Video capsule endoscopy (VCE) is a noninvasive diagnostic tool used to observe the small intestinal mucosa. We report a case of a 57-year-old woman with T2DM, treated with continuous subcutaneous insulin infusion using second-generation OmniPod patch pump, undergoing VCE (Given M2A; VCE Ltd, Yoqneam, Israel) for melena and anemia. During VCE, an abnormal interruption of communication between video capsule and its receiver occurred. Two hours after capsule ingestion, the patient activated the insulin pump infusion through the Personal Diabetes Manager (PDM) because she drank a sugary beverage for the first time after ingestion. Due to this, we decided to repeat VCE after the removal of the insulin pump and PDM: at this time, the capsule recorded for more than 10 h without any interruption. The video capsule and second-generation OmniPod patch pump use the same radio frequency and this may cause interference between these two devices. In patients using second-generation OmniPod patch pump undergoing VCE, we suggest to switch to intravenous insulin infusion or multiple daily injection or to use a different model of VCE, as MiRoCam (Intromedic, Seoul, Korea).
