Comparison of Gastric Banding and Gastric Bypass Surgeries


Gastric Banding

Gastric Bypass

Graphical Representation

Anatomy

A band made of adjustable silicon, has been inserted around the stomach as to form a small stomach pouch of approximately 15-20 ml.

The stomach is divided into two parts as to form a pouch of approximately 20-30 ml and this small stomach is connected to the intestine.

Weight Loss Mechanism

Food intake decreases due to restruction of the stomach volume and it can be well decreased by adjusting of the staple.

Food intake decreases due to restruction of the stomach volume and also digestion of the foods decreases because of the foods have taken directly pass down from small stomach to the intestine.

Weiht Loss Rates

50-60% of the excess weight is lost at 18-24 months period.


70-80% of the excess weight is lost at 18-24 months period.

Diet and Required Life Style Changes

High calorie diet (chocolate, icecream, desert etc) should be avoided. Regular exercises should be done in the forward periods.


High protein foods must be taken in the beginning, sugar foods should be avoided (dumping syndrome) and regular additional vitamins must be taken against to lack of vitamin and minerals. Regular exercises should be done in the forward periods.

Nutritional and Vitamin Requirements

Multivitamin, Calcium (rarely)

Multivitamin, Calcium, Vitamin B12, Iron

Surgery risks

Surgery risk rate of early and late period %0-8

Surgery risk rate of early and late period %0.2-10

Eating Adaptation

May be difficult, frequently nausea and vomittings may be experienced

There is usually more qualitied and easier eating adaptation.

Technical Difficulties

No

Yes (a difficult application, more training and surgery practises are required)

Prosthetics (Foreign) Material

Yes (there is silicon material but it’s adaptation is quite good, the reservoir sometimes may create problems)

No


Reversing of the surgery

Yes

Yes (but quite difficult)
