Gastric banding or bariatric
surgery is a surgical technique particularly designed to aid in weight
reduction for obese or morbidly obese people who normally have a body mass
index (BMI) of between 35 to 40 or occasionally a bit higher.
The technique of adjustable gastric banding surgery
The Gastric banding appliance itself is an inflated prosthetic medical
device that is put around the entrance and upper region of the patient's stomach.
A tube is linked to these banding devices via a small keyhole
laparoscopic surgical technique.
Once the gastric banding device is in position around the top of the
stomach the gastric banding device is then filled, or inflated with fluid which
then produces a tiny space at the upper end of the stomach.
The gastric banding device is generally inflated and adjusted using a
tiny access port which is normally positioned just under the surface of the
skin in the abdominal area of the patient.
A solution of saline or other non-hazardous solution is delivered into
the banded region via this port to fill the pouch.
A specialist surgical needle is utilized to avoid any injury to the
portal membrane and any corrections must thereafter be made by a competent gastric
banding Surgeon or one of His helpers who have been particularly educated in
this process.
There are various port designs in general usage today, which may be put
in varied places, depending on the surgeon's own personal choice and skills in
administering these sorts of surgeries.
The port is often stitched into place to preserve the stability of the
portal access point and also to avoid any inadvertent damage by the patient in
their regular daily life.
This pouch generally 'fills' with food fast when the patient eats and so
inhibits further transit of food from the top to the bottom portion of the patient's
stomach.
Once the gastric Banding is put to the patient's stomach, that area of
the stomach sends a subconscious message to the brain receptors that the
stomach is full.
This feeling is perceived by the brain as a sign that the stomach is now
full. This in turn allows the patient to eat smaller quantities of food and
water, with the subsequent impact of delivering the needed weight reduction
over time.
When fluid is put into the band, the band itself expanded more, and as
it expands it applies extra pressure on the exterior of the banded stomach
area.
This subsequently lowers the size
of the channel between the two sections of the stomach so reducing the transit
of food into the lower part of the stomach.
Over some time this
limitation is typically raised until the patient thinks that they have reached
a position where optimal weight loss may be attained for them, with the
smallest quantity of liquids necessary.
This is an individual preference, and multiple visits and consultations
are often necessary to fine-tune the tightness of the band and the amount of
fluid content required for each unique patient's overall comfort and weight loss
objectives
Advantages of adjustable gastric banding surgery
The Main advantages given by Gastric Banding Surgery are that it does not
require any significant surgery cuts, nor is it essential to remove any portion
of the digestive system of the patients.
Furthermore, Subsequent Removal of the Band is conceivable, although this
does need an additional keyhole surgical procedure to be conducted to remove
the device.
Once the Gastric Banding has been
removed from the patient, the stomach normally recovers to its original
pre-banded state over time without any known issues to date.
Complications of adjustable gastric banding surgery
It is rare for gastric banding patients to develop any dietary shortages
following gastric band surgery.
"Gastric dumping
syndrome" difficulties also do not generally develop with gastric banding
surgery, as no sections of the intestines or indeed of the stomach need to be
excised or re-routed.
However, weight recovery is possible as with any weight reduction
surgery including gastric banding.
Some of the more drastic treatments might initially result in fast
weight reduction although this is typically controlled and maintained
successfully in Gastric Banding scenarios.
World Health Organization recommends that a monthly weight loss of ½ to 1 kilogram
per week should be an average target weight loss for patients having gastric
banding surgery generally.
Also, the patient shouldn't document any problems to lose the target
weight, however, this can be very variable, and by the
individual patient, their personal life circumstances, their personal attitude, and mobility.
An often documented event for gastric banding patients is a regurgitation
of non-acidic food from the upper pouched region. This is usually known as
Productive Burping.
If the gastric banding Patient suffers this consistently, then they may
try eating less, eating considerably slower, and digesting their food much more
completely.
If this does not finally fix the
problem then additional medical advice must be acquired from your Practitioner
or gastric banding surgeon.
Occasionally, the tiny route at the Banded area of the stomach might get
clogged by a greater quantity of unchewed or inappropriate food.
If this occurs frequently then further modifications to your
diet should be addressed, and once again you are highly urged to visit your
gastric banding Reactionary or dietician.
In certain circumstances Ulceration or Gastritis Erosion can develop as
the band can wear and worsen a tiny region on the outside of the stomach wall
which can eventually, in extremely rare and extreme cases, lead to a migration
of the band itself into the inside of the stomach.
This however is a very extremely unusual occurrence and generally, there
are several warning indications well in advance of this ever happening
.
Slippage of the gastric Band is also an infrequent event. This occurs because the lower region of the stomach may prolapse over the band devices and produce
a blockage.
Once again though this extremely unusual event and warning indications
are generally spotted long beforehand.
The psychological implications of any weight loss surgery may also be
evaluated.
Many Patients, who have been
Obese for lengthy periods previous to the gastric banding surgical
operation, have been regularly overeating for a significant portion of their
lives.
So, any abrupt modifications to
their diet and lifestyle might have some bad consequences for the Patient.
