Roux-en-Y vs. Adjustable Gastric Band vs. Sleeve Gastrectomy

Roux-en-Y Gastric Bypass

Adjustable Gastric Bands

Sleeve Gastrectomy

How is the surgery performed?

 Creates small pouch in stomach using surgical staples and bypasses part of the small intestine Creates small pouch in upper portion of stomach using an adjustable inflatable band Creates a small stomach by stapling off and removing about 85% of the original stomach

How long does the surgery take?

 Usually about two hours Usually about one hour Usually about one hour

How does the surgery change the path of food?

 Pouch is connected directly to small intestine; patient no longer uses the remainder of the stomach for food Food first held in small pouch then moves slowly to larger, lower stomach Does not change path. Food just enters a smaller stomach but it proceeds through the digestive system as food did prior to surgery

How quickly do patients get back to work?

 Usually two weeks for a desk job and up to four weeks for a manual labor position Some patients go back in as few as four days, some take up to two weeks Usually about a week or two

How do patients lose weight?

 The newly formed small pouch limits the food that can be consumed and limits absorption of some calories Food passes to the lower stomach slowly, allowing patient to feel full longer and consume less food The food is going into a smaller stomach so the patient becomes full quicker and eats less food

 

How quickly do patients lose weight?

 Average of 10 pounds per month or more; usually, reach goal within 18 months of surgery Average of four to eight pounds per month; may take up to three years to reach goal Weight loss is usually a little bit more rapid than the band patient, but not as rapid as the gastric bypass patient

Special considerations
