The Gastric Bypass Surgery in
medical terms
In the gastric bypass procedure, a 15-20cc stomach pouch is
constructed (usual stomach approximately 1500cc or greater). The
remainder of the stomach is separated from the new stomach pouch and
stapled closed. This part of the stomach is not removed. The new
stomach pouch is then connected to the small intestine. This is done
by dividing the intestine approximately 40cm from the stomach and
attaching the distal part to the stomach pouch. The proximal part of
the divided intestine is then connected to the side of the intestine
that was previously attached to the pouch. The roux limb is that
part of the intestine between the stomach pouch and the connection
to the proximal small intestine.
