Laparoscopic Roux-en -Y gastric bypass
How We Do the Operation
When we do the Gastric Bypass, we want to make a very small pouch out of the upper stomach, to restrict the amount of food which can be eaten. That pouch is separated from the rest of the stomach, which is bypassed, by creating a new pathway into the intestines.
Laparoscopy is done through “ports”, which are tubes that we pass instruments through, to operate on the internal organs. We place several of these in the abdominal wall, through tiny incisions. Whether we do the operation through an incision, or laparoscopically,
the basic methods, anatomy, and the results are similar,
although the instruments differ.

Disadvantages:

- Nutritional/ mineral supplements required
Residual stomach capacity: 10-15 mls
Estimated weight loss: 60-70% EWL over 2 years.
