Who devised the Roux-en-y gastric bypass operation?

Hello nonnette

Dr. Edward E. Mason devised the Roux-en-y operation in the 1960s.
Later, he went on to develop an alternative procedure known as the
VBG.

"Roux-en-Y gastric bypass
First gastric restrictive operation developed many years ago by Dr. Edward Mason. "
http://www.newlifesurgery.org/overview.html

"gastric bypass surgery (aka roux-en-y)
[...]
The perfect middle-ground seemed to be another hybrid procedure
combining restriction and malabsorption called the gastric bypass,
developed by Dr. Edward Mason all the way back in 1966. "

"Dr. Edward Mason at the University of Iowa developed a modification
known as vertical banded gastroplasy (VBG) and published the first
results in 1982."

I hope this helps, but please let me know if you need any clarification.
