Gastrointestinal Motility, Part 1: Esophageal Transit and Gastric Emptying

Although not as well standardized as gastric emptying (GE) scintigraphy, esophageal transit scintigraphy, if performed in a comprehensive manner including both quantitative and qualitative analysis of single- and multiple-swallow studies, is clinically useful when expertise in esophageal manometry is not available or not tolerated and when esophageal manometry or barium videofluoroscopy results are equivocal or nondiagnostic. GE scintigraphy has undergone much-needed standardization. Both solid and liquid GE studies play an important role in assessing patients with upper gastrointestinal symptoms. Because measurement of simple total GE is often not sufficient to explain patient symptoms, there is a need to expand the analysis of GE scintigraphy to include the separate roles of the fundus and antrum and to include the complex interactions the stomach has with other organ systems.
