What is Gastric Bypass with Transit Bipartition (Roux-En-Y Anastomosis)?


Roux-en-Y Gastric Bypass is an operation applied both in obesity and metabolic surgeries.  Roux-en-Y Gastric Bypass does consist of two stages. First, a small 30-milliliter gastric pouch that connects with the esophagus is created. Small intestines are separated from the point where they can easily reach the formed stomach pouch and the lower small intestine part is pulled up and connected to the new stomach pouch. The upper part of the small intestine separated in the second stage which is connected to the 150 cm of the intestine connecting to the stomach. The operation is performed with laparoscopy.

Since the gastric pouch is small, daily food and calorie intake is restricted. Since a certain part of the small intestine is bypassed in these type of bariatric and metabolic surgeries, the total length of the intestine through which food is digested and absorbed shortens. Thus, the amount of calories and fat taken into the body is reduced while creating malabsorption. The amount of some intestinal hormones secreted depending on the newly formed digestive tract changes, the feeling of hunger is lessened, the patient feels satiety and the sugar in the blood is regulated and type-2 diabetes is treated. With this type of bariatric surgery, there is a chance that the patient will approximately lose between 60 to 80% of his/her excessive weight. This type of bariatric surgery is also frequently used as a revision surgery.

Am I eligible for having a Gastric Bypass with Transit Bipartition (Roux-En-Y Anastomosis)?

I am eligible for having Gastric Bypass with Transit Bipartition (Roux-En-Y Anastomosis):

• If I have a body mass index (BMI) of 40 and above (It is also called ‘’Advanced Obesity’’)

• If my body mass index (BMI) is between 35 and 39.99 (This is classified as Obesity) and if I have serious obesity-related health issues. Such as, Hypertension, Severe Sleep Apnea, Type 2 diabetes, and such.

Note: Even in some cases, if the BMI of the patient is between 30 – 35 surgery can be performed if you have serious weight-related health problems. The decision on this will be made by surgeons and health professionals based on medical history of the patient with good standing medical reasons.

It is the most crucial part for patients who have had a gastric bypass surgery to make an ever-lasting commitment for the important changes in their diet and commiment for exercising regularly. This includes maintaining a sufficient level of protein, vitamins and minerals while continuing to use multivitamins; such as, B12, iron, and calcium. In this change, sweets and fatty foods have to be avoided for life. However, not every patient requires vitamin supplements for a long period.
