How does it work: |
Food intake is reduced.
Controlled malabsorption.
Small diarrheas if excess of sugars or fats. |
Food intake is reduced.
NO malabsorption
/diarrheas.
Natural stomach function is maintained. |
Food intake is reduced.
Delays stomach emptying
Needs permanent prosthetic device for life |
Weight loss: |
70-80% excess weight.
Most proven and tested operation. |
65%-70% excess weight.
Longest experience is 6 years. |
50% excess weight.
Requires the most effort by the patient. |
Long term dietetic habits modification |
Initial intake is about 800 cal/day over 18 months.
After a while 1000-1200 calories/day.
Most patients must stay away from sweets and fatty foods to avoid "Dumping”
Vitamins are needed, Fe, Ca, to compensate for reduced absorption of essential nutrients. |
Initial intake is about
600-800 cal/day over 12 months.
After a while 1000-1200 calories/day
No dumping, no
diarrhea
No vitamins or supplements needed for life |
Initial intake is about 800 cal/day and after a while 1000-1200 calories/day
When eating too fast, certain foods (rice, bread, dried meats, popcorn…) can cause pain and vomiting.
If eating habits are not modified, the weight loss can be regained. |
Potential Problems |
Dumping syndrome
Stenosis or anastomotic ulcer
Intestinal Obstruction.
Nutritional deficiencies :Iron, Vitamin B12, Folic Acid
Diarrhea |
Reflux and regurgitation/ vomiting.
Stenosis
Regaining weight loss
Additional procedure might be needed |
Too little weight loss
Band Slippage 3%
Stomach erosion 1%
Infection 1%
Access port problems 2%
Band and esophagus malfunctioning |
Procedure duration |

Our recommendation |
Most efficient treatment for BMI of 45-55, when patient can’t control sweets and snacks.
However, this procedure might have more long term complications and nutritional supplements are needed for life. |
Very safe. It must be used with extremely obese patients
(BMI>55).
Appropriate for patients with BMI between 35-45 because of the low operational risk.
Must control sweets and snacks. |
Requires more effort by the patient.
Appropriate for patients who want to participate in a program to change eating habits, with dietetic restrictions and physical exercise for life!!. |
