BACKGROUND: Gastric bypass (GB) is the most common surgical procedure for weight loss in the United States. Biliopancreatic diversion with duodenal switch (BPD/DS) is less routinely performed, perhaps because of its technical difficulty and metabolic concerns. The objective of this study was to determine whether these procedures had differential effects on weight loss and body composition. METHODS: Body composition was measured by bioimpedance (Tanita 310) at the initial consultation, and follow-up measurements were completed 1-2 years after surgery. RESULTS: Of the 72 patients in the study, 50, aged 46.2 +/- 8.5 years, had undergone GB and were measured 15.5 +/- 5.2 months after surgery and 22, aged 40.6 +/- 7.9 years, had undergone BPD/DS and were measured 19.5 +/- 7.5 months after surgery. Patient age and time after surgery were significantly different between the 2 groups. The body mass index (BMI) for the BPD/DS group was 53.6 +/- 11.9 kg/m(2), significantly greater than the BMI of the GB group (48.0 +/- 6.3 kg/m(2); P = .009). However, the percentage of body fat did not differ between the 2 groups (P = .515). Postoperatively, the BMIs for the GB group (31.5 +/- 5.0 kg/m(2)) and BPD/DS group (30.3 +/- 6.1 kg/m(2)) were not significantly different (P = .384). The percentage of body fat for the GB and BPD/DS groups had changed from 49.2% +/- 8.3% to 32.1% +/- 10.6% and 47.9% +/- 5.9% to 23.8% +/- 10.4%, respectively (P = .002). The BMI had decreased by 16.5 +/- 4.8 kg/m(2)after GB and 23.3 +/- 6.8 kg/m(2) after BPD/DS (P <.001). The decrease in fat was 17.1% +/- 8.2% after GB and 24.2% +/- 7.2% after BPD/DS (P <.001).

CONCLUSION: The BPD/DS procedure is more effective in reducing the BMI and promoting fat loss than is Gastric Bypass. The assessment of the impact of these two operations on an individualized basis offers additional information to assist in the evaluation of these procedures.

Can I ask why you are posting studies here?  Are you trying to convince yourself or others?  I guess I just don't understand why you are doing this I didn't see a post asking for studies?  Just a question I'm not trying to be rude.

Sally,

This is the Minnesota Forum.  I live in Minnesota.  I've lived in Minnesota for 40 years and 4 months (that'd be my entire life).  My Surgeon is at the University of Minnesota.  My hospital is Fairview University in Minneapolis, Minnesota.  My health care insurance is Minnesota based, HealthPartners.

Isn't that the only requirement to post here, or is that even a requirement to post in a state forum? 

The better question is why would a scholarly journal post on bariatric surgeries and long term effectiveness of the different procedures; be offensive to you or any other Minnesotan?

I don't care what surgery you had, and I most certainly don't need any convincing on the duodenal switch, as I am an RN who has researched weight loss surgery for the past 7 years.  Check how long I have been an OH member! 

The best thing that overweight and obese people can do is study, read, reasearch, learn all that you can before you make a decision. 

Where is the best information on which to base a decision for bariatric surgeries?  It is in, scholarly Journal Studies and scientific articles.  

People don't ask about my bowel habits, but I post information on that too.  I don't have to have a question, in order to propose a solution, Sally.

PS:  God Bless ya, and I hope you have wonderful results from your weight loss surgery!!  Truly!

You too - I just diagree with how you posted is all.  But we will agree to disagree on posting techniques because I certainly do not disagree with the studies you posted.
take care

Posting techniques and how I posted.....

Not sure I could post with any less offensiveness, by copying and pasting the exact quotes and exact journal article text.

...WITHOUT A SHRED OF PERSONAL INPUT.  THERE WAS NOT ONE COMMENTARY OF MY OWN. 

 

Maybe not as classy as Darla would like it, but posting this study is meaningful.  If someone hadn't come on this board and told me about the DS, I wouldn't have gotten the WLS that was a fit for me.  Not everyone knows about the DS, which is a shame in MN.  We have 2 (working on 3) DS surgeons - a luxury many states don't have.  If this post makes one pre-op/newbie aware of a surgery that may be a better fit for them, this is the perfect place to post it and a perfect state to live in.  If a pre-op didn't KNOW about a surgery other than LapBand or RnY (like myself), they wouldn't KNOW to ASK about the surgery, let alone ask for a study.  I was clueless on this board until someone steered me to the DS and the DS forum.  I'm glad someone is taking the initiate to let other pre-ops an alternative.  Everyone always say, no surgery is perfect for everyone - you need to get the one that fits you.  But first you've got to know there is more than one.

Sandy - twas a great post
