sleeve Gastric, also known as sleeve gastrectomy or sleeve gastrectomy, is a type of bariatric surgery that is performed with the objective of treating morbid obesity, consisting in the removal of the left part of the stomach, which causes a decrease in the capacity of the stomach. stomach to store food. Thus, this surgery can lead to a loss of up to 40% of the initial weight.
This surgery is indicated for the treatment of obesity when the use of other, more natural forms has not shown any results even after 2 years or when the person already has a BMI greater than 50 kg/m². In addition, it can also be performed in patients with a BMI of 35 kg/m² but who also have heart, respiratory or decompensated diabetes, for example.
How is the surgery done
the surgery of sleeve gastric is performed under general anesthesia and lasts, on average, 2 hours. However, it is common for the person to stay in hospital for at least 3 days.
Generally, this surgery is performed by videolaparoscopy, in which small holes are made in the abdomen, through which tubes and instruments are inserted to make small cuts in the stomach, without having to make a large cut in the skin.
During surgery, the doctor makes a vertical cut, cutting the left part of the stomach and leaving the organ in the shape of a tube or sleeve, similar to a banana. In this surgery, up to 85% of the stomach is removed, making it smaller and causing the person to eat less.
The main advantages of sleeve gastric, in relation to other types of bariatric surgery are:
- Take between 50 to 150 ml of food, instead of 1 L, which is the usual pattern before surgery;
- Greater weight loss than that obtained with the adjustable gastric band, without the need for band adjustments;
- Turn gastrectomy into bypass gastric, if necessary;
- The intestine is unchanged, with the normal absorption of important nutrients taking place.
It is still a technically simpler surgery than the bypass gastric, allowing weight loss over several years and with less risk of complications.
However, despite all the advantages, it remains a very aggressive technique for the body and cannot be reversed, unlike other simpler forms of surgery, such as placing a gastric band or a balloon.
O sleeve gastric can cause nausea, vomiting and heartburn. However, the most serious complications of this surgery include the appearance of a fistula, which is an abnormal connection between the stomach and the abdominal cavity, which can increase the chances of infections. In such cases, further surgery may be necessary.
How is recovery
Recovery from surgery can take between 6 months to 1 year, with gradual weight loss, requiring lifestyle changes.
Thus, the person who underwent gastrectomy must follow the guidelines:
- diet indicated by the nutritionist.
