Realize Band vs. Lap-Band
Both bands function exactly the same. The Lap-Band has been improved for a longer time in the USA. Most of the bands placed in the USA are Lap-Band and not Realize. I prefer to use the Lap-band in my patients because I think it is a better designed band. The Realize band recently had a recall.
There is not a landmark paper that stablished one type of band as superior to the other. I think the use has to do with the preference of the surgeon. The principle is the same for both bands even though they may some aesthetic differences.
