*This surgery is not recommended for all patients

The procedure

Intestines that are adjusted during duodenal switch surgery.The Duodenal Switch Surgery is a very effective form of bariatric surgery available for super obese patients. This revolutionary surgical procedure may help extremely overweight patients lose weight in a short period of time and keep it off. The duodenal switch surgery is definitely not right for every patient however, and Dr. Hidalgo can evaluate if it is right for you.

The incisions

Incisions necessary to perform duodenal switch surgery.During duodenal switch surgery, Dr. Juan Francisco Hidalgo performs a partial gastrectomy to reduce the size of the stomach. The resection is created along the elongated side of the stomach to restrict the stomach’s capacity to hold food. The normal functionality of the organ isn’t compromised; rather, only its size is reduced. Unlike other gastric bypass procedures, the pyloric valve and the duodenum will remain intact. The preservation of the pathways will allow food to pass through the stomach and intestines with ease, and your body will be able to absorb a healthy amount of nutrients throughout the digestive process. Additionally, during duodenal switch surgery, Dr. Hidalgo will rearrange the layout of the small intestine to differentiate the flow of food from the flow of stomach bile and pancreatic juices. By adjusting your small intestine, he can restrict your caloric intake while your food breaks down in your digestive track. Fat absorption will be limited throughout the process as your food makes its way into the large intestine.

The patient should be super obese with BMI of over 70 to even consider this procedure.





This surgery takes about 2 to 3 hours. The patient should lose up to 80% of their excess weight.
