Hi Susan
My tumor was in the head of the pancreas also,my Surgery started at 8AM and I was in the ward at 900 pm after recovery I was in hospital about three weeks,but as you say we all have different recovery times,they want you up and out of bed as soon as possible and walking a few steps that is very important for recovery, Mum may not feel like it but you can help there,her pain will be taken care of by the medications I remember floating in and out after surgery for days, if she has pain ask and they will adjust the dose,she will not eat for days that comes after,before starting solids ask for a stool softener, I did not know about that,and on reflection it is a must,to stop straining.I did not need rehabilitation, some people need intensive care some do not,also do not be alarmed by all of the tubes,we all had them if your Mum is in intensive care she will be well looked after.
My recovery from the surgery took months when I came home, eating food takes awhile as your tummy has changed and food volumes and taste are not the same it takes a while to adjust, so just be patient for Mum and lots of support and encouragement which I can tell you will provide, I know I needed time to adjust to the new me and needed TLC from my family you are physically tired and emotionally fragile after a Whipple.
Hope this helps explains parts of a Whipple and the after effects.
Will be thinking of your Mum Friday Good Wellness
