Endoluminal capsule monitoring is categorized as a non-invasive medical procedure used in diagnosing and monitoring the progression of abnormalities in the gastrointestinal system.


Once the need is identified to monitor the gastrointestinal system and the patient has a working system, they will ingest a water-tight capsule that contains a miniaturized wireless radio transmitter. Once it is ingested, it sends signals to a radio receiver. The data is then processed and presented on a computer for the technician to record.

Types of Transmitters

There are several types of sensors used within the capsule and are used according to the data that is required for the individual patient. They include:

  • Intraluminal- pH in the esophagus, stomach and duodenum (the first section in the small intestine)
  • Intestinal- motility (peristalsis)
  • Intraluminal – pressure within the system

Some capsules have the ability to transmit video and are referred to as video pills.

These capsules are not disposable and are recovered from the feces of the patient to be sterilized and used again.
