Roux-en-Y Gastric Bypass

vb1The Roux-en-Y Gastric Bypass combines restrictive and malabsorptive procedures and comprises 75 percent of bariatric surgical procedures.

  • During the procedure, stapling is used to create a small, upper-stomach pouch that restricts the amount of food able to be consumed.
  • A portion of small intestine is bypassed and connects the new stomach pouch with the remainder of the small intestine.
  • This bypassed limb delays food from mixing with digestive juices to avoid complete caloric absorption.
  • The malabsorption obtained after the gastric bypass is not to the extent as after true malabsorption operations (biliopancreatic bypass/duodenal switch).
  • Weight loss is achieved by drastically limiting the amount of food or liquids that a patient can ingest.
