Background
Obesity is a major risk factor for several chronic diseases. The BioEnterics® Intragastric Balloon (BIB®) is used worldwide as a short-term (6 months) treatment in morbid obese patients. However, removal of BIB® past 6 months is a common occurrence in clinical practice often as a result of patient factors. The aim of the present Italian multicentre cohort study was to evaluate the safety and efficacy of the BIB® left in situ for more than 6 months.
Materials and methods
A total of eight Italian centres participated in the study. Participating centres received a standardised questionnaire designed to capture safety and efficacy data. Weight loss data, as well as date, and reason for removal of the BIB® after 6 months were recorded. Adverse events, including mortality and complications, operators’ subjective technical notes and findings, and difficulties during removal procedure were also collected.
Results
Six hundred and eleven patients were included. In the majority of cases, patient extended BIB® treatment due to satisfactory weight loss (44 %). At 6 months, all patients achieved a BMI statistically lower than the initial BMI (p < 0.001). There was a non-significant trend towards greater BMIL % in patients who underwent removal up to 15 months versus the results achieved up to 6 months. No major complications were recorded.
Conclusion
Extending the duration of BIB® use up to 14 months safely maintains weight loss and satiety with greater results than that up to 6 months, without complications.
