I just had my sleeve redone, I had a very large sleeve and I had it made smaller. With images in hand I would seek a 2nd and 3rd opinion. I am not very good are "reading" x rays but comparing what my sleeve looks like to yours, yours seems rounder. Again it may be something else I am looking at but have an expert read it with a different perspective.
What may seem large to one may be normal to another one. Some surgeons do smaller sleeves. For some surgeons losing 60 % excess weight may be a success for others success is 90% of EWL. While 60 lbs is very good weight loss if it is not enough for you keep looking. It may be that you need o change habits but it may very well be that your sleeve is too big.
When I knew my sleeve was too big I searched for revision surgeons that had experience in making sleeves smaller.
With my new sleeve I can see a huge difference in restriction. I now know what I should have done originally. 40 lbs less in 2 months and I can say that this is what I had always needed.
