Core Tip
Core tip: The aims of this study were to characterize small bowel (SB) tumors detected by capsule endoscopy (CE) and identify SB tumors missed by CE. The study included 150 consecutive CE investigations. Following CE, the medical records of the study population were reviewed and the patients contacted by telephone or postal mail. National cancer registries were searched to identify missed neoplasms. CE detected 15 SB tumors (10%). During the follow-up period, three additional SB tumors were found. The sensitivity of CE for tumor detection was 83.3% and the negative predictive value 97.6%. The specificity and positive predictive value were both 100%.
