Efficacy and Safety of Bowel Preparation for Patency Capsule in CD Patients Who Previously Failed Patency Capsule

The goal of this observational study is to evaluate the success rate of a second bowel preparation protocol for patency capsule (PC) in Crohn Disease (CD) patients who failed to pass an initial protocol PC on a previous attempt. The main question it aims to answer is what is the percentage of patients successfully passing the second PC test, among those who failed the first attempt. Participants who will fail the PC test will be scheduled for another test with a different preparation protocol. Participants will be asked to report capsule expulsion and send a photo for documentation or report the result of the abdominal X-ray preformed 28-30 hours post swallowing. .
