Type
Pure Restrictive Mechanism of action

Reduction of meal volume (early Fullness)

Hormonal effect : Decreased Ghrelin Hormone

Expected Weight Loss
60 – 70% of the excess weight Brief Description
Stomach is divided longitudinally using GIA Stapler (a device that will cut and seal the edges at the same time), significant part of the stomach will be removed. The new stomach is tailored to be a tube like (Sleeve shaped) stomach. Sleeve gastrectomy is the most widely used and safest surgery.

Type

Malabsorptive

Mild restrictive

Mechanism of action

Reduction of nutrients absorption from the food

Mild early Satiety

Hormonal Effect – Increase GLP1

Expected Weight Loss
70% of excess weight Brief Description
A narrow long stomach tube is created by GIA stapler (a device that will cut and seal the edges at the same time), – The stomach is kept in the body. Then this stomach tube is joined to a point in the small bowel lies about 1.5 m away from the beginning of the small bowel. Doing this will make the passage of the food bypassing the stomach and the first part of the small bowel.

Type
Restrictive Mild Malabsorptive Mechanism of action

Reduce the meal size (Early Satiety)

Mild Reduction of nutrients absorption from the food

Hormonal Effect – Increase GLP1

Expected Weight Loss
70% of excess weight Brief Description
A very small pouch of the upper part of the stomach is created (Separated) using GIA stapler (a device that will cut and seal the edges at the same time), The small bowel is divided at a point 50-60 cm distal to the beginning of it. That will create a proximal and a distal end. The distal end is joined (Anastomosed) to the small stomach pouch. And the proximal end is rejoined to the small bowel but 1.5 m away from the previous small bowel stomach join. Doing this will Reduce the meal volume and induce early satiety and make the food passage bypassing the stomach and the first part of the small bowel to reduce the absorption of nutrients from food.
