Hi Brenda
I am approved to have DS at St. Joe's. I don't have my surgery date yet. My surgery will be with Dr. Hong who I understand is the only surgeon in Ontario who does the DS. Here is what I posted a couple of weeks ago:
"To my knowledge, Dr. Hong is the only surgeon in Ontario who does the DS surgery. RNY is the "gold standard" so this is why this is the main surgery offered at the bariatric centres, including St. Joe's. The DS surgery is much longer (5 hours instead of 2 for RNY) and much trickier as a result of how they create the "common channel" (the part of the bowel that allows for absorption and mixing of gastric juices and food). DS isn't appropriate for every patient, so I get the sense that Dr. Hong waits for a patient to suggest it which shows that we've done the research to understand the procedures and what we feel is best for ourselves.
I did a lot of research about duodenal switch surgery in comparison to RNY and looked at many of the available studies (
http://weightlosssurgery.proboards.com/index.cgi?board=dsdat a). DS has typically been used for folks who have a BMI over 50 and at least one comorbidity. The big one is diabetes and DS is seen as being the best procedure for folks with this condition and curing diabetes quite quickly after surgery. I didn't meet either of these criteria for BMI or diabetes, but argued that my BMI is high enough (47) and DS has better statistics for longer term prevention of diabetes, high cholesterol and high blood pressure (which all run in my family). Dr. Hong seems really reasonable in giving patients some say in the surgery they get so he was open to my arguments and approved me. DS is highly malabsorptive so his big thing is making sure patients are absolutely committed to taking vitamin supplementation for the rest of their lives and getting at least annual blood work for any deficiencies - there is much less "wiggle room" in this regard compared to RNY. Dr. Hong also takes out the gallbladder right away during DS surgery because it's a hard organ to get at later if it acts up. Dr. Hong also said there's a 20% chance he might have to the DS in two stages - the VSG in the first surgery and then a 2nd surgery in 1 year for the "switch". I'm really hoping that doesn't happen to me.
One of the OH members, PatXYZ is also very knowledgeable about DS and helped walk me through all of the details.
If folks have other questions, please let me know (private message works too) :)
Take care
