Capsule endoscopy in patients with cardiac pacemakers and implantable cardioverter defibrillators: (Re)Evaluation of the current state in Germany, Austria, and Switzerland 2010

Abstract

Background and Aims. The study was a repeated evaluation of the experience of capsule endoscopy (CE) in patients with cardiac pacemaker or implantable cardioverter defibrillator (ICD). Patients and Methods. A standardized questionnaire was sent by the manufactors Given Imaging and Olympus to all centers in Germany, Austria, and Switzerland providing capsule endoscopy service. The questionnaire covers the number of examined patients, monitoring during CE, check of the electric implants before and after CE, occurrence of arrhythmia, quality of CE video, complications, indication of CE, and type of institution. Results. Overall 580 questionnaires were sent to the users. 26/5 (Germany/Austria + Switzerland) of the questionnaires were sent back anonymously to the authors. 114 centers (82 hospitals, 11 surgeries, 21 without specification) replied. In 58 centers (51), patients with cardiac pacemaker (n = 300) and ICDs (n = 80) underwent uneventful capsule endoscopy. The predominant indication (patients with CP 97, patients with ICD 100) was mid gastrointestinal bleeding. Conclusion. The results of our inquiry show that in spite of formal contraindication CE is increasingly applied in bleeding patients with cardiac pacemakers/ICDs and seems to be safe even in a large cohort.
