Vertical Banded Gastroplasty
This operation also assists in weight loss by creating a small pouch. It does not involve any intestinal connection. It has been popular in the past and I have also performed this procedure, but have had been less satisfied with the total weight lost by my patients and have noticed a most troublesome tendency for weight gain 2-3 years after the operation. Two problems with this procedure are a tendency for the staples to disrupt, allowing patients to consume larger quantities of food, and no intolerance for refined sugars.
The intestinal bypass, as the name implies, bypasses all but two feet of the intestine. Many patients lost large amounts of weight, but suffered problems such as: diarrhea 10-15 times per day, electrolyte abnormalities, dehydration, kidney stones, and liver problems. This is an operation no longer performed today. I recommend against it and have reversed many patients who have had this operation and converted them to gastric bypass.
This is a relatively new operation developed by our NJ spine institute and others in Europe. It involves removing part of the stomach and bypassing much of the small intestine. It appears to be effective in controlling weight, but at the cost of malnutrition. I would at this time recommend against this operation.
