Roux-En-Y Gastric Bypass Anatomy

The final result of the surgery creates the so called Roux-En-Y gastric bypass anatomy, an anatomical structure that is way different compared to the anatomy of a normal digestive system. The Roux-En-Y method is the most common form of gastric bypass surgery nowadays. A variation of the surgical procedure that was first performed in 1967, it is a procedure that is considered to be both restrictive and malabsorptive at the same time. The Roux-En-Y gastric bypass anatomy represents a major deviation from the normal configuration of the human digestive system. It involves the anastomosis of a huge portion of the stomach and the small intestine. So how is the Roux-En-Y gastric bypass anatomy created?

Steps of a Gastric Bypass Anatomy

The first step is artificially dividing the stomach. How is it going to be done? The upper portion of the stomach is divided and stapled, creating a small pouch that can only accommodate up to 2 ounces of food. This is the so-called restrictive part of the surgery, as it restricts the amount of food that the person can take in. Eventually, this pouch can expand to take about 6 ounces of food, but still it is a far cry from the capacity of a normal stomach. As expansive as it may sound, this is only one half of the Roux-En-Y gastric bypass anatomy.

The second half of the Roux-En-Y gastric bypass anatomy is a shortened small intestine. Using a combination of staples and sutures, a Roux limb is created, named after Dr. Phillibart Roux, a French surgeon. What is done here is that the jejunum, the second section of the stomach, is the one that is connected to the pouch located at the stomach. This effectively shuts out the duodenum, the most proximal part of the small intestine. This is where this surgery gets its malabsorptive function. It is a fact that the duodenum is the most absorptive among the parts of the intestines, and shutting this part out means that the ability of the body to absorb nutrients, including calories, is largely impaired.

The result of this modified Roux-En-Y gastric bypass anatomy is both a reduced eating capacity and a reduced absorptive capacity. These 2 combine to create rapid weight loss that is unattainable even by other methods of gastric bypass surgery. In fact, those that underwent a Roux-En-Y procedure are found to lose in between 50 to 70 percent of their excess body weight. That is a large decrease in every sense of the word.

There are a set of pros and cons for an extensive surgical procedure like this. For starters, the biggest benefit is weight loss. As you eliminate body mass, you become less suspect to obesity related complications such as high blood pressure, diabetes, obstructive sleep apnea, and all others involved with excess weight. There are also disadvantages. A possible case of malnutrition, as well as embolisms, could be encountered. Any surgery is a risk, and you will want it to be as sure as you can get. Now that you know the basics about the drastic changes a Roux-En-Y gastric bypass anatomy can make, it is up to you to create an informed decision together with your doctor.
