Roux-en-Y Gastric Bypass
Here a small stomach pouch is created to restrict food intake.
Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the lower stomach, the duodenum (the first segment of the small intestine), and the first portion of the jejunum (the second segment of the small intestine). This bypass reduces the absorption of nutrients and thereby reduces the calorie intake.
Gastric Bypass has been the most popular operation in USA and parts of Europe for many years particularly as it can now be done laparoscopically. However its popularity is waning as more surgeons have taken up Lap Sleeve and band.
At Mercy Bariatrics we have reserved Gastric bypass as a revision operation for failed other surgery and currently it would need to be performed as open not laparoscopic surgery.
