Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
