That was my thinking but I was told all blood supply is cut off to the area in some surgeries depending on how the procedure was done.
In the standard Roux the stomach is sectioned off and left intact including the blood supply as seen here: http://www.laparoscopy.com/obesity/roux.html
In the lap band there is no resection and the blood supply is unaffected as can be seen here: http://www.obesitylapbandsurgery.com/tecmain.html
There are older surgeries such as gastric stapling which involved running rows of staples and partitioning the stomach. There were a number of problems with these and they have largely been abandoned. The lower picture on this page shows the older style: http://images.google.com/imgres?imgu...3D35H%26sa%3DN
Bottom line is that the stomach has multiple blood supplies. It is very hard to disrupt them. When we did a Nissan fundoplication the surgeon would divide the short gastrics without any problems. There is a diagram of the blood supply in the middle of the page here: http://en.wikipedia.org/wiki/Stomach
