The procedure involves ingestion of a capsule in the size of a large pill. The capsule contains a microscopic camera that will film the small intestine as well as part of the large intestine. The pictures are transmitted to a recording unit, which is placed around your waist. After about 8 hours, the recording is over. The capsule is disposable and will be expelled from your body naturally with the stool. Alternatively, there is a capsule that does not require the use of an external recording unit. You should collect it from your stool and bring it back after use for analysis.
In very rare cases and in certain diseases, the capsule is not excreted naturally. If this happens, the capsule may need to be removed endoscopically or with surgery.
It is essential for your doctor to know if you have a heart pacemaker or defibrillator, if you have problems with swallowing or if you are pregnant.
