Duodenal Switch Ten Year Results

**This graph shows the results
of a group of 120 patients which are all ten years or more since their
surgery. At the ten year point they had an average of 76% excess weight loss.
This is very good! In this graph we had follow-up of 111 patients of the 120
which is excellent
(92%) (July 2003)**

** Useful Definitions:**

**1) Percent Excess weight
loss** (%EWL);
This
is the percent of the weight above ideal that you lost. Example if you are over
weight by 120 pounds and you lost 100 pounds, then you would have (100/120)
x100% = 83.3 % EWL. This is very good since if you were more than 100 lbs
above ideal weight you now have a larger bone and muscle structure than some one
who was never over weight. You would not want to be down to the ideal weight,
it would be too low. (75% EWL) is good!

**2) significant number
follow-up;** You
will hear this term used frequently, this is the number of patients that were
counted in our results ether tables or graphs. It is important to have a large
number and percent of patients to get a true picture of the results. If you only
count ½ of the patients operated at a given time then it does not mean much, if
you have for example 75% of the patients then it has more importance and gives a
truer picture. Our 1^{st} graph of a possible 120 patients ten years or
more after surgery at the ten year point was 92% counted (111 of 120 possible
patients). This is very good follow-up results! With an average EWL of 76%
