PTH-050 Robot magnet-controlled upper gi capsule endoscopy using the ankon navicam® system: first reported experience outside china

IntroductionGastroscopy (OGD) is invasive and not always well tolerated. Capsule endoscopy of the upper GI tract might be possible if effective control allowed movement to all areas of the stomach which, unlike the small bowel, is capacious and irregular in shape. The NaviCam® (Ankon Technologies Co, Ltd Wuhan, Shanghai, China) contains magnetic material and can be controlled by an external robot magnet, the polarity and proximity of which can be manipulated using joysticks. Two frames per second allow real-time visualisation. A Chinese multicentre study has shown a high sensitivity and specificity for detecting focal gastric lesions when compared to OGD (1). In this study, imaging quality and patient tolerance of upper GI examination using the robot magnet-controlled NaviCam® was assessed.MethodPatients with symptoms of dyspepsia swallowed 100mls of water containing 10mls simethicone 15 min prior to 1L of water followed by the NaviCam®. Both clarity of gastric views and adequacy of gastric distension were assessed (1, poor; 2, reasonable; 3, good), as was completeness of views of all areas of the gastric mucosa (1,>75% obscured; 2,>50% obscured; 3,
