安装透明帽并二氧化碳气体注入对结肠镜检查进镜速度及结肠息肉检出率的影响

摘要： 目的 观察并探讨肠镜前端安装透明帽联合二氧化碳CO2 气体注入对结肠镜检查进镜速度及镜 下息肉检出率的影响。方法 将2014 年1 月-2016 年6 月拟行结肠镜检查的216 例患者据随机数字表分为 A、B、C 3 组，每组72 例，A 组患者肠镜前端安装透明帽而后行结肠镜检查，B 组检查前肠镜不安装透明帽， 进镜前肠管内注入CO2 气体，C 组联合采用上述两种方法而后再行肠镜检查，比较3 组患者检查过程中进镜 速度及息肉检出率差异。结果 A、B、C 3 组受检者肠镜达到回盲部比例差异无统计学意义（95.8% vs 90.3% vs 98.6%）（χ2=5.34，P =0.069）；到达回盲部平均时间C 组A 组>B 组（38.9% vs 34.7% vs 23.6%）（χ2= 4.10，P =0.129），A、B、C 3 组微小结肠息肉检出率（30.6% vs 18.1% vs 36.1%）及右半结肠息肉检出率（20.8% vs 8.3% vs 23.6%）差异均有统计学意义（χ2=6.08，P =0.048；χ2=6.58，P =0.037）。患者撤镜后10 min[（4.35± 0.62）vs（4.88±0.85）vs（5.57±1.05）] 和30 min[（3.04±0.37）vs（3.30±0.56）vs（4.41±0.84）]VAS 评分C 组
Abstract: Objective To observe and explore the effects of transparent cap-fitted colonoscope combined with carbon dioxide injection on the cecal intubation time and detection of colonic polyps during enteroscopy. Methods 216 patients underwent colonoscopy from January 2014 to June 2016 were selected and randomly divided into A, B, C groups according to random number table, 72 cases in each. Group A with transparent cap-fitted colonoscopy, group B with CO2 injection before colonoscopy, and group C combined with the above two methods and then underwent colonoscopy, cecal intubation time and colonic polyp detection rate were compared among the three groups during the inspection. Results A, B, C groups with cecal intubation ratio showed no significant differences (95.8% vs 90.3% vs 98.6%) (χ2 = 5.34, P = 0.069); the sequence of mean cecal intubation time was group C group A>group B (38.9% vs 34.7% vs 23.6%) (χ2 = 4.10, P = 0.129). The sequences of visual analogue scale score after 10 min [(4.35 ± 0.62) vs (4.88 ± 0.85) vs (5.57 ± 1.05)] and 30 min [(3.04 ± 0.37) vs (3.30 ± 0.56) vs (4.41 ± 0.84)] of coloscope withdraw were both group C
