The balloon is folded on itself within a sleeve that opens when filled and is attached
to the distal end of the feeding channel.
This sleeve, which protects the ball and facilitates its placement, is attached to the introduction channel, through which the guide wire passes.
The probe that allows the balloon to be implanted in the gastric cavity of the patient has a double lumen.
One of the lumens acts as a feeding channel for the balloon once the stylet has been removed, which must be in place during the insertion maneuver, and the other allows the guide wire, previously inserted endoscopically, to slide inside and guide the Stella device into the patient, without errors, with smoothness and speed.
The procedure tends to take a shorter duration than that of conventional balloons given the ease of insertion thanks to the double lumen probe and the guide wire.
The duration of treatment is approximately 6 months, after which the balloon must be removed, with an expected weight loss in average about 14,5 Kg*.
*Mean weight loss derived from a multicenter clinical trial performed in 2022-2023 (N=69).
Implantation of the endogastric balloon
The intervention is carried out within a multidisciplinary program, integrating endoscopists, psychologists and nutritionists to guarantee success and results in the short and long term.
The procedure, that can be done in the endoscopy room with sedation, tends to take a shorter duration than that of conventional balloons given the ease of insertion of the balloon thanks to the double lumen probe and the guide wire.
1.
Previous examination of the gastric cavity using and introduction of the guide wire up to the beginning of the duodenum-
2.
Removal of the endoscope and introduction of the Stella device through the guide wire into the gastric cavity.
3.
Removal of the stylet, insertion of the endoscope and filling the ball.
4.
Extraction of the guide wire and the catheter releasing the balloon into the gastric cavity and endoscopic examination and removal of the endoscope.
Filling volume
The balloon achieves as it works by filling the stomach, causing a feeling of satiety.
400
Minimum
700
Maximum
Indicated for overweight or obese adults who have failed with previous diets and require a physical aid that increases the feeling of satiety to reduce the amount of intake.
Patients with BMI between 27.0 and 34.9 kg/m² (with at least 1 obesity-related comorbidity
for those with BMI between 27.0 and 29.9 kg/m2).
Patients with BMI between 35.0 and 39.9 kg/m² provided they do not have more
than 3 major comorbidities associated with obesity.
