Question:
Has a study been done on the short and long term effects of the Duodenal Switch?
I would like to find information on the Duodenal Switch, specifically if any studies have been conducted by INDEPENDENT researchers. Ive read a lot of testimonials from doctors but it seems like any doctor is going to talk up whatever surgery he specializes in. Have any independent studies been made comparing the DS with the proximal RNY relating to maintained longterm weight loss, malabsorption problems, vitamin deficiencies, complications, etc.? The thought of eating more with the DS sounds great but where do all those extra calories go? Also, wont the DS stomach stretch over time just like the RNY pouch? That could turn into a fair sized stomach. I read that the DS is in common practice in Europe. Maybe some longterm studies have been done there. — [Anonymous] (posted on March 8, 2000)

I am currently speaking to my surgeon, Dr. Baltasar, about studies, essays,
reports, etc he has done over the years about the DS. He just got back
from heading up a meeting and is pretty tired. He said he will get back
with me in a few days. The thing is, most of these will be in Spanish,
since he is from Spain, but my husband, who is also from Spain will help
with the translations. I know there are some in English as well. As soon
as I get something from him, I will let you know, ok?

What is your definition of an independent researcher? I would be hesitant
to value any report/essay/study on these procedures in which bariatric
surgeons are not involved. We must remember that data, facts and
statistics, can be massaged. The ASBS will have a brochure published by
Summer 2000 describing each procedure's pros and cons. I suggest you do
your own research and draw your own conclusions. Get two or three opinions
on each procedure. Many surgeons have web sites you can visit. Many
surgeons have an informational packet you can request by mail. You'll have
medical information about each procedure and can determine what's best for
you based on your eating habits, motivation for exercise and following
post-op instructions, and weight loss goals. Also check out the National
Institutes of Health endorsement of bariatric surgery. Ray Hooks had an
excellent post a while back citing Internet and other resources. Good luck
in your quest for knowledge!

Both of the reports that Melanie cites are studies published in
international peer review journals. While I agree that numbers can be
"massaged" (Dr. Rutledge's website is an excellent example),
studies published in a scientific peer review journal are held to a much
higher standard and are scrutinized closely by surgeons all over the world.
A surgeon would have nothing to gain and everything to lose by publishing
false or misleading information in such a forum. I recommend to all folks
researching different procedures that you not only consider the source, but
also the medium. If the information is from a surgeon's website, then of
course the information is going to be "publicity-oriented". If
the information is in a scientific peer review journal, then YOU, as a
consumer, are not the intended audience - other surgeons are. I leave you
to draw your own conclusions.
