Roux-en-Y Gastric Bypass
About the Laproscopic Procedure
The above charicature shows the principles and surgery technique used in the Roux-en-Y Gastric Bypass.Gastric bypass surgery combines the creation of a small stomach pouch to restrict food intake and construction of bypasses of the duodenum and other segments of the small intestine to cause malabsorption (decreased ability to absorb calories and nutrients from food).
Roux-en-Y gastric bypass (RGB): This operation is the most common gastric bypass surgery performed in the U.S. First, a small stomach pouch is created by stapling part of the stomach together or by vertical banding. This limits how much food you can eat. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the duodenum as well as the first portion of the jejunum. This causes reduced calorie and nutrient absorption. This procedure can now be done with a laparoscope (a thin telescope-like instrument for viewing inside the abdomen) in some people. This involves using small incisions and generally has a more rapid recovery time.
Advantages to Gastric Bypass Surgery
More rapid weight loss following surgery than with purely restrictive methods
Smaller stomach limits amount of food that can be eaten at any one time
Intestinal rerouting limits amount of calories absorbed by the body
Intake of sweets controlled because of Dumping Syndrome
Resolves and/or improves certain obesity-related health conditions as weight loss occurs
Disadvantages to Gastric Bypass Surgery
Complex operation, surgery risks include infection, leaks, and blood clots
Vitamin and mineral deficiencies, can lead to metabolic bone disease and anemia
May experience ulcers, bowel obstruction, or reflux
Dumping Syndrome
What To Expect After Surgery
Most people can return to their normal activities within 3 to 5 weeks.
Gastric bypass surgeries may cause dumping syndrome. This occurs when food moves too quickly through the stomach and intestines. It causes nausea, weakness, sweating, faintness, and possibly diarrhea soon after eating. These symptoms are made worse by eating highly refined, high-calorie foods (like sweets). In some cases you may become so weak that you have to lie down until the symptoms pass.
Why It Is Done
Although guidelines vary, surgery is generally considered when your body mass index is 40 or higher or you have a life-threatening or disabling condition related to your weight.
Your doctor may only consider doing gastric bypass surgery if you have not been able to lose weight with other treatments.
The following conditions may also be required or are at least considered:
You have been obese for at least 5 years.
You do not have an ongoing problem with alcohol.
You do not have untreated depression or another major psychiatric disorder.
You are between 18 and 65 years of age.
All surgeries have risk, and it is important for you and your health professional to discuss your treatment options to decide what is best for your situation.
For many obese or overweight Americans, shedding weight has led them to lifestyle changes, such as a healthier diet and a new exercise regimen.How Well It Works
Most people who have gastric bypass surgery quickly begin to lose weight and continue to lose weight for up to 12 months. One study noted that people lost about one-third of their excess weight (the weight above what is considered healthy) in 1 to 4 years. 1 Some of the lost weight may be regained.
The laparoscopic approach showed similar results, with 69% to 82% of excess weight lost over 12 to 54 months.
Risks
Risks common to all surgeries for weight loss include an infection in the incision, a leak from the stomach into the abdominal cavity or where the intestine is connected (resulting in an infection called peritonitis), and a blood clot in the lung (pulmonary embolism). About one-third of all people having surgery for obesity develop gallstones or a nutritional deficiency condition such as anemia or osteoporosis.
Fewer than 3 in 200 (1.5%) people die after surgery for weight loss.
After a Roux-en-Y gastric bypass:
An iron and vitamin B12 deficiency occurs more than 30% of the time. About 50% of those with an iron deficiency develop anemia.
The connection between the stomach and the intestines narrows (stomal stenosis) 5% to 15% of the time, leading to nausea and vomiting after eating.
Ulcers develop 5% to 15% of the time.
The staples may pull loose.
Hernia may develop.
The bypassed stomach may enlarge, resulting in hiccups and bloating.
What To Think About
In a gastric bypass, the part of the intestine where many minerals and vitamins are most easily absorbed is bypassed. Because of this, you may have a deficiency in iron, calcium, magnesium, or vitamins. This can lead to long-term problems, such as osteoporosis. To prevent vitamin and mineral deficiencies, you may need to work with a dietitian to plan meals, and you may need to take extra vitamin B12 as pills, shots, or nasal spray.
There is also a possibility that you may develop gallstones after gastric bypass. Sometimes the gallbladder is removed as part of the surgery. But if your gallbladder is not removed, then you may need to take medicine to prevent gallstones.
Early studies of the laparoscopic approach to surgery for obesity suggest that it reduces recovery time and postsurgery complications.
