Core Tip
Core Tip: Colon capsule endoscopy is becoming popular as a screening test for colorectal cancer in patients where colonoscopy is difficult. Its accuracy is comparable to that of colonoscopy; however, the outcomes are unknown. This study evaluated the follow-up methods, presence or absence of polyps and colorectal cancer, and cancer deaths after follow-up in Japanese patients with negative capsule endoscopy findings.
