Thanks for the insight mothminor.
As I say, I'm out of the loop, last time I was anywhere near this field, there was some debate as to the value of (endoscopic) surveillance in Barretts.
Thankfully, things have moved on.
What I can provide is a primary care perspective. Two ends to the continuum really, scope no-one, or scope all.
We are, of course, somewhere in the middle, and the science is getting getting better all the time.
Good luck with your treatment.
