ROUX-EN-Y GASTRIC BYPASS SURGERY uses a combination of restriction and malabsorption. During the procedure, the surgeon creates a smaller stomach pouch. The surgeon then attaches a Y-shaped section of the small intestine directly to the pouch. This allows food to bypass a portion of the small intestine which absorbs calories and nutrients. Having the smaller stomach pouch causes patients to feel full sooner and eat less food. Bypassing a portion of the small intestine means the patient's body absorbs fewer calories. This is still the most common type of weight-loss surgery performed in the United States. It is still considered the "Gold Standard" in weight loss surgery.
LAPAROSCOPIC ADJUSTABLE GASTRIC BANDING is a restrictive procedure. Two medical devices are implanted in the patient: a silicone band and an injection port. The silicone band is placed around the upper part of the stomach and molds the stomach into two connected chambers. The injection port is attached to the abdominal wall, underneath the skin. The port is connected to the band with soft, thin tubing. The banding is adjustable. Inflating the balloon inside the band with the saline solution further restricts the opening through which food passes. This reduces the amount of food you can eat at one time and also slows the passage of food. This should also help the patient feel full longer as food takes longer to pass through the band.
LAPAROSCOPIC SLEEVE GASTRECTOMY is a restrictive procedure which limits the amount of food you can eat by reducing the size of your stomach. During this procedure, a thin vertical sleeve of stomach is created using a stapling device. This sleeve will typically hold between 50 to 150 ml, about the size of a banana. The excised portion of the stomach is removed. This surgery reduces the amount of food you can eat and gives you a prolonged sense of fullness.
