Abstract：Objective:To analyze the application effect of water-injected colonoscopy combined with short trans-parent front cap in the examination of colon polyps.Methods:A total of 164 patients with relevant indications who un-derwent colon polyp examination in hospital from December 2022 to December 2023 were randomized,and 82 patients in each group.The control group underwent routine colonoscopy,and the observation group underwent water-injected colonoscopy combined with a short transparent cap in front of the group,and the time required for examination,polyp detection rate,degree of abdominal distension and abdominal pain,incidence of complications and patient satisfaction were compared between the two groups.Results:The time to blinding,the time of withdrawal and the total time of ex-amination in the observation group were significantly shorter than those in the control group,the polyp detection rate in the observation group was significantly higher than that in the control group,the visual analogue scale(VAS)score of abdominal distension and abdominal pain VAS score in the observation group was significantly lower than that in the control group,and the satisfaction rate of patients in the observation group was significantly higher than that in the con-trol group,and the differences in the above indexes were statistically significant(P＜0.05).The complication rate of the experimental group was similar to that of the control group,and the difference was not statistically significant(P＞0.05).Conclusion:Water injection colonoscopy combined with a short transparent front cap can improve the detection rate of colon polyps,shorten the examination time,reduce patient discomfort,improve patient satisfaction,and has good safety.
