Intragastric balloon or diet alone? A retrospective evaluation

Area of Science:

• Bariatric Surgery
• Weight Management
• Gastroenterology

Background:

• Limited long-term data exists for the BioEnterics Intragastric Balloon (BIB).
• This study retrospectively compares BIB placement outcomes against diet-only regimens.

Purpose of the Study:

• To evaluate the efficacy of BIB versus diet alone for weight loss.
• To compare weight loss parameters and comorbidity changes at 6 and 24 months.

Main Methods:

• Retrospective analysis of 130 patients with BIB and 130 diet-only patients (2005-2006).
• Diet group received a 1000-1200 calorie Mediterranean diet; BIB group received counseling.
• Weight loss (kg, %EWL, BMI, %EBL) and comorbidities assessed at 6 and 24 months.

Main Results:

• At 6 months, BIB significantly outperformed diet in weight loss (kg, %EWL, %EBL) and BMI reduction.
• Patient dropout was significantly lower in the BIB group (0.7% vs. 19.2%) at 24 months.
• BIB patients showed weight regain tendency by 24 months, while diet patients regained most lost weight.

Conclusions:

• The BioEnterics Intragastric Balloon (BIB) demonstrates superior short-to-medium term weight loss efficacy compared to diet alone.
• Despite some weight regain by 24 months, BIB offers significant advantages over diet-only interventions.
• The retrospective design is a limitation, but findings support BIB's effectiveness for initial weight reduction.
