Potential Advantages:
People are attracted to the fact no re routing of the intestine takes place with a Gastric Sleeve.
There may be less vitamin and mineral deficiency issues as there is no malabsorption component. There
is no foreign device that requires adjustments as in gastric banding. Technically, the procedure is easier to
do than either banding or bypass and may result in a shorter hospital stay. Removal of 70 % of the stomach reduces hormones
that cause hunger.
Potential Disadvantages:
Although weight
loss results are usually better than banding, they are probably less than usually achieved with bypass.
The long staple line along the stomach can leak. The body of the stomach is removed, gone forever, and not reversible
although if weight loss is not good, RNY bypass can still be done.
