PillCam COLON 2(©) as a pan-enteroscopic test in Crohn's disease.

A recent paper by Boal Carvalho et al demonstrates the potential of PillCam COLON 2© (PCC2) as a pan-enteric investigation in Crohn’s disease (CD). Our own prospective data in patients with known CD also shows good correlation between PCC2 and small/large bowel investigations (R = 0.896, P < 0.0004/R = 0.6667, P < 0.035). Larger studies are warranted to prospectively validate the use of PCC2 in the investigation and monitoring of both small and large bowel CD.
