Ingestible pH and Pressure Capsule

DESCRIPTION

An ingestible pH and pressure-sensing capsule (e.g., SmartPill GI Monitoring System) measures pH, pressure, and temperature changes to signify the passage of the capsule through portions of the gastrointestinal tract. It is proposed as a means of evaluating gastric emptying for the diagnosis of gastroparesis, and colonic transit times for the diagnosis of slow transit constipation.

Once ingested, the device transmits data to an external receiver. Gastric emptying is signaled when the pH monitor in the capsule indicates a change in pH from the acidic environment of the stomach to the alkaline environment of the small intestine. The capsule also measures pressure and temperature throughout its transit through the entire gastrointestinal tract, allowing calculations of total gastrointestinal transit time. This technology is evaluated as a method to diagnosis suspected gastrointestinal (GI) motility disorders such as gastroparesis, intestinal dysmotility, and constipation.

POLICY

IMPORTANT REMINDERS

ADDITIONAL INFORMATION  

The evidence to date is lacking on the clinical utility of testing. It is not possible to determine whether there is net improvement in health outcomes using wireless ingestible pH and pressure-sensing capsules versus standard diagnostic tests. Larger studies are needed that compare the results of the current conventional standard test for gastroparesis with those of the pH and pressure capsule.
