Gastric Sleeve Procedure
Also known as "Vertical Sleeve Gastrectomy (VSG)", gastric sleeve surgery is a technique that drastically reduces the size of the stomach by giving it the shape of a stomach. a cylinder, about the size and shape of a banana. In most VSG procedures, about 85% of the total volume of the stomach is removed, making a stomach with a remaining capacity of 60 to 100 ml.
Almost as with gastric bypass, this technique promotes weight loss by limiting dietary intake. The difference is that this technique does not reroute the small intestine, the nerves of the stomach remain intact, while the hormones related to the feeling of hunger are radically inhibited.
Although gastric sleeve surgery has less research evidence supporting its efficacy, it is becoming increasingly popular in patients with a BMI of less than 37, or for whom traditional gastric bypass surgery has proven ineffective.
Although both gastric bypass and gastric sleeve consist in part of the reduction of stomach volume, these are two different techniques, and it is this difference that could determine whether a patient can benefit from one or the other surgery. The biggest difference is that gastric sleeve surgery is not based on the malabsorption of nutrients for weight loss because there is no food rerouting.
On the other hand, gastric bypass surgery can expose patients to the risk of diseases such as osteoporosis, anemia and protein and vitamin deficiency. Therefore, patients undergoing gastric bypass surgery must pay more attention to what they eat and must also regularly take vitamin and mineral supplements. In addition to the differences of malabsorption.
Gastric sleeve surgery inhibits the hormone that stimulates the sensation of hunger, called "ghrelin".
The entrance and exit doors of the cardia and pylorus stomach remain intact and unaltered.
The duration of surgery of the gastric sleeve is 40 to 60 minutes.
It can be performed on high-risk patients, including those who have had previous surgeries.
Since one does not touch the patient's pylorus, the patient is not likely to catch the hunting syndrome.
