at the end of the day I can not tolerate the way my mom is suffering.

The pus is the leftover remnants of immune cells that are trying to fight some form of inflection that is going on. The pus is very much like 'whiteheads' that develop within the head of a pimple when there is an ongoing inflammatory reaction at some site on the tissues. In your mother's case, the infection or inflammation is going on somewhere within her body. It is unfortunately very possible that the stent could again become blocked.

Antibiotics may not be able to successfully knock down the infection in the area of the liver and bile duct - it's a very difficult area to treat - especially if the cancer has spread. If cancer is causing death and destruction to numbers of cells in that area the inflammatory process and the increasing amount of pus may be the result of the spread of the cancer. Has anyone in your family talked directly to the doctor about what is going on with the cancer and the prognosis? If not, it might be wise to do so.
