Duodenal Switch Surgery Houston

The duodenal switch—also known as the biliopancreatic diversion with duodenal switch—is a bariatric surgical procedure with some similarity to the gastric bypass. The surgery streamlines the stomach and its intersection with the upper small intestine, called the duodenum. By reducing the size of the duodenal switch, the procedure inhibits a patient’s appetite.

Texas Endosurgery is the ultimate destination for weight loss solutions. If you struggle with hunger issues and the resulting weight gain it creates, consider the benefits of duodenal switch surgery.

About Weight Loss Surgery

When most people think of bariatric surgery, they immediately conjure up a gastric bypass procedure. Gastric bypass surgery works by creating a small pouch and connecting the small intestine to this truncated stomach cavity.

Duodenal switch works differently. Instead of a small pouch attached to the Y section of the small intestine, the duodenal switch surgeon actually creates a sleeve, or a sleeve-shaped stomach. Afterwards, the final section of the small intestine is attached to the stomach sleeve. So, the procedure bypasses all but the last section of the small intestine, which allows your body to reduce the amount of calories and fat it absorbs. This allows recipients a greater capacity to eat compared to other bariatric procedures, but fatty foods can carry potential concerns.

Duodenal Switch vs. Gastric Bypass

Both gastric bypass and duodenal switch are potentially effective ways to reduce excess weight when paired with a healthy diet and exercise. Many patients enquire about the difference between the two. Ultimately, the goal of both procedures is to reduce weight. They just go about achieving weight loss in distinctly different ways. 

Gastric bypass reroutes the majority of digested food through a “Y” shaped intersection. Duodenal switch surgery, on the other hand, consists of two distinct steps. First, approximately 80% of the stomach is removed. The remaining material is fashioned into a sleeve formation, like the contours of a banana. The junction with the duodenum is left intact, but the entire mechanism is streamlined to help reduce a patient’s appetite.

Next, Dr. Bonnor truncates the small intestine. He accomplishes this goal by making one incision close to the upper duodenum and another toward the end of the small intestine. Your surgeon joins these two portions of the small intestine, creating a harmonious system that is perfectly equipped to process the reduced caloric intake that a duodenal switch procedure facilitates.

Benefits of Biliopancreatic Diversion

The duodenal switch procedure offers a plethora of benefits for patients seeking to reduce their excess weight. The surgery preserves the pylorus, which is the passageway between the stomach and the upper small intestine (duodenum). Due to the preservation of the duodenal junction, patients do not experience the same “dumping syndrome” associated with other bariatric procedures. Dumping syndrome refers to the rapid movement of food through the digestive system that may trigger sweating, nausea, diarrhea and other distressing phenomena.

Eligible Candidates

If you have a body mass index (BMI) of 35 or higher, you may be an ideal candidate for duodenal switch treatment. Please tell your Texas Endosurgery representative about your general  nutrition so they can determine the best course of action for your case. 

The duodenal switch procedure limits your intake of food, so it is important that you create a post-surgery diet plan to ensure proper nutrition. Call (281) 579-5638 to begin a conversation with the health care team that can unleash the slim, striking new you.

Preparation and Procedure

Duodenal Switch Surgery Houston

During your comprehensive consultation, you will receive detailed instructions to prepare you for biliopancreatic diversion with duodenal switch (BPD/DS). These directions are customized to your needs, diet, and lifestyle. Please follow them closely.

In general, you should quit smoking at least three weeks before any invasive procedure. You should also stop taking certain blood thinners such as aspirin and ibuprofen. Dr. Bonnor and his associates will prescribe a strict diet in the days leading up to your surgery. 

On the day of your procedure, you will meet with your surgeon to review the particulars of your duodenal switch surgery. An anesthesiologist will administer the appropriate sedative to keep you safe and comfortable throughout the procedure. 

Dr. Bonnor will begin by surgically reducing the size of your stomach and contouring it to be more streamlined. Next, your small intestines will be bypassed to connect the lower portion directly to the duodenal junction. The duration of a BPD/DS procedure varies from patient to patient. Texas Endosurgery will focus our full array of resources and expertise to your treatment, ensuring you get the best care imaginable. 

Healthy Recovery

Immediately following duodenal switch surgery, a medical professional will monitor your progress. Once you are deemed ready to return home for a restful recovery, you will be released to your caregiver.

Your diet will consist of liquids for the first 1-2 days after the duodenal switch procedure. You can gradually incorporate pureed foods into your routine, according to the timetable Dr. Bonnor advises. 

When your body is ready to digest solid foods, you can introduce them to your diet slowly and cautiously. Your hunger will be greatly reduced following surgery, so it is essential to pay attention to what your body needs. Dr. Bonnor will recommend a multivitamin to supplement your nutrition. It is especially important to bolster your intake of calcium and vitamin B12.
