Roux-en-Y gastric bypass surgery is a malabsorptive and restrictive type of weight-loss surgery in which a portion of the small intestine is “bypassed” to allow the bloodstream and intestinal tract to absorb fewer calories. Additionally, a portion of the stomach is stapled and made smaller to allow for the consumption of smaller food portions.
During the normal digestion process, food will pass through the stomach and enter the small intestine where the nutrients and calories are absorbed from your food. After your food becomes digested, the remainder will pass into the large intestine for excretion.
In Roux-en-Y gastric bypass surgery, your surgeon will create a new, smaller stomach pouch using a part of your existing stomach. The new pouch is usually about the size of an egg, and is directly connected to the middle portion of your small intestine. This rerouting, or “bypass,” will prevent food from passing through the rest of the stomach and the upper portion of the small intestine that generally absorbs all your calories.
Roux-en-Y gastric bypass surgery assists in weight loss by restricting the size of the stomach pouch and preventing excess calories from being absorbed by the small intestine. Weight loss occurs as a result of eating smaller portion sizes and experiencing a lower caloric intake.
Gastric Bypass surgery During Roux-en-Y gastric bypass surgery, the bariatric surgeon will make a series of small incisions across the patient’s abdominal region to prepare for surgery. The surgeon will then insert small, long-shafted instruments, including a small camera, into the stomach region to conduct surgery.
Using these instruments, the surgeon will staple a portion of the stomach to create a new small stomach pouch. Then, a portion of the small intestine is rerouted and shaped like the letter "Y" and connected to the new stomach pouch. Following surgery, any food that the patient eats will pass through the smaller stomach pouch and into the small intestine, bypassing the portion of the intestine that results in weight gain and calorie absorption.
