I have heard from a few very reliable sources that Yau never left Slimband. He was in the OR last Monday. They are not being truthful to his patents when they tell them he is no longer associated with Slimband. I wonder why?

Ghost surgeons are real. Some surgeons allow other surgeons to sit in on their surgery as advisors or even to do difficult technical procedures. The primary surgeon is held accountable for any mishaps. Yau could be working for any of the particpants such as Slimband, the primary surgeon or even the hospital as a contract surgeon case by case.

Anyway, that's how it works here in the States? May be different up North?

I agree with 2muchfun. I was one of Yau's patients and met with a new surgeon there last month. Yau could simply be honouring some commitments he made awhile back. I don't think Slmiband is being deceitful.
