In the digestive system, the stomach is in the form of a pouch so that it can receive and store more nutrients. They surgically remove most of the stomach irreversibly. Gastric sleeve surgery is the continuation of the esophagus and making it a system that continues with the intestines. They complete the surgery without placing a tube or other foreign body in the stomach.

Gastric surgery does not only shrink the stomach.  While shrinking the stomach, they take most of the area where the hormone that provides hunger hormone is located. The patient feels less hunger. For this reason, sleeve gastrectomy surgery creates not only a mechanical effect but also a hormonal effect. There are also some details about what is a gastric sleeve procedure question.

In order not to make a mistake during the surgery and not to make the stomach too small, a calibration tube is placed at the stomach entrance as big as the diameter of the esophagus. Thanks to this calibration tube, they make the stomach smaller as if it were a continuation of the esophagus. Thus, they prevent excessive narrowness and clogging. After taking precautions regarding vascularization and bleeding, they cut the stomach from length with special cutting and closing tools (stapling).

What Should Patients Pay Attention Before and After Stomach Surgery?

We answered the question of what is a gastric sleeve procedure, but we should also look at what are the surgical procedures. Before sleeve gastrectomy surgery, patients undergo extensive tests. Surgeons evaluate whether patients have problems such as stomach ulcers and heart disease that may prevent gastric surgery. First of all, they eliminate the problems that prevent surgery and make the patient suitable for surgery. Sometimes these treatments applied before surgery can last for months. In addition, dietitians, psychology and psychiatrists additionally test the affected person and examine whether or not he’s appropriate for surgery. The important thing is that the patient enters the bariatric surgery without any problems.

Patients with very serious weight problems and especially those with fatty liver can apply a special diet program for 10-15 days before the operation. With this special diet program, they aim to shrink the liver. They also make the surgery risk-free.

It is a more appropriate way to calculate based on body mass index (BMI) rather than excess weight when deciding on the surgical procedure for bariatric surgeries including sleeve gastrectomy. They find the body mass index by dividing the patient’s weight in kg by the patient’s height in meters squared.

People with a BMI of 25-30 are not obese. This group is overweight. However, people with a body mass index of 30 and above are obese. Not all obese patients are suitable for sleeve gastrectomy or other bariatric surgery. Patients with a body mass index of 35 and above and who experience the diseases and diseases brought about by obesity are suitable for sleeve gastrectomy surgery. Even if patients with a body mass index of 40 and above do not have any discomfort, it is suitable for sleeve gastrectomy and other obesity surgeries.

Uncontrolled diabetes is the exception in these calculations.If the patient’s diabetes cannot be controlled despite all diet and medical treatment attempts, the patient is suitable for metabolic surgery even if the body mass index is between 30-35.
