Magnetic-assisted Capsule Endoscope With 3D Images in EV Detection in Cirrhotic Patient

Plain-language summary

Newly development of capsule endoscopy provides a comfortable and minimal invasive modality which is an alternative to conventional esophagogastroduodenoscopy(EGD). The use of capsule endoscopy beyond the small bowel is increasing and several capsule endoscopy systems have been introduced for the examination of the esophagus and colon. The current capsule endoscopy systems are less effective for the upper gastrointestinal tract examination. Short transit time in the esophagus and the passive movement of the capsule makes it more difficult to identify or visualize the lesion comparing with traditional EGD. The sensitivity rate of esophageal varices detection from capsule endoscopy was ranging from 65% to 80%. In order to control the capsule in the gastrointestinal tract for better visualization, many methods are invented. Magnetically assisted capsule endoscopy systems and string-mounted capsule endoscopy are applied in many studies. Magnetically assisted capsule endoscopy system and string-mounted capsule endoscopy are used to control the capsule endoscopy for elongating esophagus transit time to have a better visualization of the esophagus. The InsightEyes EGD System combines the string and magnetic assisted capsule endoscopy system to provide a real-time high-quality image during the examination. On the other hand, 3D image processing can be used for distinguishing the esophageal varices and normal folds well, theoretically. Thus, in this study, the investigators combine string, magnetically assisted capsule endoscopy systems, and 3D image processing together to form a new system for improving the detection of esophageal varices and other gastric lesions.
