What is the Duodenal Switch Procedure?
Duodenal switch is an alternative surgery to the more common gastric bypass surgery and one that you might consider as you search for solutions to losing weight.
The single-anastomosis loop duodenal switch is a modification to the sleeve gastrectomy, increasing its weight loss effectiveness and resolution of diabetes. It is a more complicated procedure than other bariatric surgeries because it combines both the restrictive and malabsorptive components of gastric bypass and gastric sleeve procedures. During the procedure, the surgeon permanently removes the stretchy outer and upper 70-85 percent of the stomach; leaving a tubular-shaped stomach with a 5-6 ounce capacity. The small intestine is then rearranged just beyond the stomach, thus changing the absorption of nutrients. With the duodenal switch, weight loss is achieved both through restriction of food consumption as well as malabsorption. The restrictive component involves reducing the size of the stomach, which drastically reduces food consumption during each meal. The malabsorptive component involves rearranging the small intestine to separate the flow of food from the flow of bile and pancreatic juices. This restricts the number of calories and nutrients the body absorbs.
Duodenal switch is reserved for the most severely obese patients who are suffering from serious related medical issues. As a combination of gastric bypass and gastric sleeve, it works in two parts: first, a smaller, tubular pouch is created by removing a portion of the stomach, similar to the sleeve gastrectomy; second, a large portion of the small intestine is bypassed. Since the stomach is shrunk and only a small portion of the intestine has a chance to digest food before it enters the colon, this procedure offers both restrictions (eating less because you feel full more quickly) with malabsorption of fat to give you a very powerful bariatric surgery procedure.
Duodenal Switch is considered the best option for patients with a BMI greater than 50 who wish to improve obesity-related health problems. The average amount of excess weight loss after the procedure is approximately 70% according to statistics. Duodenal Switch provides the highest number of weight loss. The operation is recommended for patients that have a large amount of weight to lose, i.e., 100lb or more. This option is also recommended for patients who are diabetic as the Duodenal Switch better resolves diabetes than other options available. In addition, this option is available for patients that did not have luck with Gastric Bypass surgery or feel that their weight loss was insufficient.
