As with all ingestible capsule devices there some risks (although rare) involved with the procedure:
Capsule aspiration (going into the wind-pipe) during swallowing – there have been very few cases of this happening, however, patients with proven or suspected swallowing disorders should not be referred for the test. If you have trouble swallowing tablets, please inform your consultant.
Capsule retention (not passing naturally or getting ‘stuck’ in the bowel) – there is a less than 1% report of the SmartPill being retained for longer than 7 days after being swallowed. These have all been either passed naturally or required a further non-surgical procedure to retrieve the capsule.
In the extreme event this is retained within the small bowel a surgical option may be considered and an operation to remove it may be required. In the event of a complication or emergency, patient care will be consultant led and you should call your consultant on the emergency number provided.
