摘　　要：目的:探讨C T扫描联合结肠镜检查诊断急性下消化道出血的效果.方法:选取2016年3月-2017年12月我院收治的急性下消化道出血患者150例为研究组,另选取同期分别行常规结肠镜检查及紧急结肠镜检查的急性下消化道出血患者为常规组和紧急组,各30例.观察分析三组检查成功率、总体诊断率、出血原因、检查耗时、出血量、输血量、止血率及住院时间.结果:研究组检查成功率为97.33%,紧急组检查成功率为93.33%,常规组检查成功率为76.67%,研究组和紧急组与常规组比较,差异有统计学意义(P﹤0.05);三组首次检查发现出血病灶的总体诊断率分别为96.67%、90.00%和73.33%,研究组和紧急组与常规组比较,差异有统计学意义(P﹤0.05);研究组检查耗时及住院时间明显短于紧急组和常规组,且紧急组检查耗时及住院时间亦短于常规组,差异均有统计学意义(P﹤0.05);研究组出血量、输血量明显少于紧急组和常规组,且紧急组出血量、输血量亦少于常规组,差异均有统计学意义(P﹤0.05);研究组止血率明显高于紧急组和常规组,且紧急组止血率亦高于常规组,差异均有统计学意义(P﹤0.05).结论:C T扫描联合结肠镜检查诊断消化道出血患者,有助于提高检查成功率及总体诊断率,缩短检查耗时,及时给予针对性治疗,减少出血量,利于患者康复.Objective To explore the prospective study of emergency CT scan in determining the optimal time for colonoscopy in patients with acute lower gastrointestinal bleeding.Methods:150 patients with acute lower gastrointestinal hemorrhage admitted to our hospital from March 2016 to December 2017 were selected as the study group.Another 30 patients with acute lower gastrointestinal hemorrhage who underwent routine colonoscopy and emergency colonoscopy at the same time were selected as the routine group and the emergency group respectively.The success rate,overall diagnostic rate,cause of bleeding,time consuming,amount of bleeding,amount of blood transfusion,hemostasis rate and length of hospital stay were observed and analyzed.Results:The success rate of the study group was 97.33%,that of the emergency group was 93.33%,and that of the routine group was 76.67%.The difference was statistically significant(P<0.05).The overall diagnostic rates of the first examination of the three groups were 96.67%,90.00%and 73.33%,respectively.The difference was statistically significant(P<0.05).The examination time and hospitalization time of the study group were significantly shorter than those of the emergency group and the regular group.The blood loss and transfusion volume in the study group were significantly less than those in the emergency group and the routine group,and the blood loss and transfusion volume in the emergency group were also less than those in the routine group,the difference was statistically significant(P<0.05);the hemostasis rate in the study group was significantly higher than that in the emergency group and the routine group,and the hemostasis rate in the emergency group was significantly higher than that in the routine group(P<0.05).The difference was statistically significant(P<0.05).Conclusion:Emergency CT scan is helpful to improve the success rate and overall diagnostic rate of colonoscopy in patients with acute lower gastrointestinal hemorrhage,shorten the examination time,give timely targeted treatment,
