Brief Summary

Endoscopic sleeve gastroplasty (ESG) is a transoral endoscopic procedure that creates a tubular sleeve along the lesser curvature with a gastric volume of approximately 30%. Summarizing the available literature published since its introduction in 2013, ESG was capable to achieve \> 10% of sustained total body weight loss in a majority of mildly to moderately obese patients with the caveat of only minor adverse events. Besides weight loss, little is known about the metabolic effects of ESG. The present study seeks to measure markers of glucose homeostasis during oral glucose tolerance tests before and subsequently after application of ESG in 12 patients.

Outcome Measures

Primary Outcomes (1)

  • Area under the curve for plasma glucose in oral glucose tolerance test

    Plasma glucose will be measured in oral glucose tolerance test following dapagliflozin and will be compared with concentrations measured following placebo. Active and inactivated glucagon like peptide I will be measured.

    From time-point 0 to 120 minutes during oral glucose tolerance test, measurement every 15 minutes

Secondary Outcomes (6)

  • Area under the curve for glucagon-like peptide I in oral glucose tolerance test

    From time-point 0 to 120 minutes during oral glucose tolerance test, measurement every 15 minutes

  • Area under the curve for gastric inhibitory peptide in oral glucose tolerance test

    From time-point 0 to 120 minutes during oral glucose tolerance test, measurement every 15 minutes

  • Area under the curve for glucagon in oral glucose tolerance test

    From time-point 0 to 120 minutes during oral glucose tolerance test, measurement every 15 minutes

  • Area under the curve for somatostatin in oral glucose tolerance test

    From time-point 0 to 120 minutes during oral glucose tolerance test, measurement every 15 minutes

  • Area under the curve for non-acyl ghrelin in oral glucose tolerance test

    From time-point 0 to 120 minutes during oral glucose tolerance test, measurement every 15 minutes

  • +1 more secondary outcomes
