Why is it called Roux-en-Y gastric bypass?

Why is it called Roux-en-Y gastric bypass?

The name is derived from the surgeon who first described it (César Roux) and the stick-figure representation. Diagrammatically, the Roux-en-Y anastomosis looks a little like the letter Y.

What type of surgery is Roux-en-Y?

Roux-en-Y gastric bypass (RYGB) is a type of weight-loss surgery. Weight-loss surgery is also called bariatric surgery. It’s often done as a 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.

What is the Roux limb in gastric bypass?

This limb contains digestive juices from the stomach, bile and pancreas. The Roux limb, the middle portion of the small intestine also known as the jejunum, is connected to the pouch. Food flows directly from the pouch into the Roux limb, bypassing most of the stomach.

How does Roux en Y gastric bypass work?

Roux-en-Y gastric bypass involves creating a small gastric pouch, about the size of an egg, by stapling off the upper section of the stomach and then attaching it to a section of the intestines called the Roux limb. Simply put, this procedure both reshapes the stomach and reroutes the intestines by bypassing a large portion of the small intestine.

Is the stomach stapling and Roux en Y the same surgery?

Stomach stapling and Roux-en-Y are typically done during the same surgery and together are called a “Roux-en-Y gastric bypass.”. Usually, surgeons do both laparoscopically (using tools inserted through small cuts in the belly).

What’s the difference between biliopancreatic diversion and Roux en Y?

Because of its higher complication rate and lower rates of weight loss, it’s rarely done. Biliopancreatic diversion is similar to the Roux-en-Y gastric bypass, except the surgeon reconnects the stomach pouch to a portion of the small intestine that’s much farther down (the ileum).
