Do you think the surgeons would allow someone to compile data about all the patients who are 20+ years out across all the known surgeons, and determine their outcomes? If they would each send the a single, validated survey to all the long-timers, and the completed surveys were all sent to one researcher, the very long-term outcomes could be tallied and compared to an obese population without surgery. It can't be more than 1000 patients do you think? how could one best contact the surgeons to propose such a study? Some surgeons are dead or have changed hospitals, but there might be a way to get someone who is taking care of their patients to contribute (without identifying patient name for privacy). I think we all would be interested in ultra-long term outcomes in terms of complications, life expectancy, weight regain, quality of life, etc. I believe we know outcomes of shorter-term patients in one surgeon's practice, but I haven't seen anything of all the first patients at this length of time. Does anyone know what happened to Satori Jane, a very long timer who had a great DS blog that's I used to follow before it disappeared? Probably a crazy idea to study those who were brave enough to leap into the unknown at that time.
