The Gastric Sleeve is a surgery which allows to reduce the capacity of the stomach and leave it in approximately 30%, sectioning a part of it. In other words it involves cutting about two thirds of the stomach to make it much smaller.


The gastric sleeve not only works by reducing gastric capacity,
It also helps weight loss due to the decrease in a hormone which is produced in the stomach called ghrelin, thus decreasing the feeling of hunger and anxiety by eating.

It is a procedure that is performed by laparoscopy or minimal invasion, does not alter at all the physiology of the stomach and is a procedure that can be performed both in patients with high BMI (greater than 35) and in patients with lower BMI such as 30-35.


The sleeve has advantages over other procedures Bariatric:
• It does not require disconnecting and reconnecting the intestines.
• It is a technically simpler operation than the Gastric Bypass.
• It reduces the capacity of the stomach.
• A portion of the stomach is removed that produces a hormone that stimulates hunger (Ghrelin).
• Rapid emptying syndrome is rare to occur, possibly occurring in the first few
Weeks, but is resolved later because the part of the stomach called pylorus is preserved.
• It decreases the risk of developing an ulcer.
• By avoiding the intestinal bridge, intestinal obstruction, anemia, lack of protein and vitamin deficiencies are also avoided, presenting minimal risk.
• It can be used as the first treatment in patients with Super Morbid Obesity requiring a Gastrojejunal Bypass.
• The recovery is very fast, it only requires 2 or 3 days of hospitalization and the re-labor start can be carried out from 7 to 8 days.


• It is a surgery therefore it is irreversible.
• There may be re-gain of weight if the patient does not carry a proper diet and exercise plan.
• Another problem, if the patient continues with improper eating habits, his stomach can increase his gastric capacity again.


• High-risk patients.
• Patients with BMI> 40 or> 35 with comorbidity.
• Patients in whom the bypass (gastrojejunal shunt) is contraindicated may be the case of patients with inflammatory bowel diseases or severe adhesions of the small intestine.
