I had a robotic thymectomy in December 2011 in Chicago. They told me up to 4 days, and it was 4. As it turns out, they collapsed my lung purposely to gain more room to remove the thymus. I was 4 days in hospital because of the collapsed lung and making sure that everything was draining properly from that. The surgery itself and recuperation after I got home were fine. I took two weeks total off work, which I was glad I did because my stamina wasn't much. Overall I'm glad I did it, and feel like it was a pretty quick recovery. Best wishes to you!
