Laparoscopic Sleeve Gastrectomy with Duodenal Switch
What is the Laparoscopic Sleeve Gastrectomy with Duodenal Switch?
The laparoscopic sleeve gastrectomy with duodenal switch combines two bariatric surgeries. First, a sleeve gastrectomy wil be peformed. The new pouch, referred to as the "sleeve", can hold between 3-5 ounces. This restricts the amount of food that can be eaten at any one time and reduces hunger. Next, the small bowel is rearranged, bypassing a significant portion of the small bowel, which results in malabsorption. This is referred to as the "duodenal switch" portion of the surgery.
The laparoscopic sleeve gastrectomy with duodenal switch results in a dramatic weight loss of 80-85% of excess body weight. This surgery is especially good for people who have a great deal of weight to lose or have significant comorbid conditions requiring quicker resolution.
What are the health benefits of Sleeve Gastrectomy with Duodenal Switch surgery?
Most individuals experience additional health benefits from gastric sleeve surgery. In 95% of patients the quality of life improved and obesity-related health conditions (called "comorbidities") were resolved or improved. In addition mobility and energy are usually greatly improved.
- Rapid and large weight loss
- Quicker resolution of comorbid conditions related to obesity
- Increased chance of sustained weight loss
- Patients do not experience dumping syndrome, common with Roux-en-Y gastric bypass surgery, because the pyloric valve between the stomach and small intestine is kept intact
- Higher risk of nutritional deficiencies requiring careful monitoring and continued supplementation with vitamins and minerals
- Possibility of significant food intolerances especially to sugar and fat.
- Malabsorption procedures have a period of intestinal adaptation causing frequent and very soft bowel movements (4-6 per day), which may or may not lessen over time
- May cause gas pains, bloating, frequent passing of very smelly gas
