Someone With Google Foo

 Ok so someone on the main board just corrected me when I said the fundus was the stretchiest part of the stomach and also they part of the stomach the RNY pouch is made out of.  I'm pretty sure I'm not wrong, but if I am I would like something besides OH and yahoo.answers to look at.  I've used all my Google Foo and nothing, can't find an answer at all.  


So anyone got a link to something that gives me a concrete answer?

 From what I understand it is the outer curvature of the BODY of the stomach that is the stretchiest, that the inner curvature and the top (fundus) and bottom (pyloric, including the valve) of the stomach are pretty solid muscle that won't stretch all that much. 

The risk in RNY is not really that the small pouch will stretch, but that the stoma that is created by the attachment of intestines will get bigger over time allowing for more food to pass from the stomach to the intestines in a shorter period of time. 

I am no expert though, this is just stuff I have picked up from my obsessive research and reading about WLS LOL

 Ok, any ideas as to where to get that in writing?  I found similar information but it was all here so the fact checker in me would like to see it somewhere a bit more fact based.

I am looking, but I can't find anything peer reviwed on the subject. 

 I can't find anything not on here and yahoo!  Not exactly valled sources.  I'm glad I'm not the only one who is having the issue.  I think it may be search terms, because most of what I get is how to get rid of stretch marks!

Hope this helps!

 The first couple I've seen but they don't point out what the stretchiest parts are.  I couldnt' get the PP to work.

I will see if I can find the diagram I posted way back under another name.. The RNY pouch is made along the lesser curvature at the top of the stomach- where ours is the entire length of the lesser curvature. The RNY pouch is about the size of a golf ball or chicken egg, and really does not stretch much.. the stoma can however, that's what tends to happen when someone loses restriction, but yes- the RNY pouch is also a non-stretchy man-made receptacle. 

Ok, I'm sure I can find something better with more googling.. but here's a great diagram for just a look-see.. the lesser curvature is the least stretchy part- the fundus- the big rounded out portion that extends above and away from the main section is the tissue that is balloon-like, and expandable.. the RNY pouch is formed from the least stretchy portion, as is the VSG stomach, just the VSG stomach is longer.. now- can they stretch? Debatable.. and depending on how it was created to start with- just like the VSG. Both "dilate" aka stretch or grow over time, going from a new-surgery relative average of 2oz to 6-10oz or so at maturity.. just as with the VSG, surgical technique will determine how much tissue is retained, and that will effect the overall end size.. but all in all- volume & stretchiness wise- they are about the same.. The VSG may actually be more prone to stretch due to the ability of the surgeon to leave more fundus along the entire curve - or to leave too large of an area at the top or bottom of the stomach.. where the RNY downfall is a stoma that does stretch in a number of cases and cannot be tightened back up- allowing the pouch and intestine to become one large stomach. You will find references to both "pouch-stretching" and VSG stomach stretching, as they both do mature to a larger size than they were originally created.. but I highly doubt you'll find any concrete links to the opposite- that they cannot or do not stretch.

Here you go, searching "lesser curvature roux en y" gives you several decent hits, this is one:
