The sleeve procedure, which has a 50% success rate for patients keeping the weight off over time, will not help you in any way with your reflux. Essentially, all they are doing is removing a part of the stomach, leaving a vertical sleeve in place, but also leaving your duodenal switch is place as well. Nothing is rerouted and if you have heartburn or reflux, you may continue to have it as you adjust and recover. Bypass surgery, which has a 75% success rate for patients keeping the weight off over time, will eliminate both reflux and heartburn, as they reroute your system. The duodenal switch procedure, which has an 85% success rate, will do the same, as it is kind of a mix between the two surgeries, yet still incorporates a bit of rerouting that also eliminates the issue.
I personally went with the bypass for the elimination of both heartburn and reflux, as I was told that if I developed either I had a 95% chance of developing throat cancer within a year. It was deemed medically necessary as well for insurance purposes after having a scope done and examining my throat. I can tell you I don't have either, haven't had any issues with either since the surgery. I've since had another scope done and so long as I don't stretch out my new tummy over time, I won't be at risk for developing either condition. I can tell you a few of the pros and cons to bypass per my experience, but I'm sure I'll miss some! So far, the pros are that the tool works whether you want it to or not...which might for some be a con? Since things are rerouted, you have a tiny tummy, and if you eat too fast, too much, or the wrong kinds of foods, there is nothing stopping that new tiny tummy from causing either dumping syndrome or severe nausea and vomiting. So, yes, it works! If there is any chance you can't embrace your new lifestyle and move into the life of a protein based diet, don't waste your time on having the bypass done. People who sink back into bad habits of chocolate, sodas, chips, pasta, bread, etc. live a miserable life, because the tool keeps working. Because of that, old habits can make you sick on a daily basis. If you hear of bypass patients who are sick all the time a year out of surgery, a huge part of it is not eating properly.

Bypass surgery takes more time to recover from as well. I don't know if that is a con? I can't think of anything else at the moment but I do hope you are able to settle on what works for you! It is a big decision so best of luck on whichever you choose!
