Cross between DS & BPD is what I ended up with...

So this forum must be just for me...
I researched for over a year & even flew across the Country from NJ to WA state to have my laproscopic (DS) Duodenal Switch. 
There were complications & the staple gun misfired. The surgical team had to open me up to try to fix the what went wrong.
When they were trying to attatch the small intestine, the doctor said "it was like sewing up wet bread" none of the staples/stitches, would hold and they had to keep moving up to try to find solid healthy tissue. They ended up taking my doudenum stump and my pyloric valve to get to solid healthy tissue into the bottom of the stomach. So I still have the longer banana shaped stomach (Not a small pouch) My food does the normal digestion/breakdown process (from stomach acid) as it travels down the stomach - I don't have dumping syndrome (doctors wondered if I would). And the liver bile combines with the food in my 75 mm common channel as a normal DS.
I lost 100 lbs in six months. Follow up with Dr. Greenbaum I was losing 16 lbs per month & he wanted to slow the weightloss down so he put me on creon - which I took for about six weeks as I adjusted to adding more food - another meal & snacks & stopped taking the creon. I have currently stayed at a loss of 120 lbs. from 258 down to 138. I am currently 1 year & 5 month out from my surgery & I eat anything I want & try to go to the gym about 4 days per week for an hour on the tread mill. I am moving back to WA state & will go back to see my original surgeon; Dr. Matthew Martin at Madigan Army Medical center for follow up.
I did not get the surgery I wanted, but thankfully so far I seem to be healthy - I do take 4 handfuls of vitamins recommendations fromVitalady, and haven't had any more complications other than some kidney stones which I did a nutrition cleanse for. I feel God has blessed me with my health & I chose to work out so I can enjoy the foods I want. I was in a 22-24 & now comfortably wear a size 8. I also enjoy having the extra energy to spend more time in activities with my family.
I am interested in seeing what my labs look like when I get to WA in the next month.

WOWZERS that must have been a heck of a jolt :-(. Did Dr. M. explain why the search for good tissue was so problematic?

Yes, it was - after all the research I did & flying across the Country to get my DS. No, I think it may have had something to do with the staple gun misfiring, but don't know for sure why the tissue was not holding.  Hopefully I'll get some more answers and hear good news on my labs once we get moved back out to WA.

I wonder if maybe some of our DS board medical folks can shed some light on how that might happen.

congrats on your weight loss!
sounds like you have had quite the experience!!

Do you know how many DS's that Martin performed?
I heard that duodenum tissue is like trying to suture together toilet paper... extremely difficult!

Dr M has done LOTS of them. He's in my neck of the woods, so we see many of his ppl. He was doing them before he came to our area.

If you're thinking he's wet behind the ears, nope. Even the best docs run into surprises when they get to poking around.

Sounds like he did his best to give her as close to a true DS as possible. Most docs when faced with this would just cut to the chase, RNY, bam, done. Next?

The only reason that I know for "tissue squish" is lowish protein. My doc started protein loading us back in about 1999. Altho he said it was for US , I think it was much easier for him, especially revisions. He said the difference was the tissue-y gook vs soft pliable suede.

And I'm not blaming the patient! Some ppl just don't have much protein on board, even pre-op. I didn't. The good part is that I don't have to hold myself to some lofty pre-op standard. LOL
