Design outcomes

Primary

MeasureTime frame
The colorectal adenoma detection rate (ADR) in patients with duodenal epithelial neoplasia and with medical checkup

Secondary

MeasureTime frame
1) The ADR for each mucous phenotype (gastric type/intestinal type) in patients with DET 2) The polype detection rat (PDR) in patients with DET and with medical checkup, the PDR for each mucous phenotype (gastric type/intestinal type) in patients with DET 3) The percentage of advanced neoplasia (ex, adenoma over 10mm, adenoma with severe atypia, villous adenoma or adenocarcinoma) in patients with DET and with medical checkup, that percentage for each mucous phenotype (gastric type/intestinal type) in patients with DET 4) The percentage of colorectal cancer including advanced cancer in patients with DET and with medical checkup, that percentage for each mucous phenotype (gastric type/intestinal type) in patients with DET 5) The percentage of laterally spreading tumor (LST) in patients with DET and with medical checkup, that percentage for each mucous phenotype (gastric type/intestinal type) in patients with DET 6) The percentage of sessile serrated adenoma/polyp (SSA/P) in patients with DET and with medical checkup, that percentage for each mucous phenotype (gastric type/intestinal type) in patients with DET 7) The percentage of sessile serrated adenoma/polyp (SSA/P) in patients with DET and with medical checkup, that percentage for each mucous phenotype (gastric type/intestinal type) in patients with DET 8) The mean number of colorectal adenoma in patient with DET and with medical checkup, the mean number of that for each mucous phenotype (gastric type/intestinal type) in patients with DET 9) The mean number of colorectal polyp in each patient with DET and with medical checkup, the mean number of that for each mucous phenotype (gastric type/intestinal type) in patients with DET 10) The mean number of SSA/P in each patient with DET and with medical checkup, the mean number of that for each mucous phenotype (gastric type/intestinal type) in patients with DET
