I think that this all depends upon what your original surgeon meant by "no longer have a stomach just a pouch". A nominal RNY can be said to not have a functioning stomach, as the pouch is more of a flaccid funnel between the esophagus and intestine with a bit of restriction via the stoma to slow the food flow into the intestine, but it lacks a lot of the function of a normal stomach (hence the alternate term of a "gastric bypass". The remaining functioning stomach is left aside and sewn shut but is otherwise intact but non-functional. If that is what he meant, then you should be good to go to revise it to a DS.

If, however, he removed the entire remaining stomach, which happens occasionally, then there isn't anything left to restore the original stomach configuration to sleeve for the DS. Some other configuration may be possible, such as a distal, or long limb. RNY. Dr. K would certainly be able to tell you what is appropriate for your needs with what you currently have in you. If you have, or can get a copy of the surgical report on your original procedure, that would document exactly what was done; they are commonly available from the surgeon or hospital if done in the US, though not sure about if it was done in Mexico. That would save some scanning/probing to find out what you actually have.

Good luck, Dr. K is great to work with

it's a very complicated surgery that only a few surgeons are qualified to do. Dr. Keshishian is one of them. I don't know about Dr. Lopez, so be sure to do your research. As I understand it, they do a complete reversal of your RNY, then sleeve your stomach, then do the intestinal bypass part.

I saw you hadn't gotten any response. I did a quick google search and found nothing but references to old research papers. I would assume he retired.

he's one of the best DS surgeons in the country.

Actually it was 18 years ago - 2003. I had one of the best DS surgeons in the country do my procedure and had a great support system early out (and it does continue).

I have kept all my weight off. My only regain (about 3-4 years ago) was about 15 pound and I took it off by going back to basics - high protein, low carb and lots of water. I try to exercise but you know how that goes.

I've had two significant issues - I don't absorb oral iron so I have to keep a very close eye on my iron numbers (particularly ferritin). I have had infusions on and off over the last 15 years or so and it will always be something that I will deal with. It started pre-menopausal but continued after menopause. I was in my mid-40's when I had my DS. My anemia was really bad so through a series of procedures, I went into menopause, which has definitely helped (no bleeding - sorry TMI). My other issue is osteoporosis. I have significant bone loss even though I take massive amounts of calcium, try to do weight bearing exercise, etc. I'm getting ready to start Prolia treatments so we'll see if that helps.

For me personally the DS was 150% worth it. I always tell people to do their research. I never recommend a particular procedure but with the DS you MUST be willing to make a lifetime commitment to vitamins, labs, eating healthy for the DS, and just taking care of yourself. You have to find a procedure that you can live with FOR THE REST OF YOUR LIFE.
