Roux-en-Y Gastric Bypass ... RNY
The roux-en-y gastric bypass is the most commonly performed bariatric surgery in the world with around 100,000 procedures being performed annually, the majority in the United States.It combines the two types of surgery being both a restrictive and partly malabsorptive operation.Stapling is used to create a smaller, upper stomach pouch which restricts the amount of food able to be consumed.A portion of the small bowel is bypassed thus delaying food from mixing with digestive juices to avoid complete absorption
All major surgery involves a certain level of risk, the following risks and considerations are specific to this procedure.
Poor absorption of iron and calcium
Chronic anaemia due to Vitamin B12 deficiency
Dumping syndrome can occur when too much sugar or large amounts of food are consumed
Stomach pouch stretching
Bypassed stomach and small bowel are unable to be easily visualised with normal x-rays and endoscopy
