Purses,
The surgery your husband will have is called Whipple surgery; he is very lucky that he is one of the 15-20% able to have this procedure. Yes, the organs you mentioned that will be removed are those commonly taken during the Whipple, as well as possibly part of the stomach and duodenum as well. You can find out much more about this surgery and pancreatic cancer in general at the Johns Hopkins web site. Johns Hopkins also maintains a Pancreatic Cancer Online Support Group that is very helpful. There are both patients and caregivers with much knowledge who are happy to share their info as well as provide support.
I suggest you would be wise to have a 2nd opinion for your follow-up care; it is the standard of care in the US to have both adjuvant chemo and radiation. Pancreatic cancer is a very aggressive cancer and is known to recur so you would be wise to have follow-up treatment. Many surgeons and institutions are not expert in the treatment of pc, and experts are what is needed when you are dealing with this terrible cancer. I do not know who your surgeon is, but he or she should have done LOTS of Whipples; it is in your best interest to ask that question of your doctor. The hospital you choose should also have an excellent record with pc treatment.
How soon your husband will be able to return to work depends entirely on him; is is very subjective. Almost everyone has some issue or other but a few patients return to work after about 8 weeks, depending upon their reaction to adjuvant chemo and radiation. He will have to learn how to eat again with his new plumbing and will no doubt lose weight after surgery as most patients do.
Visit the Johns Hopkins web site and support board. There is so much there to be learned. There is also an organization called PanCan which will send you info on doctors, diet, etc. You can google their name for their website and phone number.
Good luck.
