I just saw your post and wanted to let you know that another member on the forum, [@Simon77], has had experience of recovering from surgery for oesophageal cancer and now that I've tagged him in this post I'm sure he will be along when he can to share his advice and experiences with you.
Our cancer nurses are only a phone call away if you would like to discuss this with them as well. Their freephone number is 0808 800 4040 and they are available Monday - Friday between 9.am - 5p.m.
I hope this helps Linda and that the recovery goes well.
