Weight loss surgical procedures are designed to physically alter the stomach to make a smaller upper pouch and a larger lower pouch. The creation of the very small upper pouch limits the amount of food that can be eaten. Additionally, the small intestine is then attached to both pouches. There are different ways to complete this procedure, with each of the gastric bypass procedures offering various benefits and potential complications based on the patient.
In Dallas weight loss centers, the doctor will discuss the different bypass surgeries possible and recommend a specific procedure. It is very common for patients to have a good understanding of the different options in gastric bypass procedures before this meeting, which is helpful in asking questions and getting clarification.
To understand the possible options for this bariatric surgical procedure, here the most often recommended variations and their differences.
- Roux en-Y (RYGB, proximal) –this creates a Y-shape with the small intestine to allow both the small and large pouch to drain. The Y-shape is created at the top end of the small intestine, which is why it is termed “proximal.” This preserves the greatest amount of small intestine for nutrient absorption.
- Roux en-Y (RYGB, distal) – similar to the procedure mentioned above, but the Y is formed in the small intestine further down or in a more distal location. As there is less absorption that takes place in the small intestine, there can be more rapid weight loss for patients. However, there is also less absorption of essential minerals and fat-soluble vitamins, which results in the patient having to compensate with supplements and dietary measures.
- Mini-gastric bypass – this procedure creates a tube that runs along the right border of the stomach. A loop of the small gut is then connected to the tube. This is an easier procedure with less risk of complications and offers effective, sustained weight loss.
Choosing the correct form of gastric bypass surgery is an important decision. Take the time and understand the options as well as the possible complications and talk to your doctor in Dallas about any concerns or questions you may have.
