Intragastric balloons (IGBs) are widely used as a minimally invasive weight loss intervention for patients with obesity. While the recommended implantation period for most IGBs is 6 to 12 months, exceeding this duration is associated with an increased risk of complications such as deflation, migration, obstruction, and gastric perforation.

Initially implanted for obesity management with a body mass index (BMI) of 38 kg/m
