Gastric ring

The silicone ring is a ring corresponding to a pneumatic tire that will transform the hourglass stomach.

Foods will stagnate over the small stomach and this is what will lead to satiety;

This ring is connected to a housing accessible subcutaneous injection which allows the serum tighten or loosen it.

This is an intervention that can reduce reverscible 50% excess weight within 12 to 18 months.

The term reversible is revised downward because the ring ablation is more difficult than laying. !

It is aimed perfectly to patients under 35 years with a BMI less than 35.

The disadvantage is: inéficacité in his big eaters of liquid sugars (ice cream, chocolates, sweetened juices). This drawback is overtaken by awareness.

Our team has put over 1300 rings with an average length of stay of one day and an operation lasting less than 30 minutes.

Average duration of the intervention² 30 minutes
Mean duration of hospitalization³ 1 day
Mortality intervention 0.1%
Principal risks of complications Mechanical complications may occur after surgery, even after several years
