Small bowel strictures can be missed by current diagnostic methods.The Patency capsule is a new non-endoscopic dissolvable capsule which has as an objective of checking the patency of digestive tract,in a non-invasive manner.The available clinical trials have demonstrated that the Patency(C) capsule is a good tool for assessment of the functional patency of the small bowel,and it allows identification of those patients who can safely undergo a capsule endoscopy,despite clinical and radiographic evidence of small-bowel obstruction.Some cases of intestinal occlusion have been reported with the Patency(C) capsule,four of them needed surgery.So,a new capsule with two timer plugs (Agile(C) capsule) has been recently developed in order to minimize the risk of occlusion.This new device stars its dissolution process earlier (30 h after ingestion) and its two timer plugs have been designed to begin the disintegration even when the device is blocked in a tight stricture.
