How Biliopancreatic Diversion with Duodenal Switch (BPS/DS) is Done 


Are you suffering from obesity and failing to lose weight with traditional methods? Bariatric surgeries are the last resorts that help you lose weight and prevent obesity complications. 

Biliopancreatic diversion with duodenal switch is one of the most effective weight loss surgeries because it is designed for rapid weight loss in people who suffer from severe obesity. It’s a combination of sleeve gastrectomy with an intestinal bypass. It is amazingly effective against type 2 diabetes and other obesity-related conditions. However, it is a complicated surgery that involves risks as well. Log on to to know more about weight loss.

Before the surgery, you need to take several screening tests to check that your condition is good for the surgery. Then, you need to make changes in your diet and start several exercises to make yourself fit for the surgery. Let your bariatric surgeon know about the medication you’re taking such as prescribed drugs or over-the-counter medications so that the doctor can tell whether you need to stop taking certain medicines and reduce their dose before surgery. Because certain medications can lead to complications (such as blood thinners can cause blood clotting or bleeding), that’s why they are not recommended during the surgery. Other than that, if you smoke or drink alcohol, you need to quit before the surgery. 

Before the operation, the doctor gives you anesthesia to make you fall asleep so that you don’t feel pain during the surgery. This surgery is done by open, or laparoscopic methods. Usually, the most common choice is the laparoscopic method because it is less invasive, and surgeons use narrow tools through small keyhole incisions instead of opening your abdominal cavity. This method reduces the risk of complications. 

This surgery is done in two steps process: 

First step:  

The first step starts with removing a portion of the stomach. Surgeons make incisions with open or laparoscopic technique, remove a substantial portion of your stomach, and attach the remaining portion into a narrow sleeve, which is your new stomach. Your surgeon doesn’t make any changes to the tube which sends food through the stomach into your small intestine, along with the small portion of the small intestine that connects to your stomach.  

Second step:  

Now, in the second step, your surgeon bypasses your small intestine around the top section (which is called the duodenum). Then, your surgeon brings the lower section of your small intestine up to the top to attach and bypass the middle. This way, your duodenum is switched from the lower part of your small intestine.  

If you get the original duodenal bypass (Biliopancreatic diversion) then it removes 80 to 90% of the area which drastically reduces the nutrition absorbed from the food, leading to significant weight loss but with an increased risk of malnutrition. Whereas the modified version of the duodenal switch involves the removal of around 50 to 60% which reduces the risk of malnutrition. The original version reconnects your small intestine at two separate places and on the other hand, a modified version made only one division and reconnection.  

Usually, BPS/DS takes several hours. You will wake up in the recovery room where medical staff monitors you to make sure that you didn’t have any complications.
