Clinical Study

Clinical Experience with the PillCam Patency Capsule prior to Video Capsule Endoscopy: A Real-World Experience

Table 2

PC and VCE findings: transit time of the PC shown by observed natural excretion, negative RFID-scan, or projection of the PC to the colon via radiological examination. Furthermore the findings of the VCE are shown. No complications appeared during the VCE.
