AIm.To assess the prevalence and location of ad-vanced neoplasia in patients undergoing colonoscopy,and to com.are the yield per ***:In a m.lticenter colonoscopy survey (n = 18 hospitals) in the Am.terdam.area (Northern Holland),data of all colonoscopies perform.d during a three m.nth period in 2005 were analyzed. The location and the histological features of all colonic neoplasia were recorded. The prevalence and the distribution ofadvanced colorectal neoplasia and differences in yield between indication clusters were evaluated. Advanced neoplasm.was defi ned as adenom. > 10 m. in size,with > 25% villous features or with high-grade dyspla-sia or ***:A total of 4623 eligible patients underwent a total colonoscopy. The prevalence of advanced neo-plasia was 13%,with 281 (6%) adenocarcinom.s and 342 (7%) advanced adenom.s. Sixty-seven percent and 33% of advanced neoplasia were located in the distal and proxim.l colon,respectively. Of all patients with right-sided advanced neoplasia (n = 228),51% had a norm.l distal colon,whereas 27% had a syn-chronous distal adenom.. Ten percent of all colono-scopies were perform.d in asym.tom.tic patients,7% of whom.had advanced neoplasia. In the respective procedure indication clusters,the prevalence of right-sided advanced neoplasia ranged from.11%-57%. CONCLUSION:One out of every 7-8 colonoscopies yielded an advanced colorectal neoplasm. Colonoscopy is warranted for the evaluation of both sym.tom.tic and asym.tom.tic patients.
