Biliopancreatic Diversion With Duodenal Switch

On this page, you will learn more about biliopancreatic diversion with duodenal switch surgery; what it is, and how it works. You will also learn about the potential complications and benefits this type of procedure offers you for weight loss.

Most commonly referred to as the duodenal switch, this procedure is performed less commonly. It is better suited for patients with a high BMI with multiple medical problems.

How Does Duodenal Switch Surgery Work?

Our NYC and NJ duodenal switch procedure is done robotically through several small incisions. This procedure is performed in one stage or two stages depending on patient circumstances. Duodenal switch has restrictive and malabsorptive components that work simultaneously to help you lose significant weight. This rapid weight loss helps with the resolution of many of the diseases that come about due to morbid obesity: diabetes mellitus, high cholesterol, and high blood pressure.

The first portion of the procedure involves creating a sleeve just as is done in the sleeve gastrectomy. We remove 70-80% of your stomach. The portion of the stomach that is removed is the area that makes a hormone called Ghrelin. Ghrelin is the hormone that stimulates feelings of hunger. The surgery also reduces the volume of your stomach, making you feel full more rapidly.

The second portion of the procedure involves rerouting the small intestine. This portion of the procedure is the malabsorptive part. Unlike in gastric bypass, this rerouting connects the last part of the small intestine to the first part of the small intestine just off the stomach. Rerouting or bypassing the small intestine means that small intestine is not removed, but changed in position- this change means you absorb less of the food you eat.

The average length of small intestine in an adult is 20 ft or 610 cm. In the duodenal switch you are only going to absorb your food normally in the last 100 cm of small intestine. With less small intestine to absorb food, you absorb less calories but are at higher risk of malnutrition, dehydration, and problems due to insufficient absorption of vitamins and minerals.

All forms of gastric and intestinal surgery carry risk, and this procedure does carry a slightly higher risk. Patients selected to undergo duodenal switch are carefully selected and prepared.


Advantages Of The Duodenal Switch Surgery

The restrictive component of this operation (sleeve gastrectomy) significantly reduces your Ghrelin levels so your feelings of hunger will decrease after the operation. Restriction also decreases the volume of the stomach so you will also feel full faster and will not be hungry eating less food.

The malabsorptive component of this operation allows fewer calories to be absorbed- as a result higher and more sustained weight loss occurs. Malabsorption improves your pattern of insulin secretion which results in a 95% reduction of type 2 diabetes. Malaborption produces a significant decrease in LDL cholesterol (the bad cholesterol).

DuoDenal Switch FAQ

Those who are considering undergoing weight loss surgery have many questions and concerns. We have offered some basic information about the duodenal switch, and answers to some of the most common questions patients we are asked about the procedure.

Is the duodenal switch procedure better than gastric bypass surgery?

The duodenal switch and gastric bypass both have restrictive and malabsorptive components in which new connection between the stomach and small intestine is surgically created. The duodenal switch has a higher level of malabsorption. This malabsorption leads to a higher level of weight loss (85% of excess weight lost) and better sustainability of the weight loss. This procedure is ideal for patients with and high BMI and other medical issues related to obesity.

Will I maintain the weight loss after a duodenal switch surgery?

Research has shown that patients undergoing this surgery lose about 85 percent of their excess weight, on average. Additional weight can be lost if you carefully watch your diet and engage in a regular exercise program.

You will have lost a significant quantity of weight, very quickly, and will then “plateau.” Making it through this period is one of the most critical points in maintaining weight loss. You may to add more exercise to your weight loss regimen (such as a walk) to continue to lose. What you consume makes a difference – it is advised that you track what you consume and avoid sugary, fatty foods as a lifestyle change. One of the challenges you may face is not falling back into unhealthy eating habits.

How much weight will I lose with a duodenal switch?

Most patients are reported to lose about 85 percent of the excess weight. Even with such a dramatic loss of weight many people want to lose even more, which can be accomplished without much difficulty by following a strict exercise and diet plan.

How long will I need to recover from a duodenal switch?

Most patients can return home the day following surgery. The most important issue in being released to go home is the ability to stay hydrated. You will be able to walk just a few hours after surgery and will start the first stage of the recovery diet with clear liquids. Any pain can be managed with prescription medication during this phase. Initially, you will feel very tired and will want to rest. Depending upon your general health, you will be ready to go back to work within one to three weeks for most patients. Everyone heals at a different rate.

Is the duodenal switch for me?

If your body mass index, BMI, is greater than 50 and you have diabetes mellitus you are strong candidate for the duodenal switch. You do need to be committed to keeping up with the daily protein requirement which can be done with food and protein shakes. You must take additional bariatric vitamins and supplements outside of a multivitamin for the rest of your life.
