Simultaneous Blood Glucose Monitoring During Gastric-Emptying Scintigraphy May Identify Unsuspected Abnormalities

Purpose A retrospective study of 197 patients was performed to evaluate utility of simultaneous fingerstick glucose monitoring during standardized solid meal gastric-emptying scintigraphy (GES). We hypothesized the unlabeled carbohydrate components of the standardized meal often empty at different rates than the labeled egg protein component and that simultaneous glucose monitoring may identify rapid carbohydrate gastric emptying. Methods Patients were classified as normal, rapid, or delayed gastric emptying from the standardized solid egg meal GES criteria. Further subcategorization was made based on postprandial glycemic excursions above baseline at 30/60 minutes and was delineated as elevated (>75 mg/>85 mg/dL), normal, or diminished (
