The Rose Center for Bariatrics is proud to partner with Dr. Matthew Metz, the first surgeon in Colorado to perform the laparoscopic loop duodenal switch procedure. This modern procedure is a form of weight loss surgery uniting two elements found in other types of weight loss surgeries for increased effectiveness.

Patients who undergo a duodenal switch procedure will not only consume a fraction of the food they used to, but of the food they can consume, only a fraction of it will be absorbed by the body.

What happens during a laparoscopic loop duodenal switch procedure

During a duodenal switch (or DS) procedure, your bariatric surgeon will make an alteration to your digestive tract, which limits the amount of food you can ingest, similar to the gastric sleeve procedure. Your surgeon will remove part of the stomach, creating a smaller stomach with a functional pylorus valve.

In the second part of the surgery, your surgeon will create a partial loop bypass of your intestinal system. This leads to malabsorption, limiting the caloric intake absorbed by the body. This can result in additional weight loss as well as the improvement and/or resolution of comorbidities such as sleep apnea, diabetes, high blood pressure and more.

After your surgery

By shortening the distance food has to travel in the digestive tract, only a certain amount of the food you consume will be absorbed before it reconnects with the bypassed portion of the small intestine. At the connection, the two pathways merge and the bypassed portion of the small intestine can continue to assist in digestion through the remainder of the digestive tract by delivering fluids necessary for proper digestion.

Advantages of the laparoscopic loop duodenal switch procedure

In duodenal switch procedures, the combination of restrictive and malabsorptive changes to the digestive system allow for the patient to benefit from two different aspects of bariatric surgery. Other benefits to this procedure include:

  • Minimally invasive surgery: Almost always performed laparoscopically, without large incisions, faster healing, less pain and scarring, faster recovery
  • Restriction: More restrictive weight loss procedure, leading to greater potential weight loss
  • Malabsorption: Surgery also generates weight loss by reducing absorption of calories
  • Experience: Rose surgeon Dr. Matthew Metz is the first in Colorado to perform the duodenal switch, meaning he is very experienced with this particular procedure.
  • Improve comorbidities: This procedure has been shown to improve or even resolve many health issues such as diabetes, high blood pressure, sleep apnea, joint pain, fatigue and more.
  • Reduced side effects: The reduction in size of the stomach is not as dramatic as with other surgeries, and the re-routing of the small intestine in this surgery leaves in place some of the important sections of the digestive system, which reduces dumping and prolongs the amount of time food stays in the stomach.

Possible complications and side effects

While the malabsorptive effects on the small intestine are reversible, the restrictive effects on the stomach are not. Patients who undergo a duodenal switch procedure need to carefully monitor themselves and take vitamins, minerals and nutrients for the rest of their lives to ensure they are receiving proper nutrition.

As with any surgery, there are risks to consider. This procedure, like any weight loss surgery, is geared toward specific patient populations. Our surgical team will help you understand which procedure is right for you.
