Use of a patency capsule in the daily practice

We read with great interest the paper by Albuquerque et al. entitled "Predictive factors of small bowel patency in Crohn's disease patients". Despite being a safe procedure, capsule endoscopy (CE) retention is a complication that should be kept in mind, especially in Crohn's disease (CD) patients. However, the risk of CE retention can be minimized using the patency capsule (PC). Although some clinical trials confirm its effectiveness, its use in daily practice has been poorly investigated. Albuquerque et al. report a PC negative predictive value (NPV) of 100% in this setting.
