There is so much more information available online and medical research since I was first diagnosed in 2005 it's hard to keep a track of any advances.
Back in 05, I remember doing an internet search and I only found one page and the originator was in SWEDEN!!
I've found some fantastic support groups as well online and on Facebook (AAO - Achalasia Awareness Org) we all tend to keep each other updated. There's a focus/support group that is held in London on a monthly basis with special guest speakers, experts in the field of Achalasia. I can provide details if you want to contact me via this site.
