An observational study in Gastric Emptying and Bariatric Surgery, sponsored by Rijnstate Hospital. Completed at 1 site in Netherlands. Open to female participants aged 18 Years to 55 Years. Per ClinicalTrials.gov, last updated 2026-04-03.

Sleeve gastrectomy (SG) increases gastrointestinal motility, which influences feelings of fullness and satiety. By understanding the differences in gastric emptying (GE) between patients with sufficient weight loss (Total weight loss [TWL] > 35%) and insufficient weight loss (TWL \< 25%), better insight in the aetiology of weight loss after sleeve gastrectomy may be obtained. GE will be measured with scintigraphy and MRI.
Sleeve gastrectomy (SG) increases gastrointestinal motility, which influences feelings of fullness and satiety. Patients' weight loss response on SG varies widely and is difficult to predict. By understanding the differences in gastric emptying (GE) between patients with sufficient weight loss (Total weight loss [TWL] > 35%) and insufficient weight loss (TWL \< 25%), better insight in the aetiology of weight loss after sleeve gastrectomy may be obtained. GE will be measured with scintigraphy and MRI. MRI is a non-invasive imaging method which provides more detailed images of the SG compared to the conventionally used scintigraphy scans.
Rijnstate Hospital is the lead sponsor of 127 studies on the registry; 14 are open to participants now.
