This keyhole procedure is one of the original and most effective weight loss surgeries designed to help those suffering from morbid obesity. Its name is a French term meaning “in the form of a Y”.
First, the stomach is divided into a smaller top portion (pouch) which initially holds around 30mls. The larger part of the stomach is bypassed and no longer stores or digests food.
The small intestine is also divided and joined to the new stomach pouch to allow food to pass. The small bowel segment which empties the bypassed stomach is connected into the small bowel approximately 1.5m downstream, resulting in a bowel connection resembling the shape of the letter Y.
This means that digestive fluids and food meet further downstream, and the end result is a shorter “common channel” for digestion and absorption of nutrients.
