I am the same as Caroline, a band to mini bypass. It was the best op for me because I had severe reflux symptoms, this does not mean just heartburn. I coughed all day, sore throat, lost my voice, was breathless after one flight of stairs etc. A sleeve is not recommended for anyone with reflux. It is also reversible which the sleeve is not. Having said that the MGB actually uses a sleeve as a stomach as well as bypassing part of the intestines. I am one week out and healing well.
Good luck with getting your band sorted, whatever you choose. X
