Did you Google that information?
Yes, I googled some of what I posted. Are you disputing the accuracy of that information? Fine. If you know better, feel free to share your knowledge. If you have other information about expected recovery times after a major a surgery, I would appreciate knowing what you discovered. Based on what I know from experience is that recovery time is somewhat dependent on a patient's health and age. (which is logical, so there was no need to google it).
Several years ago, I had prostate cancer and chose to have the da Vinci robotic prostatectomy because it was less invasive with possibly fewer complications than traditional open surgery has. BTW, while I did not Google the da Vinci method before deciding on it, OMSI, the Oregon Museum of Science and Industry has a da Vinci robotic surgery simulator on display which visitors could use. After playing around with it, I prayed that my urologist had steadier hands than I did. LOL!
I believe I remember Wes either posted or sent me a PM me quite a while back that he was going to need the Whipple procedure. Just recently, he also posted that the surgery would take nine hours, which concurs with available information about the time involved in the Whipple procedure.
Before Google, back in the ancient times of my youth, I looked everything up in the Encyclopedia Britanica set which was on the bookshelf in our den, plus I often double checked the annual updates for accuracy.
