Our Bariatrics Center offers several options for patients who qualify for weight-loss surgery. While gastric bypass and sleeve gastrectomy are the most common, we will work with you to determine which procedure will most likely give you the best results. These operations can be done laparoscopically or robotically, depending on your body shape and scar tissue.
Gastric bypass
The Roux-en-Y Gastric Bypass (RYGB) is considered the gold standard for weight-loss surgery. During surgery, the stomach is divided into a small, egg-sized pouch, which limits the amount of food you can eat after surgery.
The bowel is re-routed, and two new connections are made: between the stomach and bowel and between two pieces of the bowel. This creates two new channels. One of the channels allows food to travel downstream from your new stomach pouch without being absorbed. The other channel allows digestive juices and enzymes to travel downstream from the other portion of your stomach, pancreas and liver.
The two channels eventually meet up when digestion and absorption begin. You will not absorb all the calories you eat or the vitamins and nutrients you need.
The average weight loss for patients who received a gastric bypass one year after surgery is 26% to 37% of the total starting weight. Most patients gain back a small amount of weight between years one to five after surgery. The average weight loss five years after a gastric bypass surgery is 28.1% of the starting weight.
Anastomosis gastric bypass (OAGB)
Anastomosis gastric bypass is a new weight-loss procedure. In this operation, the stomach pouch is left slightly larger than in an RYGB procedure and only one connection is made to the intestine. This connection is made further down the bowel so you absorb fewer calories and nutrients. The weight loss result is the same as a RYGB procedure, but some studies suggest the OAGB procedure is slightly better at improving diabetes in patients.

Sleeve gastrectomy (vertical sleeve gastrectomy)
A sleeve gastrectomy is a permanent procedure in which 80% of the stomach is removed, leaving a banana-shaped stomach. No new connections are made to the intestine, as in a gastric bypass procedure.
This is a non-reversible procedure in which a portion of your stomach is removed from the body. The operation restricts what you can eat, and hormone changes occur in the body, making you less hungry.
The average weight loss for patients who received a sleeve gastrectomy one year after surgery is 27% to 35% of the total starting weight. Most patients gain back a small amount of weight between years one to five after surgery. The average weight loss five years after a sleeve gastrectomy is 27% of the starting weight.

Single anastomosis duodenal-ileostomy with sleeve (SADI-S) or duodenal switch (DS)
This weight-loss procedure begins with a laparoscopic vertical sleeve gastrectomy, which removes a portion of the stomach.
A valve at the bottom of the stomach opens and closes to let food pass to the intestine. During a single anastomosis duodenal-ileostomy with a sleeve or a duodenal switch procedure, the intestine is divided past the bowel and reconnected to the intestine lower down the digestive tract. This limits the absorption of calories and nutrients and impacts the hormones responsible for fullness and hunger.
The average weight loss for patients who received a SADI-S or DS one year after surgery is 32% to 37% of the total starting weight. Unlike the other operations most patients continue to lose weight over the next few years. The average weight loss five years after a SADI-S or DS is 37% of the starting weight.
Revisional surgery
If you have not lost as much weight as you needed or have yet to see the health benefits you wanted following a bariatric surgery, our experts can help. Medical and surgical options are also available if you initially lost weight after surgery but have regained some.
If you have had bariatric surgery in the past, most insurance companies will pay for additional operations to manage any resulting complications.
