Weight loss surgeons on the medical staff of Baylor Dallas have performed more than 8,000 weight loss procedures since the program began more than a decade ago. A majority of the procedures are performed laparoscopically, often on an outpatient basis.
When you meet with a physician on the medical staff at Baylor Dallas you will discuss options and determine the procedure that is most appropriate for you.

Bariatric surgery changes the size of your stomach and the length of your small intestine that comes in contact with the food you eat. The goal is to limit how much food can be eaten and/or absorbed at one time. Bariatric surgery can be done in several ways. You are having a Roux-en-Y Gastric Bypass (RYGB). This is the most common type of bariatric surgery. During this type of procedure, part of the stomach is separated from the rest of the stomach and closed off with staples to create a smaller pouch. The smaller stomach helps restrict the amount of food you can eat at one time. The small intestine is then divided, and part of it is reattached to the stomach pouch. Because some of the small intestine is bypassed, less food is absorbed as well.
A large portion of the stomach is closed off. This leaves a small pouch to hold food, restricting the amount that can be eaten at one time. The small intestine is cut below the duodenum and reattached to the new stomach pouch. This leaves a shortened path for food to travel through. As a result, some of the food that is eaten is expelled as waste and not absorbed as energy. The remaining pouch of the stomach and duodenum are also reattached to the small intestine farther down to drain stomach, biliary and pancreatic enzymes, and fluids.
Bariatric surgery is designed to cause a large amount of weight loss. Weight loss can cause deposits in the gallbladder called gallstones. The gallbladder may need to be removed at a later date. If you already have gallstones, the gallbladder may be removed at the time of your RYGB operation.
All types of bariatric surgery have different advantages and disadvantages. Be sure to discuss the risks and complications of this surgery with your healthcare provider.
During gastric bypass procedures, the stomach size is reduced to limit the amount of food it can hold. As a result, you eat less food and lose weight.
Bariatric surgery is a procedure that helps you lose weight. During vertical sleeve gastrectomy, approximately 80% of the stomach is removed. The part of the stomach that is removed is thinner than the rest of the stomach and stretches out when you eat to hold all the food. The part of the stomach that is not removed is a narrow "sleeve." This sleeve does not stretch very much and can hold only a few tablespoons of food. Food passes slowly through a narrow opening at the bottom of the stomach called the pyloric valve, and food empties out like it does before surgery.This procedure produces changes in hormones that reduce appetite. In the sleeve gastrectomy, the surgery is only on the stomach and is not on the small bowel.
This surgery can be done using one or two approaches:
For laparoscopic surgery, small incisions are made in your upper stomach. During the procedure, a tiny camera sending images to a monitor and thin surgical instruments are inserted through these small incisions. The surgeon operates by looking at the organs on a video monitor. Almost all sleeve gastrectomy procedures are now done laparoscopically.
For open surgery (also called laparotomy), one larger incision is made in the middle of the upper stomach. The surgeon sees and works through this incision. Most cases are not done this way because the laparoscopic approach, if possible, involves smaller cuts, less tissue damage, and fewer problems.
Using either type of approach, the stomach is cut lengthwise (up and down) with a stapling instrument. The larger part of the stomach is removed. The side of the remaining stomach (the sleeve) is closed off with staples made out of titanium.
This creates a narrower, smaller-volume stomach in the shape of a banana, or a sleeve.
Bariatric surgery is designed to cause a large amount of weight loss. Weight loss can cause gallstones. If you already have gallstones, the gallbladder may be removed during your surgery or at a later date to prevent gallbladder problems from developing.
By removing part of the stomach, not only is stomach volume decreased, but the part of the stomach that is removed also decreases appetite.
Weight-loss (bariatric) surgery changes the size of your stomach to help you lose weight. The surgery may also keep your body from absorbing nutrients. The goal is to limit how much food can be eaten or absorbed at one time, or both. There are several types of weight-loss surgery. You are having laparoscopic adjustable gastric banding. This surgery closes off part of your stomach to make a very small pouch. This is the most common type of weight-loss surgery that restricts how much food you can eat.
The surgeon puts an adjustable band around the top part of your stomach. The band is like a ring. It makes a small pouch in your upper stomach. This pouch holds only a few tablespoons of food. Food passes slowly through a narrow opening at the bottom of the pouch. This lets you feel full longer. The size of the band can be changed by using a port placed under the skin. The port gives your healthcare provider a way to put in a needle. He or she uses the needle to add or remove fluid from the band. This is done to make the size of the opening bigger or smaller. Changing the band changes how quickly food leaves the new pouch.
Weight-loss surgery is meant to cause a large amount of weight loss. Weight loss can cause gallstones. These are collections of solid material in the gallbladder. These collections could potentially cause blockage, inflammation, and pain. To prevent this, the surgeon may remove the gallbladder during your surgery if you already have gallstones. Or you may need your gallbladder removed at a later date.
All types of weight-loss surgery have different advantages and disadvantages. Be sure to discuss the risks and complications of this surgery with your healthcare provider.
Also known as Lap-Band®, the stomach is wrapped with an adjustable silicone band, which can be tightened or loosened to control stomach size.
Bariatric surgery can be done in several ways. This type of bariatric surgery changes the size of your stomach and the length of your small intestine. The goal is to limit how much food can be eaten and absorbed at one time. During this type of procedure, part of the stomach is closed off with staples to create a smaller pouch. The remainder of the stomach is removed. This smaller stomach restricts the amount of food you can eat at one time. The small intestine is then divided, and only a very short length of its lower portion is reattached to the stomach pouch. Because part or most of the small intestine is bypassed, less food is absorbed.
Only a very short length of intestine is left that can absorb food. As a result, most of the food that is eaten is expelled as waste and not absorbed as energy. This can lead to nutritional deficiencies.
Bariatric surgery is designed to cause a large amount of weight loss. Weight loss can cause deposits in the gallbladder called gallstones. The gallbladder may be removed during your surgery if you already have gallstones. Or it may need to be removed at a later date if you develop gallstones.
Biliopancreatic diversion surgery with duodenal switch changes the size of the stomach and the length of the small intestine to limit how much food can be eaten and absorbed at one time.
Roux-en-Y gastric bypass and adjustable banding procedures may be reversed through revisional surgery if results are unsatisfactory or other issues indicate need for a reversal.
