I'm need an urgent consultant regarding authorship rights. Three years ago one of my professors asked me to write a surgical case report for one of his residents, later I found three similar cases and added to the article. I collected all data and followed all cases alone. The professor only gave the idea and neither the professor nor his resident made any contribution to writing the article or even reading what I've written. At last, they said this case in not worth publishing and we are not interested to publish your manuscript. They gave me permission to publish the article myself but the only document I have is a text message. Tonight, I got acceptance of my article and I want to make sure that I can publish that without the name of the surgeon. I have aknowledged their name.
My take from your description is that the surgeon gave you his clear permission to publish without his name attached -- in the form of a written text message. Assuming that the wording in the text message is unambiguous, there ought to be nothing for you to worry about: He's expressed his opinion, and you're free to proceed.
