How is Gastric By-Pass Surgery Performed?

Stomach reduction surgery is a surgical method that is applied to the patients with obesity problems who could not receive sufficient results despite diet, exercise and medication. Stomach reduction surgery is based on the surgical removal of approximately 80% of the stomach, as it name suggests. After the operation, a significant change is achieved on the hormones that provide hunger-fullness and blood sugar control in the gastrointestinal tract. Since the person will receive less foods and calories as the stomach became smaller, the person will start losing weight naturally and will get rid of obesity. However, it should be noted that stomach reduction operation has some rules that should be considered after the operation.

The stomach reduction surgery is an effective procedure for the complete correction or recovery of metabolic disorders such as both diabetes and weight loss of the patient, as much as gastric bypass, which is an older surgical option. Metabolic disorders that heal after stomach reduction operation occur independently of the weight loss process. It is possible after stomach reduction surgery to turn high blood sugar levels due to diabetes to normal levels without losing weight or to partially stop using drugs and insulin for diabetes. Stomach reduction surgery has many advantages compared to gastric bypass surgery.

These may be listed as follows:

» This allows 50-60% of excess weight to be lost easily in a short time
» There is no need to adapt a foreign material to the body by surgical methods.
» After stomach reduction surgery, the metabolic disorders heal more quickly.
» The stay in the hospital is shorter.
» Requires no change in the route of passage of food in the gastrointestinal tract.

Who can receive stomach reduction (Sleeve Gastrectomy – Gastric Bypass)? What is the age range?

Prior to gastric reduction surgery, it is of utmost importance to consult with endocrinology and metabolic diseases specialists. If the metabolic values and hormonal balance are not appropriate, the surgery should not be the first option. First of all, the factors that cause obesity should be tried to be treated with diet, exercise and medication. The lifestyle should be rearranged under supervision of a specialist dietician. Surgery can be considered in cases where diet and medication are not successful. The stomach reduction (sleeve gastrectomy) may be applied to the individuals;

who applied a diet program under supervision of an expert but could not lose weight,

Whose body mass index (BMI) is beyond 40,

Whose body mass index is greater than 35 and who have a concomitant disease, and whose health is under risk.

What is BMI (Body Mass Index)?

It is division of body weight in kg by height in m2

An example for ideal BMI calculation:
75 kg/1.70 height*1.70
2,89=25,95 ( Overweight )

Accordingly, BMI was defined under 6 classes.

» Weak 18,5
» Normal 18,5-24,9
» Overweight 25-29,9 (slightly increased diabetes and cardiac disease risk)
» Obese 1 30-34,9 (Diabetes and other disease risks gradually increase)
» Obese 2 35-39,9
» Obese 3 >40 (risk of fatal diseases)

The age range of the stomach reduction surgery is 18-65 years. People under the age of 18 require parental consent and an examination for associated diseases. For people over 65 years of age, the person's general health condition and weight are evaluated together and the decision for surgery is so taken. As the stomach reduction surgery will treat the diseases related to weight while allowing the individual to get rid of his/her weights, the stomach reduction surgery is recommended to be performed in fully equipped hospitals under the supervision of a specialist doctor.

Risks for Stomach Reduction (Sleeve Gastrectomy – Gastric Bypass) Surgery

The rule that is important in obesity surgery is the correct selection of the patient for stomach reduction surgery and a body mass index greater than 35, as well as the non-presence of an associated disease. As with all operations, also in the stomach reduction operations, the choice of a hospital and specialist physician with all the necessary knowledge, experience, equipment and expertise is very important to minimize the risks associated with the reduction of the stomach against risks of complications that may occur during stomach reduction surgeries. The most serious complication following stomach reduction surgery is the leakage from the rest of the stomach into the abdominal cavity. Although gastric stenosis is rarely seen in the long term after surgery, it can be easily treated with endoscopic enlargement. It is possible to minimize your risks in a stomach reduction surgery you will undergo in a fully equipped hospital under the supervision of a specialist.
