Weight loss from bariatric surgery typically works by either restricting food intake, restricting absorption or a combination of both. Duodenal switch surgery procedures combine both absorption restriction and food restriction techniques by rearranging the intestines resulting in less calorie absorption and decreasing stomach capacity thereby restricting food intake. This procedure may be referred to as Laparoscopic Sleeve Gastrectomy with Duodenal Switch, or Biliopancreatic Diversion with Duodenal Switch. It may also be referred to as the BPD/DS, the “Duodenal Switch”, the “DS”, or the “Switch”.
Patients and surgeons have reported these advantages with duodenal switch procedures:
- Long term weight loss is quicker, and the weight loss is sustained
- A lower chance of regaining weight over time
- The “relatively” conservative nature of the surgery (when compared with other weight loss surgeries) results in more normal eating habits over time
Also, studies show that obesity-related conditions are resolved more completely with the duodenal switch procedure. Patient experience with duodenal switch surgery has resulted in the loss of fifty percent of excess body weight in about six months and up to ninety percent of excess weight during the first two years after surgery according to industry sources.
Anaheim duodenal switch surgery can be performed either laparoscopically or via other surgical procedures. Laparoscopic approaches may result in fewer surgical complications and is a newer innovation in the field of duodenal switch surgeries.
To achieve stomach restriction, the stomach is reconfigured into a smaller shape that holds less food than before, but holds more food than with other weight loss surgery procedures such as Lap Band.™ The advantage to this is that it allows a more normal eating regimen while still restricting the size of the stomach. It also preserves the first part of the small intestine that is responsible for mineral absorption.
The second component of this surgery, restricting the absorption of calories, results from the reconfiguration of the small intestine. Shortening the intestines means less fat is absorbed, and fewer calories are absorbed into your system.
Doctors and patients may elect the duodenal switch over a gastric bypass because it results in a more natural small intestine and stomach arrangement. In some cases, the intestinal part of the surgery may be reversed in the future if required.
