Role of ultrasound in the detection and management of complications of swallowable intragastric balloons for obesity: a report of two cases

In the context of the various management options available for obesity, intragastric balloons (IGBs) represent a solution for patients at high surgical risk. Swallowable IGBs are devices that can be ingested orally and then inflated within the stomach to aid in weight loss. Although generally well tolerated, these devices may migrate and cause gastrointestinal obstructive symptoms. Here we report on two cases where these obstructive complications of swallowable IGBs were promptly and non-invasively diagnosed with ultrasonography (US), which also permitted conservative management via US-guided percutaneous aspiration of the impacted balloons. These cases demonstrate that the US may provide a rapid and effective tool for managing IGBs migration, potentially reducing the need for surgical intervention.
