Simplified Gastric Bypass
What is the Simplified Gastric Bypass?
The Gastric Bypass is considered by the American
Society of Bariatric Surgeons and the National
Institutes of Health the gold standard of weight
loss surgery. The gastroplasty with an intestinal
Bypass can be done by laparoscopy ore
conventionally by open surgery. This technique
involves a gastric stapling and division (forming
the gastroplasty or new gastric chamber) reducing
the gastric capacity in 90% (20-30cc)and a
intestinal bypass with 1,5 to 2m (the small bowel
have anything between 4 to 7m), at the end the
gastroplasty is communicated with the deviated
small bowel (gastrojejunostomy) by the means of
stapling and suture, allowing the food to pass
again.
The technique developed by Dr. Almino called
Simplified Lap Bypass is nothing more than
simplifying and standardize the steps of the
traditional Gastric bypass (considered by the
SAGES and ASBS the most complex procedure to be
done by laparoscopy) in the way that it can be
done with less operative time (average of
65minutes) and efficiency (more than a thousand
patients operated by this technique)

the Bypass have its remarks.
Bypass fits to / combines with...
o Sweet eaters
o Any degree of binging eaters
o Moderate risk patients
o High expectations / needs to loose weight
o Low / moderate patient commitment
o Not that close follow-up
o T.P.C. at his beginning
o Up to 80% EWL (excess weight loss)
How it Works?
This kind of operation mix restriction with
malabsorption. The restriction is predominant over
malabsorption and the gastrojejunostomy is
calibrated to 11mm. The food arrives at the new
stomach (gastroplasty) and promotes distention on
the walls of this pouch inducting satiety and
fullness with small amounts of food. Than the food
passes slowly trough the calibrated
gastrojejunostomy and goes to make the digestion
1,5 to 2m after the pouch on the bypass. If the
restriction caused by the small chamber was
exceeded the fullness sensation will get worse and
vomiting can occur. If the patient continues or
initiate drinking liquids with high concentration
of carbs it will wont be totally absorbed and can
causes bowel irritation leading to abdominal pain
and diarrhea.
How is the post-op?
Most of our patients go home within 30 to 36 ours
after the operation, during 4 weeks they go on a
liquid diet and advance in a stepwise way to a
puree/baby food type diet for one or more
additional weeks and evolving to a almost normal
diet after that. The complete return to normal
activities occurs in about one week. In this
operation there is a minimum need to supplement
vitamins and minerals if necessary. Iron must be
followed by regular I.V. tests and reposition may
be needed
What are the results in weight loss with the
Gastric bypass?
With the bypass, the mean % of excess weight loss
is about 70 to 85%. For example, one patient with
140Kg of weight, 1,70m of height and a 48 of BMI,
has an average excess weight of 65Kg. With the
Gastric band he should loose an average of 60Kg
going to 80Kg and a BMI of 27.
The Gastro Obeso Center between December of 2001
and October of 2005 operated 1395 patients with
the Simplified Lap Bypass and. The mean BMI comes
from 45 to 27,4 and the %EWL goes to 75% with a
mean drop of 40% of the initial total weight in a
two years follow-up in a T.P.C. environment
What are the risks in gastric bypass surgery?
International literature describes an average of
10% in complications and a mortality rate between
1 and 2%. Our numbers goes to a 7,5% complication
rate and 0,2% overall mortality rate with no
deaths in the last 1000 cases of this series.

Vertical Banded Gastroplasty with Bypass/ Fobi –
Capella operation
What is the so called Fobi- pouch operation or
Capella operation or Vertical Banded Gastroplasty
with bypass?
It is a weight loss surgery done by laparoscopy
ore conventionally by open surgery and also a
variation of the traditional Gastric Bypass. This
technique involves a gastric stapling and division
(forming the gastroplasty or new gastric chamber
that is larger than in bypass) reducing the
gastric capacity in 80% (50cc), followed by
placing a silastic ring around the gastroplasty
with 5,5 to 6,2cm. After that, a intestinal bypass
with 1 to 1,5m (the small bowel have anything
between 4 to 7m) is done and at the end the
gastroplasty is communicated with the deviated
small bowel (gastrojejunostomy) by the means of
stapling and suture, allowing the food to pass
again

the Bypass have its remarks.
Like Bypass, it fits to / combines with...
o Sweet eaters
o Any degree of binging eaters
o Moderate risk patients
o High expectations / needs to loose weight
o Low / moderate patient commitment
o Not that close follow-up
o T.P.C. at his beginning
o Up to 80% EWL (excess weight loss)
How it Works?
This kind of operation mix restriction with
malabsorption. The restriction is even more
predominant than the traditional gastric bypass
over malabsorption caused by the silastic ring
passed around the gastroplasty who reduce the
gastroplasty distension. As the some way of
bypass, the food arrives at the new stomach (gastroplasty)
and promotes distention on the walls of this pouch
inducting satiety and fullness with small amounts
of food. Than the food passes slowly trough the
calibrated gastrojejunostomy and goes to make the
digestion 1,5 to 2m after the pouch on the bypass.
If the restriction caused by the small chamber was
exceeded the fullness sensation will get worse and
vomiting can occur (more frequently than in
non-banded gastric bypass). If the patient
continues or initiate drinking liquids with high
concentration of carbs it will wont be totally
absorbed and can causes bowel irritation leading
to abdominal pain and diarrhea
How is the post-op?
The some way of the Bypass, most of our patients
go home within 30 to 36 ours after the operation,
during 4 weeks they go on a liquid diet and
advance in a stepwise way to a puree/baby food
type diet for one or more additional weeks and
evolving to a almost normal diet after that. The
complete return to normal activities occurs in
about one week. In this operation there is a
minimum need to supplement vitamins and minerals
if necessary. Iron must be followed by regular
I.V. tests and reposition may be needed
What are the results in weight loss with the
Vertical banded Gastroplasty?
With the vertical banded gastroplasty, our results
are the closed to the Bypass, the mean % of excess
weight loss is about 70 to 85%. For example, one
patient with 140Kg of weight, 1,70m of height and
a 48 of BMI, has an average excess weight of 65Kg.
With the Gastric band he should loose an average
of 60Kg going to 80Kg and a BMI of 27.
The Gastro Obeso Center between July of 2000 and
October of 2005 operated 1080
patients with the Vertical Banded Gastroplasty.
The mean BMI comes from 46 to 27 and the %EWL goes
to 75% with a mean drop of 40% of the initial
total weight in a three years follow-up in a T.P.C.
environment.
What are the risks in gastric Vertical banded
Gastroplasty?
International literature describes an average of
10% in complications and a mortality rate between
1 and 2%. Our numbers goes to a 6,7% complication
rate and 0,1% overall mortality rate with no
deaths in the last 500 cases of this series.

Adjustable Gastric Band
What is the adjustable gastric Band surgery ?
It is a weight loss surgery, done by laparoscopy
in witch a inflatable silicone band is placed
around the stomach without cutting or stapling it
on its superior third in reducing the capacity of
the stomach to an average of 15 to 20ml, which
restricts the amount of food that can be consumed.
The band is connected by the means of a catheter
to a porth placed in patients subcutaneous space
with allows band inflation to modulate the food
intake
Who should do the gastric band?

the band have its remarks.
Band fits to / combines with...
o Less pain / Less complication
o Early discharge and return to regular activities
o Teens / Aged
o “Volume” eaters
o High risk patients
o Moderate expectations to loose weight
o High patient commitment
o Surgeons with “Gastric Band Culture”
o Close follow-up
o T.P.C. fully operational
o Almost Zero Mortality
How it works?
This is a restrictive procedure in witch the food
arrives at the reduced stomach or pouch distending
the walls of this chamber promoting satiety and
fullness with small amounts of food. The food
passes slowly trough the “big’ stomachs were the
digestion takes place. If the restriction caused
by the small chamber was exceeded the fullness
sensation will get worse and vomiting can occur.
In this kind of operation only the excess of solid
food is not tolerated by the restriction. Liquids
can pass almost freely and cause of this, if the
patient continues or initiate drinking liquids
with high concentration of carbs this operation
can be cheated and the patient stops loosing
weight.
How is the post-op?
Most of our patient goes home at the some day or
day after the surgery. During the first 3 weeks
the diet is based on liquids and after that we
increase in a stepwise way to a puree/baby food
type diet for one or more additional weeks
evolving to a almost normal diet. The complete
return to normal activities occurs in about one
week
What are the results in weight loss with the
gastric band?
With the band, the mean % of excess weight loss is
about 50 to 60%. For example, one patient with
140Kg of weight, 1,70m of height and a 48 of BMI,
has an average excess weight of 65Kg. With the
Gastric band he should loose an average of 45Kg
going to 95Kg and a BMI of 32.
The Gastro Obeso Center between December of 199
and December of 2005 operated 1252 patients with
the adjustable gastric band. The mean BMI comes
from 48 to 30,1 and the %EWL goes to 65% with a
mean drop of 30% of the initial total weight in a
four years follow-up in a T.P.C. environment
What type of Gastric Band we use?
There is at list 5 brands of adjustable gastric
band in the market. The two most known is the
Lapband made by INAMED company and the Swedish
Adjustable gastric Band (SAGB) made by Ethicon
company. The Lapband is an FDA approval device and
the SAGB is running trials to be FDA approved,
otherwise it is approved to be used in Europe
(with CE mark) as the Lapband. The lapband has a
high pressure low volume band filling system and
the SAGB has a low pressure high volume filling
system witch we prefer. Other Bands come from
France (Heliogast Band made by Helioscopie company
and Midband done by MID company) and Germany (
Softband made by AMI company) are approved to be
used there. In Brazil the ministry of health have
approved all of them. Our group is experienced
with almost all types of bands and we are using
the SAGB in the last 900 cases
What are the risks in gastric band surgery?
International literature describes an average of
10% in complications (most of them minor
complications) and a mortality rate less than 1%.
Our numbers goes to a 7,9% complication rate and
zero mortality in this series
This procedure is for life? How much time does the
band can be held in place?
The intention is to be a definitive procedure for
life. The band do not have specific time limit to
be in place. Besides, if the patients for any
reason have the desire or the need, the band can
be removed by laparoscopy.

Bilio Pancreatic Diversion (B.P.D.)
What is the Bilio Pancreatic Diversion (B.P.D.)?
There are two types of BPD surgery; one is the
Scopinaro procedure and the other is the Duodenal
Switch, both works almost in the same way. It is a
weight loss surgery that can be done by
laparoscopy ore conventionally by open surgery.
In the Scopinaros procedure, an average of 50% of
the stomach is stapled and divided horizontally
with or without a partial gastrectomy (stomach
removal), followed by a very distal bypass with
the ileum (end of small bowel) leaving only 50-80
cm, making a common channel were the digestion
takes place, at its end, the remained stomach is
connected to the small bowel (Ileum) with a 2,5m
alimentary limb by the means of stapling and
suturing (gastroileostomy).
In the Duodenal Switch procedure, an average of
50% of the stomach is stapled and divided
vertically with a partial gastrectomy (stomach
removal) preserving the pylorus and part of the
duodenum followed by a very distal bypass with the
ileum (end of small bowel) leaving 80-100 cm,
making a common channel were the digestion takes
place, at its end, the remained stomach on
duodenum is connected to the small bowel (Ileum)
with a 2,5m alimentary limb by the means of
stapling and suturing (gastroileostomy).
Who should do the BPD?
Despites the indication for bariatric surgery (Am
I a candidate to Weight Loss Surgery?)
the BPD have its remarks.
It fits to / combines with...
o Protein (animal) eaters
o Severe degree of binging eaters
o Super obese patients (BMI >50)
o High expectations / needs to loose weight
o Low patient commitment
o Not that close follow-up
o T.P.C. at his beginning
o Up to 90% EWL (excess weight loss)
How it Works?
In this kind of bariatrc procedures, malabsorption
rules over restriction. The place were the food
will gone mix with intestinal enzymes and liquids
and make the digestion is located near (50-100cm)
to the end of the small bowel and is called common
alimentary channel. So, most of the ingested food
will not be digested.
Having minimum restriction allows the patient to
stay in his regular diet (protein ingestion is
stimulated) even with large amounts of food,
because most of them will not be absorbed. The
patient has to be warned that ingesting large
amounts and greasy food can and probably will
cause diarrhea and bad smell stools
How is the post-op?
The same way of the Bypass, most of our patients
go home within 30 to 36 ours after the operation,
the diet is advanced more quickly than in the
bypass and after 2 weeks of a liquid diet it
advances in a stepwise way to a puree/baby food
type diet for one or more additional week and
evolves to a almost normal diet after that. The
complete return to normal activities occurs in
about two weeks.
In these types of operations there is a need to
supplement vitamins and minerals in a lifelong
way, Iron and protein also must be followed by
I.V. test and reposition may be needed
What are the results in weight loss with the BPB
operations?
With the BPD, the expected mean % excess weight
loss is 85 to 95%. For example, one patient with
140Kg of weight, 1,70m of height and a 48 of BMI,
has an average excess weight of 65Kg. With the
Gastric band he should loose an average of 63Kg
going to 77Kg and a BMI of 25.
The Gastro Obeso Center between December of 2001
and December of 2005 operated 149
patients with the BPD procedure. The mean BMI
comes from 49 to 26,8 and the %EWL goes to 83%
with a mean drop of 44% of the initial total
weight in a two years follow-up in a T.P.C.
environment
What are the risks in BPD?
International literature describes an average of
15% in complications and a mortality rate between
1 and 3%. Our numbers goes to a 11,2% complication
rate and a 1,1% mortality rate in this series.

Intragastric Balloon
What is the intragastric Balloon?
The intragastric Balloon is a procedure in witch a
silicone balloon is placed by upper endoscopy
inside the stomach and filled with saline solution
plus a biocompatible substance called methylene
blue. It is placed in ambulatory bases and filled
until it reaches 400 to 700ml. It’s also a
temporary treatment with the balloon removed by
endoscopy at 6 months
How it works?
The 400 to 700ml of liquid in the balloon take
place in the stomach adding restriction to the
food intake, also, fullness occurs with small
amount of food, reaching by this way the weight
loss
What are its indications?
Patient with BMI between 33 to 39 Kg/M2
Patients with BMI over 40 Kg/M2 that refuses
surgery or can have it due to clinical
restrictions
Pre-operative preparation to patients over 50
Kg/M2 (super-obese) to reduce surgical risks
Patients with BMI over 27 with co-morbid
conditions such as diabetes and hypertension
What are the results of intragastric balloon ?
The Brazilian Intragastric Balloon Multicentric
Study with a reference in medical literature shows
at his end an average reduction of 1/3 (30%) of
its initial excess weight. For example a patient
with 40Kg of excess looses an amount of 12Kg
within the 6 months of treatment and so. Our
results in 291 cases were similar to the Brazilian
Multicentric study
Is there a place for medical treatment with the
balloon?
The group who make complementary diet and
exercises benefits from a more consistent weight
loss
Can the intragastric balloon be compared with the
surgical treatment?
No, the intragastric balloon has superior results
when compared with the clinical management of
obesity, but when comparing with the surgical
treatment it is inferior in terms of weight loss.
Also remembering its temporary nature
What are the complications with intragastric
balloon?
The Brazilian Intragastric Balloon Multicentric
Study shows that with this method the occurrence
of temporary nausea, vomiting, abdominal pain and
dehydration. Gastric or personal intolerance e
balloon that leads to an early balloon removal can
occur but it is rare (we had two cases). Balloon
deflation was related in cases that were not
removed after the 6 months time .
How the balloon is removed? What happens after the
removal?
The balloon is removed 6 months after its
implantation. The patient can change one balloon
to another (we do not recommend more than 3
changes) for more 6 months, can go to bariatric
surgery or can enter in a maintenance weight
program. At least 50% of the patients keep their
weight after the balloon had been removed.
