Gastric Emptying After Sleeve Gastrectomy

Summary

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.
