Gastric bands are rarely removed but should it become necessary it is a straightforward procedure. As gastric banding does not alter the anatomy of the stomach, taking out the band does not involve the reconnection of any detached organs.
Gastric bypass reversal should be avoided. If we consider the original operation, the stomach is divided and most of it’s volume is cordoned off with staples. The stomach is rerouted to connect it to the middle of the small intestine. To reverse this at a later date the surgeon must divide the stomach and the intestine where they had been sewn together and use a stapling device to rejoin them in the original spot. However, the stomach will not be the same as it was before the gastric bypass as it is impossible to mend several nerves that help with normal gastric function.
When would surgeons reverse gastric bypass surgery?
Only when the patient experiences significant complications such as infection, a hernia (along the original incision), a leaking stomach (that has been punctured during surgery), malnutrition (because a portion of the small intestine is no longer in use).
Gastric bands carry fewer risks because they are less invasive.

This is a subject constantly debated between medics at NOSC. The conclusion to any discussion regarding gastric band versus gastric bypass is always the same. We fail to see the justification in offering anyone a gastric bypass when there is a safer, less invasive surgery available. Adding weight to our argument is the data that shows the percentage of gastric bypass patients who have regained their weight after a period of 5 years. As a gastric band is adjustable, the patient has a lifetime of control.
And for those patients who want the quickest and easiest procedure, we suggest they choose the gastric balloon!
