当院におけるカプセル内視鏡検査の画像不良事例と対策について

Recently, there have been some reports of electromagnetic interference during capsule endoscopy（CE）in regards to other medical devices and facility environment. These accidental events have not been analyzed sufficiently although academic societies and related ministries are proposing guidelines with cautious attention. Based on this, detailed analyses and development of solution are required. In this study, we review our experience with cases of accidental events during CE and assessed the causes and preventive solutions. A total of１４９CE cases（male :８９, female :６０, mean age :５６±１８．８）from January ２０１７ until December ２０１９ were analyzed retrospectively. Four cases（２%）with defective images were noted. Detailed events were as follows ;１ disorder of the sensor array, ２ recorder freezes, and １ electromagnetic interference. These mechanical and electromagnetic troubles should be assessed and shared among medical staffs and manufacturers to propose possible solutions and perform CE safely.
