Adjustable intragastric balloons: a 12-month pilot trial in endoscopic weight loss management.

Intragastric balloons are associated with (1) early period intolerance, (2) diminished effect within 3-4 months, and (3) bowel obstruction risk mandating removal at 6 months. The introduction of an adjustable balloon could improve comfort and offer greater efficacy. A migration prevention function, safely enabling prolonged implantation, could improve efficacy and weight maintenance post-extraction.
