What is a Roux-en-Y in medical terms?
Overview. Gastric bypass, also called Roux-en-Y (roo-en-wy) gastric bypass, is a type of weight-loss surgery that involves creating a small pouch from the stomach and connecting the newly created pouch directly to the small intestine.
Why do you do a Roux-en-Y?
A Roux-en-Y (say “roo-en-why”) gastric bypass is surgery to make the stomach smaller and change the connection between the stomach and the intestines. It is done to help people lose weight. The surgery limits the amount of food the stomach can hold. This helps you eat less and feel full sooner.
Is Roux-en-Y same as a sleeve?
In sleeve gastrectomy, the majority of the stomach is vertically resected and a tube-shaped remnant is left along the lesser curvature. In Roux-en-Y gastric bypass, a small gastric pouch is connected to the small intestine, bypassing the stomach, duodenum, and the proximal part of the jejunum.
How much weight do you lose with Roux-en-Y?
Gastrointestinal weight loss surgery, particularly Roux-en-Y gastric bypass (RYGB), has proven to be an effective long-term treatment for obesity. Studies have revealed that after this operation patients lose an average of 60–75% of their excess body weight and maintain >50% excess body weight loss for >15 years (7,8).
Why is it called Roux NY?
The Roux-en-Y is named after the Swiss surgeon César Roux (1857-1934), who was Chief of Surgery at the county hospital of Lausanne and following the opening of the new University of Lausanne, in 1890, was its inaugural Professor of External Pathology and Gynecology 4.
Can gastric bypass reversed?
Gastric bypass or Roux-en-Y gastric bypass operations are reversible, but the reversal procedure is risky. The attempt to reverse the bypass to normal anatomy can cause rare but serious complications. The parts of the stomach and small intestine can be put together again but their function will never be quite the same.
Can you reverse Roux-en-Y?
Background: Roux-en-Y gastric bypass (RYGB) can be reversed into normal anatomy (NA) or into sleeve gastrectomy (NASG) to address undesired side effects. Concomitant hiatal hernia repair (HHR) may be required.
What are the 3 weight-loss surgery options?
