Roux-en-Y
Gastric Bypass Operation
This malabsorptive operation is one of the most popular types of gastric bypass surgeries in America.
Gastric Stapling to Create Pouch
During the Roux-en-Y operation, the surgeon transects the stomach into a small upper section (the pouch) and a larger lower section using gastric staples.
Y-Shaped Bypass Procedure
The lower (distal) part of the stomach is then bypassed, together with the first portion of the small intestine (duodenum and jejunum). The small intestine is cut at this point and connected directly to the new stomach pouch. Food now travels from the pouch directly into the lower part of the small intestine, bypassing the lower stomach and first section of the intestine.
However, although food does not flow down this bypassed segment, it is still functioning because it carries the normal digestive juices from both the stomach and pancreas. These juices are allowed to flow out of the stomach and through the duodenum and jejunum which is then re-connected to the "Roux limb" (forming the Y shape).
Reduction in Nutrient Absorption
In this way, the Roux-en-Y gastric bypass forces food to bypass the lower stomach, the duodenum, and the first portion of the jejunum, which means a reduction in the amount of calories and nutrients which the patient can absorb. See also Fobi Pouch
