Mr Kerrigan told me that Aintree was one of three centres doing most of this work in the UK. Sheffield and Leeds being the other two sites. Go and have a look at the Leeds website. I think it presents the info in a real down to earth no-nonsense way. Compared to the USA Bariatric surgery over here is really a small speciality. I think the recently produced NICE guidelines will make a difference. Some docs and managers look on this as cosmetic surgery, Mr K describes it as a surgical intervention to prevent diabetes. Looked at that way it begins to make economic sense.
