Gastric Sleeve and Nissen Sleeve

Mode of action: sleeve or vertical gastroplasty in Tunisia.

​

The sleeve consists of removing a large part of the stomach to form a tube. The food will first be slowed down during its passage through the tube, then be evacuated very quickly into the small intestine.

​

The Sleeve acts through several mechanisms that combine:

​

• A restriction (such as gastroplasty).

• A decrease in the level of grelin, which is the hunger hormone, which leads to a lack of interest in food.

​

The selection criteria are rigorous, it is not necessary to have a BMI greater than 40 to be operated on in Tunisia. We treat patients with a BMI of 30.

Result of a Sleeve in Tunisia

A Sleeve allows you to lose about forty kilos in one year. Namely a loss of 70% of excess weight. If it turns out to be insufficient to obtain greater weight loss, it can then be transformed into a bypass under good safety conditions.

​

Currently, some teams offer the Sleeve instead of gastroplasty (gastric banding) for the following reasons:

​

• It causes a rapid feeling of satiety, like gastroplasty.

• It does not require the placement of a foreign body (gastric band).

• Vomiting is less common than with gastroplasty.

• It decreases the level of ghrelin, and therefore the feeling of hunger, as in the bypass.

• It is performed by laparoscopy
