Abstract:

Aim: To compare the effects of endoscopic intragastric balloon (IGB) placement and intragastric botulinum toxin-A (BTX-A) injection in terms of weight loss among patients with non-morbid obesity. Methods: This retrospective single center study was conducted between 01.08.2020 and 01.01.2022. A total of 39 patients with a body mass index (BMI) of <40 without comorbidities were included in the study. Nineteen underwent intragastric BTX-A injection and 20 underwent IGB placement. Patients were evaluated 1 month and 6 months after the procedures. Results: Mean age was 39.4 ± 8.6 in the BTX-A group and 37.3 ± 10.4 in the IGB group (p = 0.496). 78.9% of the BTX-A group and 75.0% of the IGB group were female (p = 1.000). In both groups, the median weight 1 month after the procedure was significantly lower than before the procedure, and the median weight 6 months after the procedure was significantly lower than 1 month after the procedure (p<0.001 for both groups). The median weight loss in the IGB group at both the 1st and 6th months was significantly greater than the corresponding values of the BTX-A group (p < 0.001 for both). Conclusion: IGB insertion appears to be a more successful endoscopic bariatric procedure than intragastric BTX-A injection, as measured by weight loss at post-intervention 1 month and 6 months. IGB may be preferred in patients with a BMI below 40 without obesity-related comorbidity.
