Can anyone provide me with the number of DS surgeries performed annually in the US if they have it handy?

Someone asked me at work and I'm snowed under with work so I can't go hunting info atm

Thanks

Felt the need for a break from doing 125 employee reviews so I came across.......

***
In 2008, 344,221 bariatric surgery operations (all procedures) were performed by 4,680 bariatric surgeons; 220,000 of these operations were performed in USA/Canada by 1,625 surgeons.

In the year 2008 alone, 6,800+ open and laparoscopic DS procedures were done worldwide.

In 2003 alone, 6,600+ DSs were done just in the US/Canada and Europe.

At roughly 6,500 a year, even in the last 10 years alone, that would be a guesstimate of 60,500, more or less.

Hess developed it in 1988, but it grew slowly, so I'm not counting the first decade or so.

If any of our DS peeps have any further info I would appreciate it

Thanks

Ian

I don't think that the DS of 1988 is the same as the DS of today.. From what I remember that surgery way back then was pretty scary and unsafe.. it is way better now.  So the last decade would be correct to count vs anything before that - I think..   

DSrs?

Obes Surg. 2007 Nov;17(11):1421-30.
Duodenal switch: long-term results.

Marceau P, Biron S, Hould FS, Lebel S, Marceau S, Lescelleur O, Biertho L, Simard S.

Department of Surgery, Laval University, Laval Hospital, Québec, Canada. picard.marceau@chg.ulaval.ca
Abstract

BACKGROUND: This report summarizes our 15-year experience with duodenal switch (DS) as a primary procedure on 1,423 patients from 1992 to 2005.

METHODS: Within the last 2 years, follow-up of these patients, including clinical biochemistry evaluation by us or by their local physician is 97%.

RESULTS:
Survival rate was 92% after DS. The risk of death (Excess Hazard Ratio (EHR)) was 1.2, almost that of the general population. After a mean of 7.3 years (range 2-15), 92% of patients with an initial BMI < or = 50 kg/m2 obtained a BMI < 35 and 83% of those with an initial BMI > 50 obtained a BMI < 40. Diabetes was cured (i.e. medication was discontinued) in 92% and medication decreased in the others. The use of the CPAP apparatus was discontinued in 90%, medication for asthma was decreased in 88%, and the prevalence of a cardiac risk index > 5 was decreased by 86%. Patients' satisfaction in regard to weight loss was graded 3.6 on a basis of 5, and 95% of patients were satisfied with the overall results. Operative mortality was 1% which is comparable with gastric bypass surgery. The need for revision for malnutrition was rare (0.7%) and total reversal was exceptional (0.2%). Failure to lose > 25% of initial excess weight was 1.3%. Revision for failure to lose sufficient weight was needed in only 1.5%. Severe anemia, deficiency in vitamins or bone damage were exceptional, easily treatable, preventable and no permanent damage was documented.

CONCLUSION: In the long-term, DS was very efficient in terms of cure rate for morbid obesity and its comorbidities. In terms of risk/benefit, DS was very successful with an appropriate system of follow-up.

so according to those numbers Ian, DS has been on the decline?

Hmmm.. I guess the only way you could figure that from the info Ian posted would be to infer that the 'worldwide' in the first number is only US/Canada.. 

In the year 2008 alone, 6,800+ open and laparoscopic DS procedures were done worldwide.

In 2003 alone, 6,600+ DSs were done just in the US/Canada and Europe.


Could be that only a percentage of that first number actually were in US/Canada so the DS could be on the rise vs decline.

Right... if there were only 6800 done worldwide in 2008, but nearly as many just in the US/Canada in 2003, that would seem to imply a decline..  it could be trending back up now though.

so according to those numbers Ian, DS has been on the decline?

Haha.. I didn't even really pay attention to the 2nd date.. just figured it was after 2008 cuz that is how my brain works.  Now I see that it is actually BEFORE 2008.. carry on!  nevermind me.

Check  www.duodenalswitch.com  for facts.  This is Dr. Douglas Hess's site - he is the surgeon who made the modifications to the old BPD/DS (Scopinaro procedure) to the DS (Hess method)  that we have today.

Dr. Hess is still around, though retired, and would make a great interview for Bariatric TV!  Thanks to this barioatric pioneer, thousands have gotten back their lives, or as in my case, are REALLY living for the first time!
