Comparison of Surgical Outcomes between a 12-Month Adjustable Intragastric Balloon Placement versus Laparoscopic Sleeve Gastrectomy in Class I-II Obesity: A Retrospective Study
Main Article Content
Abstract
Objective: To compare weight loss between intragastric balloon (IGB) and laparoscopic sleeve gastrectomy (LSG) in patients with class I-II obesity.
Materials and Methods: The authors retrospectively reviewed data of obese patients with a body mass index (BMI) of 30-40 kg/m2 who underwent LSG or IGB in Vajira hospital from January 2012 to December 2017. The primary outcome was percent excess weight loss (%EWL), and secondary outcomes were improvement in co-morbidities, rate of complications, and changes in quality of life at 12 months after procedures.
Results: Sixteen patients who underwent either LSG (n = 9) or IGB (n = 7) were enrolled. There were no significant differences in baseline characteristics except co-morbidity status. The median (interquartile range) %EWL following LSG and IGB placement was 67.8 (61.3, 81) and 20.5 (2.5, 34), respectively, at 12 months (p-value = 0.001). Most co-morbidities were improved or resolved after LSG, but none of them was improved after IGB placement. Complications and quality of life were not significantly different following either intervention.
Conclusion: Results suggest that LSG may be more suitable than IGB placement for patients with class I–II obesity in terms of both weight loss.
