Gastric Bypass Procedures and Pictures

Gastric Bypass Procedures and Pictures

The following sections include descriptions of various bariatric
surgery procedures and links to pictures of the procedures
described.

Roux-en-Y Gastric Bypass Procedure

The Roux-en-Y gastric bypass
procedure involves creating a stomach pouch from the upper
portion of the stomach and attaching it directly to the small
intestine, bypassing a large part of the stomach and duodenum.
The small upper pouch restricts the amount of food that can be
eaten. Directly connecting to the mid-portion of the small
intestine prevents part of the calories that are eaten from
being absorbed. Together this provides a 60-80 percent loss of
excessive weight over a period of two years.

Lap-Band Gastric Bypass Procedure

The lap-band procedure consists of an adjustable silicone band
being placed around the stomach to create a small upper pouch
that restricts the amount of food that can be eaten. The band
contains a saline reservoir, which is placed just beneath the
skin and allows it to be adjusted. This procedure is the least
invasive and therefore the least dangerous. Patients still lose
40-50 percent of excess weight over a period of two years. Since
its approval, the lap band has been steadily gaining in
popularity in the United States.

Vertical Banding Procedure

Vertical Banded Gastroplasty is a non-adjustable form of banding
that uses staples to decrease the size of the stomach and
restrict the amount of food that can be eaten. Instead of
creating a small pouch at the top of the stomach, this procedure
divides the stomach length-wise and makes it smaller. This
procedure does not interfere with normal digestive processes and
has less potential complications than gastric bypass
surgery. Since the approval of the lap-band procedure, fewer
surgeons are electing to perform vertical banding on their
patients and its use is steadily declining.

Duodenal Switch Procedure

Duodenal switch produces weight loss results far surpassing
those of other severe obesity therapies. First, the stomach is
made smaller to about one-third of its original size. Then, the
intestine is divided into three pathways: two separate and a
single common pathway. Food travels through the shorter pathway,
directly to the large intestine, and bile from the liver is
diverted to the common path of the altered digestive tract. This
is one of the most invasive of all the procedures because it
makes major, permanent anatomical changes to the patient’s
digestive system. While this procedure is extremely effective,
it carries a higher risk of complications than the others. As a
result, it is rarely performed anymore.

Biliopancreatic diversion

Biliopancreatic diversion combines the removal of two-thirds
of the stomach with a long intestinal bypass, which
significantly reduces the absorption of fat. The patient can eat
more than with any other operation and the eventual weight loss
is greater. However, since most of the food is routed directly
to the colon and never digested or absorbed by the body, the
patient faces the risk of many severe and potentially fatal
nutritional deficiencies. Consequently, even though it is an
extremely effective procedure, biliopancreatic division is
rarely performed today.
