Endoscopic sleeve gastroplasty and gastric sleeve: What’s the difference?
How patients are considered eligible
In order to be eligible for
gastric sleeve, patients should have a BMI higher than 40. Individuals with a BMI higher than 35 may also be eligible if there are other conditions related to obesity. You can calculate your
BMI here Ideal candidates for an
endoscopic sleeve gastroplasty have a BMI higher than 27. ESG may also be recommended to individuals with higher BMI who need to lose some weight before undergoing bariatric surgery (e.g. gastric sleeve).
How the surgeon treats the stomach
While both procedures aim to make your stomach smaller, they work in two completely different ways. During a gastric sleeve, the surgeon will remove around two thirds of your stomach. This means that gastric sleeve surgery is irreversible. On the other hand, endoscopic sleeve gastroplasty works by stitching the stomach walls together from the inside. No parts of the stomach are removed. This procedure is reversible as
the doctor can remove the non-absorbable stitches placed within a certain timeframe.
How surgery is performed
Gastric sleeve surgery is performed using a laparoscopic technique; endoscopic sleeve gastroplasty is performed endoscopically. Let’s have a look at how these two procedures differ. Laparoscopy: The surgeon creates a few small incisions in the abdomen to access the stomach. A laparoscope is used to perform the procedure; thanks to the tiny camera attached, the surgeon is able to view the organs in the abdomen and perform surgery. Laparoscopy is more invasive than endoscopy. Endoscopy: This is a nonsurgical procedure used to inspect a patient’s digestive tract. The doctor uses an endoscope that carries a camera and a suturing device to perform the procedure. The endoscope is inserted in the mouth of the patient until it reaches theirstomach.
