I have not found great information on long term (10 years) results with the sleeve. I understand its relatively new but I thought maybe some of you might have received this info from your Docs. I'm probably just not searching with the proper words. Thank you for any help on this.

stand alone sleeve isn't that old. It was just becoming popular when I got my RNY six years ago - it was becoming the non-RNY replacement for the lapband. It'd been around longer than that, but I don't think much.

if you want longer-term stats, maybe research the DS (duodenal switch). The DS is an old surgery, and it uses a sleeved stomach. In fact, that's where they got the idea for the standalone sleeve. The DS used to be done in two stages (usually - not always). They do a sleeved stomach and then later go back in and bypass the small intestine (now most DS's are done in one surgery). They discovered that a lot of people lost weight with just the phase 1 (sleeved stomach), so they started offering that as a standalone surgery.

Thank you, and the history on it is interesting.
