One of the most common surgical interventions today is sleeve gastrectomy, commonly known as “stomach reduction surgery“.

In sleeve gastrectomy, the stomach is turned into a thin long tube, almost like a banana. Laparoscopically, that is, with the closed surgery method, 80 percent of the stomach is cut out. Thus, the food intake of the stomach is restricted. In addition, gastric sleeve surgery has the effect of reducing food absorption, albeit at a very low level.

The appetite of those who undergo sleeve gastrectomy decreases. In addition, insulin resistance is broken even before weight loss.

Operation Process

What is the Duration of Stomach Reduction Surgery?

Sleeve gastrectomy surgery is performed in an average of 1.5 hours. Since the outlet and inlet sections of the stomach are preserved and the continuity in the digestive system is maintained, the risks after sleeve gastrectomy are low and some unwanted side effects are reported to be very few.

Which Stomach Reduction Surgery is Most Common?

Today, the most common stomach reduction surgery with proven effectiveness and low risk rates is “sleeve gastrectomy”. With a 15-year history, the medical name of sleeve gastrectomy is “sleeve gastrectomy”.

The other type of stomach reduction surgery applied today is ‘gastric bypass’ surgery. However, gastric bypass is preferred only in special cases; in cases where Type 2 diabetes is at the forefront and insulin use is old, and especially in people with very high BMI, gastric bypass method can be the first choice of surgery.

In addition, gastric bypass method can be applied as the second surgical method in patients who have undergone sleeve gastrectomy and regain weight.

Is Gastric Sleeve Gastrectomy Surgery Applicable to Everyone with Weight Problems?

Those who undergo gastric sleeve surgery must meet the following conditions:

Those with a body mass index above 40 kg/m² (morbid obese, i.e. severely obese).
Those with a BMI between 35-40 and have problems such as type 2 diabetes, hypertension, sleep apnea due to obesity are also considered morbidly obese and may need stomach reduction surgery.
In addition, patients with “new” type 2 diabetes and metabolic disorders due to obesity and with a BMI between 30 and 35 can also undergo surgery with the decision of the obesity doctor.

Obesity surgeries are not performed for aesthetic purposes, that is, to make the person look thinner.

Until How Old Is Gastric Sleeve Gastrectomy Surgery Performed?

Gastric sleeve gastrectomy, or stomach reduction surgery, is performed on people between the ages of 18-65. In order for a person to be a suitable candidate for gastric surgery, the Body Mass Index (BMI) values determined by the World Health Organization must be 35 and above.

For people under 18 years of age, the degree of obesity and the presence of the above-mentioned diseases are important and parental consent is required as well as the physician’s decision.

For people over 65 years of age, the health status and the necessity of the surgery (the person’s weight-related problems and the problems experienced) are evaluated.

What are Revision Surgeries After Obesity Surgery? Who is it recommended for?

Revision surgeries are surgeries performed after obesity surgery due to different complications such as weight regain, stenosis or leakage. The most important reason for revision surgeries is usually weight regain.

The main reasons for weight regain are lack of follow-up, inadequate information of the patients or failure to comply with the process even if they are conscious. For these reasons, 20-30% of patients may experience weight regain.

It is very important to choose revision surgeries well. These operations are technically more difficult and must be performed by experienced surgeons. Today, revision surgeries have also increased with the increase in the number of obesity surgeries.

There are types of surgery recommended for patients with recurrence of comorbidities such as diabetes, high blood pressure or weight regain. The most appropriate type of surgery should be decided by talking to the patient and making an evaluation.
