This study adopts a prospective and self-controlled design. The subjects are adult patients (≥18 years old) who have symptoms of small bowel disease or suspected GI bleeding; Subjects swallow two types of SB capsules approximately 40 minutes apart in a randomized order. During the capsule endoscopy, the doctor can view the small bowel images taken by the capsules in real time. This study adopts a method of independent image reading in the participating centers. Two physicians of digestive endoscopy respectively review the images captured by the experimental capsule and the control capsule for normal versus abnormal findings, type of findings and categorization (lesions, polyps, bleeding, etc.), capsule transit time, reading time, and image quality.
This study uses a comparative method to evaluate the performance of the NaviCam SB capsule endoscope system in comparison to the PillCam SB3 capsule system for the diagnosis of small bowel diseases.
