The Efficacy Comparison of Endoscopic Bariatric Therapies: 6-Month Versus 12-Month Intragastric Balloon Versus Endoscopic Sleeve Gastroplasty

Abstract

Introduction: Intragastric balloon (IGB) insertion and endoscopic sleeve gastroplasty (ESG) are known to be effective and safe in achieving weight loss. The aim of this study was to compare the effects of a 6-month IGB therapy, a 12-month IGB therapy, and ESG. Methods: We retrospectively analyzed the weight loss at IGB (Orbera) removal after 6 months (124 patients), at IGB (Orbera365) removal after 12 months (61 patients) and at 6 and 12 months after ESG (42 and 34 patients, respectively). Postprocedural care, including medication and diet, was the same for all procedures. Results: Mean TBWL in patients undergoing IGB placement for 6 and 12 months and ESG after 6 and 12 months were 15.2, 15.8, 26.5, and 28.7 kg, respectively. There was no significant difference in the mean %TBWL in patients undergoing IGB placement for 6 or for 12 months (15.3% vs. 14.7%, P = 0.7). ESG patients showed a significantly higher mean %TBWL than IGB patients after 6 months (15.3 vs. 19.8, P = 0.005) and 12 months (14.7 vs. 22.5, P < 0.001). Conclusion: All three studied methods were effective for achieving weight loss. However, there was no significant difference between 6-month and 12-month IGB therapies outcomes. ESG appeared to be a more effective obesity treatment modality than IGB. Graphical Abstract: [Figure not available: see fulltext.]
