4. Laparoscopic Bariatric Procedures
Vertically Banded Gastric Bypass Surgery
Vertically banded gastric bypass consists of using a small remnant of
stomach - restricting how much the patient can eat - and a re-routing
of the usual passage of food through the intestine, altering the way the
body handles the calories and nutrients that are taken in. Gastric bypass
employs a large degree of restriction with a lesser degree of malabsoprtion.
When people go on a low calorie diet, their body undergoes a compensatory
drop in metabolic rate - a "starvation mode" - making it more
difficult to lose weight after a short period of time. Gastric bypass
largely overrides this effect to augment weight loss long term, and to
keep it off as long as patients continue to eat small amounts of food.
Many variations of gastric bypass exist, but, keeping an eye to long term
results, we prefer the vertically banded gastric bypass as it functions
to prevent some of the more common causes of surgical failure. By addressing
the issues of pouch stretching, outlet stretching, pouch to stomach re-growth
and gastro-gastric fistula, the vertically banded procedure is engineered
to result in improved long term results when compared to the conventional
gastric bypass.
Duodenal Switch
This procedure modestly restricts food intake while radically limiting
the absorption of calories, especially the obesity causing calories from
fat, complex carbohydrates, and starches. Approximately 3/4 of the stomach
is removed, but the natural outlet of the stomach, the pylorus, is left
in, allowing the stomach pouch to function more naturally. As the stomach
pouch stretches out in the first year after surgery, patients are moderately
limited in the amount of food they can eat, reduced to about 2/3 of what
they could eat before surgery. However, patients are not limited in the
types of food they are able to eat, tolerating meats and whole vegetables
without difficulty.
Revision Surgery
Sometimes it is necessary to revise bariatric operations for a variety
of reasons, but the most common reason is weight re-gain or inadequate
weight loss. Some procedures are more likely to fail than others, and
some patients are more likely to fail than others. Many times the cause
of failure can be diagnosed and often times can be surgically corrected.
Revision surgery is generally more complex and is associated with a significantly
increased incidence of pouch leaks. For this reason patients undergoing
revision surgery generally require longer hospital stays and a longer
time after surgery until they can take liquids by mouth, during which
time they are nourished by IV nutrition. Drains are usually placed in
the abdomen to clear infection should a pouch leak occur.
Dr. Husted is an expert in the field of revision surgery. Revision
surgery is extremely challenging and requires a surgeon who has advanced
experience with this procedure. A highly individualized plan of care is
developed for the patient by Dr. Husted. Many bariatric surgeons throughout
the country refer patients who require revision surgery to Dr. Husted.
Laparoscopic Procedures
Laparoscopic bariatric procedures rely on videoscopic technology. This
technology allows us to perform weight loss surgery with a minimally invasive
technique. The benefits of the laparoscopic approach allows, in most cases,
a reduced hospital stay, less pain, and earlier return to normal activities.
In addition, the wound complication and hernia risks are significantly
reduced.
