Roux-en-Y Gastric Bypass Using Open Surgery Method
At present, the American Society for Bariatric Surgery (ASBS) and the National Institutes of Health (NIH) consider roux-en-y gastric bypass to be one of the safest and most effective bariatric treatments for the treatment of morbid obesity. Not surprisingly it is one of the most frequently performed weight loss procedures in North America. Some obese patients may be eligible for laparoscopic roux-en-y bypass, which although a relatively new bariatric procedure is considered to be even better.
The Advantages of Open Roux-en-Y Surgery Over Laparoscopic Method
Traditional "open" bypass surgery is a more established procedure with fewer "unknowns" in terms of side effects, complications and health risks. Open bypass surgery is also quicker, which makes it theoretically safer. Longer operations result in a fall in body temperature that may interfere with the immune system, as well as a more extended general anesthesia, which may cause additional health risks.
Roux-en-Y Bypass Open Surgery Operation
Open roux-en-y surgery is conducted under general anesthesia. The operation typically lasts about 1-2 hours. Open surgery permits direct access and viewing of the operation sites in the stomach and abdominal area through the 6-10 inch midline incision in the abdomen. During the roux-en-Y bypass procedure the stomach is transected using staples. A small proximal gastric pouch (capacity 1 ounce) is created out of the upper-stomach, which is permanently separated from the lower stomach. A section of the small intestine is then connected to the pouch, diverting food flow. Finally, the bottom of the stomach is connected to the base of the new roux digestive tract or 'limb'. This permits digestive juices from the stomach and pancreas to mingle with the food and enhance nutrient absorption.
How Roux-en-Y Surgery Works
This bypass procedure is both "restrictive", as the stomach pouch restricts food intake, and "malabsorptive", as the changes to the anatomy of the digestive tract reduces the absorption of calories and nutrients.
