Bariatric Surgical Procedures
The stomach is completely
divided into a small proximal
gastric pouch leaving a large
"bypassed" gastric remnant in
situ. The proximal gastric pouch is
attached to a "roux" limb of small
bowel, bypassing the large gastric
remnant, all of the duodenum,
and a portion of the proximal
small intestine.
Roux-en-Y Gastric Bypass (RNY)
The stomach is reduced to about
25 percent of its original size by
the surgical removal of a large
portion of the stomach along
the greater curvature, resulting
in a narrower sleeve or tube-like
structure. Can be used as the
first step of staged approach of
duodenal switch.
Vertical Sleeve Gastrectomy
(VSG)
An adjustable band is placed
around the upper stomach
creating a small pouch. The band
diameter is adjustable through
the percutaneous introduction
of saline via a subcutaneous port
which is accessed in the upper
abdomen.
Laparoscopic Adjustable Gastric
Banding (LAGB)
A partial gastrectomy (much like
a sleeve) is performed, removing
70–80% greater curvature of the
stomach sparing the pylorus and
a small portion of the duodenum
and the creation of a Roux-en-Y
duodenoenterostomy bypassing a
large portion of the intestine.
Biliopancreatic Diversion with
Duodenal Switch (BPD/DS)
