BACKGROUND: @entity14 is the third most common @entity5 in Sweden, and incidence is increasing. We analysed @entity14 detection by colonoscopy in a defined population in Sweden. METHODS: All colonoscopy records for the period 1979-95 in one Swedish county (population 258,000) were retrieved. Information was obtained about @entity1 demographics, date of examination, endoscopists, indications, findings, colonoscopy type and completion level. Records were linked to the Swedish @entity5 Register and the Cause of Death Register. RESULTS: The majority of 2214 @entity14 were detected by means other than colonoscopy. In total, 192 were diagnosed and 6 were not detected by colonoscopy, with no significant differences in gender, age, indications, presence of @entity1127 or @entity7261 , time-period or experience of the endoscopist. The mean completion rate of the endoscopist was lower in @entity1 with undetected @entity5 . Coexisting @entity29 was more common in @entity1 with late diagnosis. Sensitivity was 97.0%, and higher when the indication was @entity548 , @entity5 or unclear X-ray findings. CONCLUSIONS: Sensitivity in detecting @entity14 was high, and the proportion detected by colonoscopy increased over time. Mean completion rate was lower in @entity1 with undetected @entity5 . Coexisting @entity8787 was more common in @entity1 with a late diagnosis.
