BARIATRIC SURGERY:
There are two basic methods that the surgery of weight loss (Bariatric) applies to obtain changes. 1. Restrictive procedures that diminish the food ingestion.
2. Procedures of deficient absorption, that alter the digestion and cause that the foods have an incomplete digestion and absorption to be eliminated when evacuating them.
BARIATRIC SURGERY OPTIONS: * Gastric band Adjustable Laparoscopic:
* Gastric Sleeves or Gastrectomy
* Laparoscopic or Invasive Minimamente.
Gastric band Adjustable Laparoscopic:
The Gastric Band Adjustable is a procedure in which a band is placed superior to the stomach. This band divides the stomach in two parts, a small and greater other. The majority of the patients feel satisfaction quickly, because the food is regulated. The digestion of the food happens by means of the normal digestive process.
PROCEDURE OF GASTRIC RESTRICTION: ADJUSTABLE GASTRIC BAND LAPAROSCÓPIC
STEP 1: the stomach is inflated with a small ball to determine the size of stock-market superior. STEP 2: It inserts an adjustable band around the part superior of the stomach, to create a smaller gastric stock market and to restrict the food ingestion.
STEP 3: The placed band adjusts with the purpose of narrowing the gastric exit of stock-market superior towards stock-market inferior of the stomach, which allows the food slowly to migrate and continues the normal digestive process.
ADVANTAGES
The amount of food is restricted by what can be consumed in a single meal; - the consumed food passes through the digestive tract in a habitual way, which totally allows the individual to absorb the food consumed normaly; - in several studies of more than 3000 patients, the loss of weight varied between the 28 and 87%, with a minimum pursuit of two years later to the surgery; - the band can be fit to increase or to reduce the restriction; - the surgery can be reverted;
RISK
The gastric perforation or wears away of the gastric wall can demand an additional operation.
The casting or torsion of the access entrance can demand an additional operation.
Nausea and Vomit.
Obstruction of the exit.
Displacement or sliding of the band .
How Does The Sleeve Gastrectomy Work?
The vertical sleeve gastrectomy is a restrictive form of weight loss surgery in which approximately 85% of the stomach is removed leaving a cylindrical or sleeve shaped stomach with a capacity ranging from about 60 to 150 cc, depending upon the surgeon performing the procedure. Unlike many other forms of bariatric surgery, the outlet valve and the nerves to the stomach remain intact and, while the stomach is drastically reduced in size, its function is preserved. Again, unlike other forms of surgery such as the Roux en Y gastric bypass, the sleeve gastrectomy is not reversible.
Because the new stomach continues to function normally there are far fewer restrictions on the foods which patients can consume after surgery, albeit that the quantity of food eaten will be considerably reduced. This is seen by many patients as being one of the great advantages of the sleeve gastrectomy, as is the fact that the removal of the majority of the stomach also results in the virtual elimination of hormones produced within the stomach which stimulate hunger.
Perhaps the greatest advantage of the gastric sleeve lies in the fact that it does not involve any bypass of the intestinal tract and patients do not therefore suffer the complications of intestinal bypass such as intestinal obstruction, anemia, osteoporosis, vitamin deficiency and protein deficiency. It also makes it a suitable form of surgery for patients who are already suffering from anemia, Crohn's disease and a variety of other conditions that would place them at high risk for surgery involving intestinal bypass.
Finally, it is one of the few forms of surgery which can be performed laparoscopically in patients who are extremely overweight and these accounts for the rising popularity of the laparoscopic sleeve gastrectomy.
Perhaps the main disadvantage of this form of surgery is that it does not always produce the reduction in weight which people would wish for and, in the longer term, can result in weight regain. This is indeed true of any form of purely restrictive surgery, but is perhaps especially true in the case of the sleeve gastrectomy.
Because the procedure requires stapling of the stomach patients do run the risk of leakage and of other complications directly related to stapling. In addition .
The risk of encountering any of these complications is however extremely small and varies from about 0.5 and 1%. Having said this, the risk of death from this form of surgery at about 0 .25% is extremely small.
As a general rule the vertical sleeve gastrectomy is best suited to individuals who are either extremely overweight or whose medical condition would rule out other forms of surgery. In the case of the former vertical sleeve gastrectomy would normally form the first of a two-part surgical plan, with further bariatric surgery being performed once the patient's weight has fallen sufficiently to allow for other forms of surgery to come in to play.
Some facts about the sleeve gastrectomy:
Alternative names: vertical sleeve gastrectomy, sleeve gastrectomy, greater curvature gastrectomy, parietal gastrectomy, gastric reduction and vertical gastroplasty.
Surgery for high BMI patients. For patients with a particularly high body mass index (typically 50+) many forms of weight loss surgery are either difficult to perform or present increased risk. As a result, a vertical sleeve gastrectomy (or increasingly a laparoscopic sleeve gastrectomy) is sometimes performed as the first of a two-part weight loss solution to provide an initial drop in weight which then makes other bariatric follow up possible at a reduced level of risk.
Surgery for low BMI patients. For obese patients with a relatively low body mass index the vertical sleeve gastrectomy can also prove a good choice, especially where existing conditions (such as anemia or Crohn's disease) prevent them from having other forms of bariatric surgery. In addition, patients may choose this form of surgery if they are concerned about the long-term affects of bypass surgery or object to having a 'foreign' body implanted into their body, as is the case with lap band surgery.
Advantages of the sleeve gastrectomy:
•
Although the stomach is reduced in size and the amount of food which can be eaten is restricted, the stomach otherwise functions normally.
•
The major part of the stomach which produces hormones responsible for stimulating hunger is removed from the digestive system.
•
The problem of dumping is avoided as the pylorus is retained.
•
Minimizes the possibility of the patient developing ulcers.
•
Avoids the problems associated with bypass forms of weight loss surgery including anemia, intestinal obstruction or blockage, osteoporosis and protein and vitamin deficiency.
•
Provides a solution for patients with conditions which place them at an unacceptably high risk from other forms of bariatric surgery.
•
Provides a laparoscopic solution to patients with a particularly high body mass index (BMI).
Disadvantages of the sleeve gastrectomy:
•
As this form of surgery does not provide any element of gastric bypass some patients may experience a disappointing weight loss or weight regain.
High BMI patients will often require follow-up weight loss surgery to achieve their goal. Although this may be seen as a disadvantage by some patients, in many cases, this two procedure option not only produces the results that the patient wants but may also provide a lower overall risk for the patient. This is something which need to de discussed with your physician.
•
Patients can slow weight loss if they do not stick to a strict diet following this form of surgery.
•
Complications may occur as the result of stomach stapling.
•
The procedure is not reversible as part of the stomach is permanently removed. It should be remembered though that the sleeve gastrectomy can be extended at a later date if required by performing additional bypass surgery.
The risks and complications of the sleeve gastrectomy:
As with all forms of weight loss surgery, the vertical gastrectomy does carry risk and these will clearly vary from one patient to the next and must be discussed with your physician. Complications might include:
•
Gastric leakage and fistula 1.0%
•
Deep vein thrombosis 0.5%
What it is Obesity
The obesity is the result of an sobreaccumulation of fats that surpasses normal the skeletal and physical levels of the body. According to the National Institutes of Health (of the United States) (NIH, by its abbreviations in English), an increase of 20% or over the ideal corporal weight implies more that the overweight becomes a risk for the health. At present, 70 million of Brazilian, almost the third part of the population of the country, undergo of overweight or obesity. It is considered that approximately a million of them suffer of morbid obesity. In Brazil one of the majors preoccupations of the obese patient it is his access to the surgery; nevertheless, already the institutions are several that offer services of financing of the bariatric surgery. It gives click for greater information
Morbidly Obesity
The answer to this question can instill in you the spirit that needs to take the first step. Next the tools appear, including a table of ideal corporal weight that you can use to determine if you suffers of morbid obesity and if you are a candidate for a Bariatric Surgery. There are several accepted criteria medically to define the morbid obesity. It is probable that you suffer of it if:
your weight is more than 50 kg over its ideal corporal weight
you have an Index of Corporal Mass (IMC) superior to 40
you have an IMC of more than 35 and is undergoing serious negative effects in the health related to your overweight, such as arterial hypertension or diabetes or
If is impossible to maintain a healthful corporal weight to him during a certain time, even with a diet supervised by a doctor.
How to reduce weight with a Bariatric Surgery?
The bariatric surgeons began to recognize for the first time the possibility of obtaining the reduction of the corporal weight by surgical means conducting operations that implied the extirpation of great segments of the stomach and the intestine of the patient. After the surgical procedure the doctors noticed that, in many cases, the patients could not maintain the weight that they had before the surgery. After deeper studies, the bariatric surgeons would recommend similar modifications that could be used surely to produce the reduction of weight in patients who suffered of morbid obesity. Throughout the past decade these procedures went continuously refining with the purpose of to improve the results and of diminishing the risks. The bariatric surgeons today have access to a substantial amount of clinical information, which aid to determine to them what surgeries must use and why reasons. At present, the American Society of Bariatric Surgery describes two basic surgical methods of loss of weight to obtain the necessary changes:
1. Restrictive procedures, that diminish the food ingestion.
2. Procedures of deficient absorption that alter the digestion and basically, the surgeries of loss of weight are classified in three categories:
Básically the Lost Weight Surgery is divided in three Categories:
Restrictive Procedure, which decrease of size of the stomack to limit of ingestion of the food..
Absortion Tecnique, that reduce a part of the small intestine that is in contact with the food and in this way the body absorbe less calories.
A combination of the surgeries mentioned above which have the advantage of the both procedures restriction and absortion.
Laparoscopic Surgery Post-Operative
In most of the cases the hospitalization is approximately five to eight days after an open operation , and two to five days after a laparoscopic procedure. you will be able to leave the hospital when:
1. you can take sufficient liquids and nutrients by oral route to prevent the dehydration;
2. if you dont have fever;
3. if you are in suitable control of the pain with medicines.

The preparation for the surgery.
The surgery of loss of weight is like the other specialized surgeries. The best form to prepare yourself consists of understanding which are the risks and potential benefits of the surgery of the obesity, and of strictly following the instructions of the doctor. In order to prepare yourself mentally: - It understands how it is the surgical process and what there is to hope after this one. - It speaks with people who have been put under the surgery of loss of weight.
In order to physically prepare yourself, strictly follows the instructions from your doctor. Generally this includes, without being limited :
1)To follow a diet of only liquid transparencies between 12 and 24 hours before the surgery. –
2) To abstain to at least smoke a month before the surgery of loss of weight. –
3) To make sure to follow the instructions of its surgeon on any medicine that must take, to control other conditions of health.
4) To arrive at the decided hour, taking personal implementos for a hospital stay of three
Laparoscopic Surgery Post-Operative
In most of the cases the hospitalization is approximately five to eight days after an open operation , and two to five days after a laparoscopic procedure. you will be able to leave the hospital when:
1. It can take sufficient liquids and nutrients by oral route to prevent the dehydration;
2. It does not have fever;
3. It has an suitable control of the pain with medicines.
.Diet after the bariatric surgery
Considers the following important instructions that you must take after the surgery of loss of weight.
Modifications that have taken place in your gastrointestinal tract require permanent changes in their nourishing habits that are due to observe so that the reduction of weight is successful. The instructions post quirúrgicas diets vary according to each bariatric surgeon •
