What is RNY Gastric Bypass?
RNY gastric bypass is a type of weight loss surgery. Weight loss surgery is also called bariatric surgery. It is usually done as laparoscopic surgery with small incisions in the abdomen.
This surgery reduces the size of your upper stomach to a small pouch about the size of an egg. The surgeon then connects this sac directly to the part of the small intestine called the Roux limb. This creates a “Y” shape. Food bypasses the rest of the stomach and the upper part of your small intestine, which reduces the amount of fat and calories you get from the foods you eat. It also reduces the amount of vitamins and minerals you get from food.
Why Is Gastric Bypass Weight Loss Surgery Needed?
Gastric bypass surgery is used to treat severe obesity. It is recommended for people who have tried other weight loss methods without long-term success. If you are severely obese with a body mass index (BMI) over 40, your doctor may recommend gastric bypass surgery. Your doctor may also recommend it if your BMI is between 35-40 and you have a health condition such as sleep apnea or high blood pressure. It can also be applied for heart disease or type 2 diabetes.
Gastric bypass can help a person lose about 100 kg of excess weight. It can be good for type 2 diabetes, stop heartburn and reflux. Also, this surgery can reduce the risk of sleep apnea, high blood pressure, and certain heart conditions.
What Happens During Roux-En-Y Gastric Bypass Surgery?
The surgery usually takes a few hours. You will receive general anesthesia for your surgery. This will help you sleep and not feel pain during the surgery.
Your surgeon may use laparoscopy. It makes several small incisions in your abdomen. The surgeon will then insert a laparoscope and insert small surgical instruments into these incisions.
The doctor uses a laparoscopic stapler to make a small stomach pouch with the top of your stomach. It then separates the upper part of your small intestine into a two-pronged tube.
One end of the small intestine (Roux limb) is brought up to the stomach pouch and a small connection (anastomosis) is made between them. The other end of the small intestine is then connected to another part of the small intestine. Your surgeon may then perform a leak dye test or upper endoscopy.
