Debbie,
First, I agree with tongrenhealer. Choose the least invasive, effective option.
Second, the long-term outcome of surgery depends on too many variables to list, however an important one is the overall condition of the patient going in. I won't even pretend to have the answers, but as one who has been through it, I have opinions. I had the traditional Ivor-Lewis esophagogastrectomy (esophagectomy) in July 2005, at the age of 54. I had no chemo or radiation at any time. I was in very good condition going in and had no complications. I returned to work in 10 weeks. If I did the kind of work your husband does it would've been more like 3 months - not sooner! I had no effect on my voice at any time. (Of course, I sing like a frog anyway so who would notice.)
Again, I don't do physical work but feel much better when I move. I expect to post a message on this site, by July, saying that I've cycled 10,000 miles in the three years since surgery. I have transplanted trees and feel good afterwards. I think your husband has a good chance of returning to his current job and doing well. The physical work may actually be therapeutic.
Don't forget to take care of yourself!!
Keep us posted. There are lots of people to help you on this site.
Good luck to you and your husband, KEEP MOVING,
Steve
