肠镜检查时冲洗策略应用的临床研究
Clinical research on the application of flushing strategy during colonoscopy
摘要
Abstract
Objective To investigate the impact of different flushing strategies on procedure time and polyp detection rate(PDR)during colonoscopy.Methods A multicenter prospective controlled study was conducted,enrolling 248 patients who underwent colonoscopy at three hospitals from 2023 August to 2024 January.The patients were assigned to research group and control group randomly.The research group received a thorough flushing strategy during colonoscopy,while the control group received a limited flushing strategy.Clinical data,endoscopic procedure time,and polyp detection results were recorded and compared between the two groups.Results A total of 248 patients were enrolled,with 125 in the research group and 123 in the control group.Baseline characteristics were comparable between the two groups.The research group demonstrated a significantly higher PDR compared to the control group(P<0.01).Among patients with detected polyps,the research group detected more small polyps in the left colon than the control group(P<0.05).Conclusions The flushing strategy during colonoscopy improves PDR and increases the detection of small polyps in the left colon without prolonging the total procedure time.关键词
