On one of the posts I was reading yesterday where someone asked if the Sleeve or the RNY was better, several ppl said that the pouch in the RNY stretches more than the sleeve.

I was just wondering where you got this information, because my surgeon did say we had to be careful not to stretch out the sleeve, and even that one time he had to perform a 2nd surgery to to make the sleeve smaller again after his patient had stretched it out. Also, I couldn't find anything on the internet to verify this. Several ppl posted that as their answer so I was just wondering where they got the information.

The pouch created during a Roux en Y bypass is made from the fundus of the stomach, the stretchy part, and an artificial opening, called a stoma, is created at the bottom of the pouch and connected to the small intestine. In the VSG, the stretchy part of the stomach is cut away and the stomach in sutured close to the lesser curvature, which is more like muscle tissue. There is a little stretchy part at the bottom of the stomach where the pyloric valve is and at the top where the stomach meets the esophagus, but mostly it's tough, fibrous tissue that's left. In RnY patients the pouch can stretch and the stoma can stretch. In VSG, the stomach tissue swelling goes down and the stomach does increase in volume, but will never hold anywhere near as much as an unsleeved stomach. Poor diet choices can sabotage any WLS--VSG or RnY, you'll gain weight on a diet of milkshakes and Cookies.

If you google Roux en Y and VSG, there are some sites which will show you the surgery and the re-routing in RnY. "Fundus" should get you the info about that part being stretchy.
