In recent years, there has been a significant increase in both obesity cases and the demand for bariatric surgery in our country and worldwide. Gastric sleeve gastrectomy is a surgical procedure in which the most expanding, stretching and appetite-managing part of the stomach is removed. The aim of the operation is to reduce the amount of food intake by reducing the volume of the stomach. On the other hand, it is a highly effective surgical procedure for appetite control and satiety due to the Ghrelin hormone secreted by the removed part of the stomach.
What is Gastric Sleeve Gastrectomy?
Sleeve gastrectomy, also known as stomach reduction surgery, is a surgical procedure used in the treatment of obesity. The surgery, which is performed on the basis of laparoscopic cutting and removal of approximately 80% of the stomach with the closed surgery method, enables the patient to gain the habit of eating less food and reduce food absorption.
After the operation, the weight loss process starts with a decrease in the patient's appetite. At the same time, insulin resistance also decreases. It may also be possible to apply the surgery as a transitional surgery for patients with obesity classified as advanced obesity. In this context, it may be applied as the first step to making advanced obesity patients ready for bypass group surgeries.
How is sleeve gastrectomy surgery performed?
Gastric sleeve gastrectomy is performed under general anaesthesia and usually by laparoscopic method. The decision to be performed through a single hole, 4-5 holes, or with a robot is made specifically for the patient.
In order to avoid any problems during the operation and not to reduce the stomach more than necessary, a calibration tube up to the diameter of the oesophagus is placed in the stomach entrance and the stomach is reduced as if it is a continuation of the oesophagus. In addition, the risk of excessive stenosis and obstruction is prevented. After the stomach is cut through using special cutting and closing tools and the procedure is completed, the calibration tube is removed and tests are performed to see if any leakage occurs.
In Which Diseases Is Gastric Sleeve Gastrectomy Used?
Many diseases including type 2 diabetes, sleep apnea, high blood pressure, and joint disorders accompanying morbid obesity benefit from sleeve gastrectomy, which is primarily a treatment for morbid obesity.
Frequently Asked Questions
Which Patients Are Suitable for Gastric Sleeve Gastrectomy?
- Morbidly obese,
- Unable to lose weight with regular diet and exercise,
- Those with a body mass index of 40 and above or with a body mass index between 35 and 40 but with health problems such as sleep apnoea, type 2 diabetes, and hypertension due to being overweight,
- It is a procedure suitable for people who do not have a health problem that prevents them from undergoing surgery.
What should be considered before and during sleeve gastrectomy surgery?
Smoking should be stopped or reduced as much as possible before the surgery. This is because smoking has a risk of adversely affecting the healing process after surgery. It also increases the risk of secretion, sore throat, and cough after anesthesia. Before the operation, a body analysis is performed and an appropriate nutrition program is determined for the patient. Necessary tests are performed and vitamin and mineral values are analysed. The general health status is also assessed. The psychological state of the patient is also subjected to the evaluation process by experts.
Are there any age and weight limits for sleeve gastrectomy?
The surgery can be applied to people between the ages of 18 and 65. The patient should be obese for at least 3 years, and the desired results should not be achieved with a regular diet and sports. In addition, there should be problems such as type 2 diabetes, sleep apnoea, and hypertension caused by obesity, although the body mass index is 40 and above or the body mass index is between 35 and 40. Although it is a treatment generally recommended for middle-aged people, it can be applied to younger or older patients by making a patient-specific suitability assessment.
