Abstrakt: Purpose: The main purpose of this systematic review was to reflect on recent literature on bariatric LGA embolization for obesity treatment and to compare this new procedure in human and animal studies.
Methods: A systematic search of Scopus, MEDLINE, Web of Science, Embase, and Google Scholar was performed to identify human and animal studies employing bariatric LGA embolization to treat obesity. As well, Cochrane's Q test and the I 2 statistic were utilized to determine heterogeneity.
Results: Nine human and four animal studies recruiting a total of 118 cases (n = 78 patients and n = 40 animals) were included in analysis. All assessments on body mass index (BMI), weight, and ghrelin levels had been fulfilled based on before-after (human studies) and intervention-control designs (animal studies) using bariatric LGA embolization. The findings suggested that bariatric LGA embolization had significantly decreased BMI (mean difference (MD): - 2.66, 95% confidence interval [CI] - 3.74, - 1.58, P < 0.001) and weight (MD: - 8.69, 95% CI - 10.48, - 6.89, P < 0.001) in humans. Although overall pooled estimate showed no significant changes in ghrelin levels following this procedure (Hedges' g statistic: - 0.91, 95% CI - 1.83, 0.01, P = 0.05) in humans, a significant reduction was observed in animal studies (MD: - 756.56, 95% CI - 1098.79, - 414.33, P < 0.001) along with a significant drop in weight (MD: - 7.64, 95% CI - 13.73, - 1.54, P < 0.001).
Conclusion: The present study concluded that ghrelin levels in humans had not been affected, although bariatric LGA embolization might significantly improve BMI and weight.
