Duodenal Switch
The “modified duodenal switch” (ModDS) has become a less invasive weight loss surgery option for many patients. Instead of two connections as in the gastric bypass or the more traditional duodenal switch, a single connection is made. This allows the surgery to be performed more quickly and with less risk of leaks, thereby decreasing the risk of surgery.
With this surgery, the stomach is reduced in size, which restricts the amount of food that one can eat and the number of nutrients that your body absorbs is reduced by bypassing a portion of the small intestine.
At two years after the ModDS, patients can lose greater than 95% of their excess weight and more than 90% achieved complete remission of diabetes.
Gastric Bypass
The gastric bypass, also known as the laparoscopic Roux-en-Y, leads to weight loss through two mechanisms: restriction and malabsorption.
The restriction is done by reducing the size of the stomach, which limits the amount of food you can eat before you feel full. Malabsorption occurs as a portion of the small intestine is bypassed, reducing the amount of food the body will absorb. At Roller Weight Loss, we perform this procedure laparoscopically 99% of the time, aiming to avoid creating a large incision in the abdomen.
This operation is considered the gold standard for weight loss surgery and patients generally lose between 65% to 80%* of their excess weight.
Gastric Sleeve
The laparoscopic sleeve gastrectomy (Gastric Sleeve) leads to weight loss by reducing the size of the stomach, making you feel full after eating only small portions. Approximately 75% of the stomach is removed, leaving behind a smaller, tube-shaped stomach (or “sleeve”).
The portion of the stomach that makes the hormone ghrelin, which is responsible for making us feel hungry, is removed. Additional hormones responsible for the feeling of hunger eventually take over.
Advantages of this procedure include no implantation of an artificial device, no re-routing of the intestinal tract, and less frequent follow-up compared to other weight loss surgery.
