AIM: Our aim is to demonstrate the feasibility of real-time ultrasound-assisted insertion of the Elipse® intragastric balloon for the treatment of overweight and obese patients.
METHODS: A plastic gastric phantom filled with water was created to mimic the gastric lumen and to test the operator's ability to recognize the capsule containing the balloon inside. In the clinical phase, we tested the operator's ability to recognize the swallowed capsule and its progressive filling in the gastric lumen by means of ultrasound in 36 consecutive patients with a mean body mass index of 35 in an outpatient setting.
RESULTS: The ultrasound hyperechoic signal of the capsule in the gastric lumen was visible early on and was confirmed after the injection of a few milliliters of saline solution in the capsule with a cyst-like shape. The insertion of the balloon was successful in all cases at the first attempt, and the complete filling was monitored in real-time without the need for fluoroscopy. Postprocedure symptoms were limited to the first 24-48 h and were controlled by symptomatic therapy; endoscopic removal of the balloon because of painful distal gastric migration was necessary in one case after 3 months.
CONCLUSION: After a learning curve, we were able to demonstrate the placement of the balloon capsule inside the fundus of the stomach under ultrasound guidance without fluoroscopy in all patients in an outpatient setting.
