The Truth About Having Duodenal Switch Surgery

Duodenal switch surgery – also known as biliopancreatic diversion with duodenal switch – is the least commonly performed bariatric surgery procedure available. The procedure itself is both restrictive and malabsorptive. This means that although it’s effective at causing weight loss, it’s also more complicated than other surgeries which purely focus on the restrictive aspect. As a result, it’s generally only used when another, less invasive procedures have failed. Read on to learn:

  • What the surgery entails, how it works, and the permanency of the procedure
  • The risks of the procedure
  • The recovery process
  • The dietary restrictions after the surgery
  • How quickly to expect weight loss after surgery

What is Duodenal Switch and How Does the Procedure Work?

A duodenal switch involves a two-part procedure; one that creates the restrictive component of the weight loss and the other to promote malabsorptive weight loss.

  1. Restrictive – The restrictive part of the procedure involves reducing the size of the stomach by around 80 to 85 percent. This is basically the same as a gastric sleeve procedure, which means the majority of your stomach is permanently removed and you will be left with a “sleeve,” or small, banana-shaped stomach.
  2. Malabsorptive – The malabsorptive portion of the procedure involves the actual duodenal switch. To do so, your surgeon will re-arrange your small intestine to separate food from bile and pancreatic juices. The food and digestive juices will only come into contact in the last 18 to 24 inches of the intestine, which promotes malabsorption (and hence, weight loss). This means that duodenal switch surgery keeps your small intestine intact, as well as the pyloric valve that regulates the release of food into the small intestine.

Biliopancreatic Diversion

While the restrictive portion of duodenal switch surgery is permanent, the duodenal switch can actually be reversed, at least in part. Thus, if you experience any complications following the procedure and do not want to continue it long-term, you may have the option to have this part reversed.

Typically, due to the complex nature and potential complications of the duodenal switch procedure, it’s reserved for individuals who need to lose a substantial amount of weight, or those who are suffering from a serious, weight-related condition.

The procedure itself is extremely effective and has been known to reverse conditions such as type 2 diabetes, hypertension, and even sleep apnea. As a result, those who have a body mass index (BMI) greater than 40 or are suffering from an illness such as diabetes are great candidates for this procedure.

Some studies have revealed that duodenal switches are more effective for older individuals who have a lot of weight to lose when compared to those who opt for the Roux-en-Y gastric bypass, instead.

The risks of having Duodenal Switch surgery

Complications can arise during duodenal switch surgery, immediately afterwards or even several months or years later. It’s important you consider these risks before deciding to take such a drastic step to reduce your weight.

During the operation, several complications can arise, including:

  • Excessive bleeding
  • Injury to surrounding organs
  • Cardiovascular complications, including an increased risk of suffering a heart attack

Following the operation, other risks can arise, including:

  • Infection
  • Abscess formation around the incisions
  • Bleeding
  • Blood clots
  • Bowel obstruction
  • Leaking in the small bowel, duodenum, or stomach
  • Pancreatitis
  • Pneumonia
  • Cardiovascular conditions, such as a heart attack

Long-term issues are generally related to other common problems with malabsorptive weight-loss procedures, including:

  • Hernias
  • Malnutrition, including vitamin and mineral deficiencies and anemia
  • Kidney stones
  • Osteoporosis
  • Diarrhea
  • Foul bowel movements and gas
  • Bowel obstruction

The Recovery Process

Unlike other bariatric surgery procedures that generally only last around an hour, having duodenal switch surgery can take up to four hours. To reduce the length of the operation, some surgeons even choose to break the surgery up into different parts. However, a full recovery is generally possible no more than 6 weeks following the procedure, which is roughly similar to that of both gastric bypass and gastric sleeve surgery.

Generally speaking, patients remain in the hospital for up to three days following the procedure. This relatively short stay is thanks to the surgery being performed laparoscopically, meaning there are no major incisions.

Duodenal Switch diet

Your diet will change from week to week during the first month of recovery as follows:

  • Week 1 – During the first week, you’ll be on a clear liquid diet. This means you can drink water, and broth, and should do so in small quantities to accommodate the size of your new stomach
  • Week 2 – You can begin to add pureed foods and other drinks, like protein shakes, into your diet during week 2. You should keep your diet as plain as possible during this time. blended soups, applesauce (with no sugar added), and skim milk are good choices.
  • Week 3 – You should continue with the pureed foods, but may start to add soft, solid foods as well! Some good examples include fish, eggs, lean ground meats, soft fruits, cooked vegetables, and beans.
  • Week 4 – Week 4 is when you can begin to get back to eating ‘normal’ foods. During this week, you can begin testing solid foods, but they should be ‘whole’, not processed. Chew slowly, and well, to make it easier for your body to digest. Most importantly, keep your meals simple so you can see what your new stomach can handle before pushing it too far.

How Soon to Expect Weight Loss

As is the case with all weight loss surgeries, the more you stick to a healthy diet and exercise routine, the better your results will be. For example, you should exercise at least three to four days per week, for about 30 to 45 minutes per day. And, you should always be aware of what, and how much, you’re eating. Even with restrictive surgeries, you can stretch the stomach out if you’re eating too much, quickly undoing the benefits of the procedure.

Duodenal switch surgery is a great option for those who need to lose a significant amount of weight and have few, if any, other options. Due to the complex nature of the procedure, as well as its relative permanency, it’s important to discuss this option and others with your doctor before making any decisions.

A less invasive, but effective alternative

We all know that diet and exercise alone doesn’t work for everyone. Some people genuinely struggle to control their appetite and urge to overeat.

Although those people may turn to ‘last resort’ options such as duodenal switch surgery, it may be worth testing your body’s response to a comprehensive dietary supplement such as PhenQ first.

PhenQ works by both suppressing your appetite and increasing the amount of stored fat you burn. It does this using completely safe, natural ingredients and is well worth a try before you resort to risking the complications of duodenal switch surgery.
