The purpose of this study is to determine the correlation between the SmartPill diagnostic capsule and gastric scintigraphy to determining Gastric Residence Time.

Condition	Intervention
Digestive System Diseases Gastrointestinal Diseases Stomach Diseases Gastroparesis	Device: SmartPill Diagnostics, Inc. ACT GI Monitoring System

Further Study Details: 

Primary Outcomes: To demonstrate the correlation between the gastric residence time as determined by SmartPill GI Monitoring System and the gastric emptying time of a radiolabeled meal in both healthy subjects and patients with documented gastroparesis.
Secondary Outcomes: · To demonstrate that the gastric residence time as determined by SmartPill GI Monitoring System can discriminate between healthy human subjects and patients with gastroparesis.; · To characterize pressure patterns within the antrum and duodenum in healthy subjects and patients with documented gastroparesis.; · To characterize total GI transit time in healthy subjects
Expected Total Enrollment:  130

Gastric emptying scintigraphy is considered the gold standard for evaluating gastric emptying and is widely available. Accurate characterization of gastric emptying may guide medical and surgical treatment choices. In addition, these techniques may allow for monitoring of therapeutic results for follow-up patient management.

The SmartPill GI Monitoring System offers an alternative non-invasive method for characterizing disorders of the stomach. The system consists of an ingestible capsule that houses sensors for pH, temperature, and pressure, a receiver for receiving and storing signals from the capsule, and software for displaying data on a personal computer. The capsule samples at regular intervals and transmits the sensed pH, pressure, and temperature data to a portable receiver worn by the subject. After test completion, the recorded data is downloaded to a personal computer for subsequent evaluation.
