Okay, so I was too pooped last night when I came home to be able to sort out my notes.
In the US, the data is the latest, for 2005, I think, it's still to early to get the 2006 data.
Roux en Y bypass 77%
Lap banding 16%
Sleeve gastrectomy 3%
others (Duodenal switch, Biliopancreatic diversion)
Consider all that can be done either open and lap as combined, the slides went by too fast for me to get everything correctly, I shoulda taken my camera along!!! (Yuck, after thought, they usually provide an abstract for the lectures, but the ones for the foreign speakers were incomplete...

)
Here's the link for the types of surgery page of the weight loss center the speaker belongs to.
Weill Cornell Weight Loss Surgery: Healthcare Services
Also the link to the NIH guideline for bariatric surgery. It gives a summary of the major types of surgery, but sleeve is not included in this yet.
WIN - Publication - Gastrointestinal Surgery for Severe Obesity
I have also put up a post explaining the sleeve gastrectomy here.

Mini gastric bypass is a procedure done only by certain surgeons in Taiwan (Formosa) because they felt the procedure better for the Taiwanese whose pre-op medical issues are somewhat different from the Americans. I understand the differences, but I'm not going to go there here, it's probably going to be too complicated, need to explain too much things. The surgeon who does the mini-gastric bypass was at the workshop yesterday.
I need to sort through the notes I took yesterday, it is messy

and I am having fun trying to decipher it, remembering what was said.
