A Roux-en-Y Gastric Bypass operation, otherwise known as RYGB, is named after the French surgeon who devised the procedure. The technique has become one the most common methods of obesity treatment in the UK and throughout the world.
The Roux-en-Y Gastric Bypass operation involves the creation of a small pouch at the upper part of the stomach either using surgical staples or a gastric band. The pouch is separated from the rest of the stomach, and connected directly to the middle part of the small intestine.
The Roux-en-Y procedure has the combined effect of allowing less food to be consumed but also fewer calories to absorbed. As food will no longer pass all along the small intestine, there is less time for your body to absorb the calories and nutrients it contains. In effect, food passes through your system before your body can do anything with it.
A Roux-en-Y Gastric Bypass is a more favourable procedure than previous bypass techniques such as a biliopancreatic diversion stomach bypass or a duodenal switch stomach bypass. Success rates are higher, and the risk of serious complications are considerably lower. The rate of mortality is now less than on percent.
Each Roux-en-Y Gastric Bypass operation is different. One patient may have a far better chance of successful treatment than the next. Much depends on the patient's diet and lifestyle in the weeks and months following surgery. However, on average, Roux-en-Y patients are said to lose between 50 to 75% of their initial excess weight. Some patients lose considerably more but, it has to be said, some lose far less.
However, as with all forms of surgery, a Roux-en-Y Gastric Bypass operation does have many risks and possible side effects. Possible issues include leakage, nutritional deficiency, dumping syndrome, bowel problems, and temporary hair loss. The surgery itelf can causse infection, hemorrhage, hernia, and blood clots. As previously mentioned, the Roux-en-Y procedure has helped reduced the likelihood of serious complications, but patients should still be aware that things can, and sometimes do, go wrong.
