Gastric sleeve surgery is a method developed to combat obesity and the associated health risks. This procedure consists of specific phases and steps. The successful completion of each of these steps is crucial to the success of the surgery.

What is gastric sleeve surgery?


Gastric sleeve surgery is a surgical procedure in which approximately 80% of the patient’s stomach is removed. As a result of this procedure, patients feel full with less food and therefore consume less. This situation allows patients to lose weight quickly and reduce themselves from obesity.

Obesity is a situation in which fat mass is significantly higher compared to muscle mass. These ratios are determined by special examinations. However, the body mass index (BMI) is also an important measure to determine this ratio or to find out its meaning.

A person with a body mass index (BMI) of 30 or higher is considered obese. The most basic method of overcoming obesity is diet and exercise. However, due to various reasons, some people may not be sufficiently successful in losing weight through diet and exercise, and their body fat percentage increases rapidly. In such cases, gastric sleeve surgery is a helpful measure that helps to facilitate weight loss and achieve positive effects.

Gastric sleeve surgery goes through various phases. Before these steps are initiated, however, it is important to determine whether patients are suitable candidates for this procedure. For this reason, a pre-operative evaluation is first performed, where patients are evaluated in every aspect to determine whether or not they are suitable for the procedure. After confirming the suitability of the patients for the Gastric sleeve surgery, the following steps are followed.

  • ANESTHESIA
    The surgery is performed under general anesthesia. Patients are put under anesthesia with the medication previously determined during the anesthesia examination.
  • OPEN INCISIONS
    If the patient’s state of health permits, the minimally invasive method (laparoscopic surgery) is preferred for the operation. In this method, 4-5 incisions are made in the abdominal area with an average size of 1 cm.

INCISIONS AND CAMERA USE

A camera is inserted into the relevant area from one of the incisions made in order to obtain images of the abdominal cavity. The recorded images are transmitted to the screen in the operating room. Medical instruments are inserted into the relevant field from the other incisions.

REMOVAL OF A PART OF THE STOMACH


The aim of the procedure is to remove 80% of the stomach. However, the stomach is calibrated with a special tube before this procedure in order to avoid bottlenecks and blockages in later stages. The calibration tube is placed on the right side of the stomach and the section to be removed is determined in this way. The left part of the stomach is separated at the points determined with the tube and removed outwards. This procedure is performed using a device called a stapler.

FORMATION OF THE STOMACH POUCH


A new stomach (or stomach pouch) is formed at the site defined by the tube. The stapler connects the cut portion of the stomach to a medical stapler, creating a new tubular stomach. The formation of the stomach pouch is one of the most important and critical steps of this procedure. The newly created stomach pouch has entrances and exits like the old stomach. No further work is done on these areas.

CONTROL

One of the most important risks in Gastric sleeve surgery is the occurrence of leaks in the stapler line. For this reason, necessary checks are carried out before the operation is completed. The leakage is checked both with a special liquid and with pressure. During the checks, if any leaks are detected, the necessary corrections are made at this point. If no leaks are detected during the checks, the procedure is completed by applying a special tissue adhesive solution to the connected tissues in the stomach. Thanks to the tissue adhesive, the risk of leakage is reduced to very low levels.

These are the phases and steps of Gastric sleeve surgery in general terms. The steps involved are essentially much more detailed and sensitive processes. To perform these processes successfully, a surgeon who is an expert in his field and a clinic with high medical expertise must be preferred.

NUTRITION AND WEIGHT LOSS AFTER Gastric sleeve surgery:


The period following Gastric sleeve surgery is also of great importance. In this process, patients should start with a clear liquid diet. This should be followed by a gradual transition to a liquid, puree, granular, soft food diet before finally resuming a normal diet.

After surgery, patients are expected to lose an average of 8-10 kg in the first month and an average of 4-6 kg in the following months. Strict adherence to the prepared diet and exercise program is crucial for this.
