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 © 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 © capsule, four of them needed surgery.So, a new capsule with two timer plugs (Agile © 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.
