There is general consensus that water instillation helps insert a colonoscope. However, the most effective method for water instillation has not yet been established, especially for endoscopists-in-training. The aim of this study was to determine volume and temperature for effective water instillation colonoscopy.
This is a prospective, randomized, controlled trial that was carried out at a single center, and a total of 207 consecutive subjects who underwent colonoscopic examination for health checkup were included in the study. Water instillation of supplied water was conducted under four different conditions: 100 and 300 ml at room temperature, 300 ml at 30 °C and no use of water instillation. The following parameters were recorded and analyzed: intubation success rate, independent predictors of successful intubation and intubation time to reach the cecum.
The intubation success rate was not significantly different between individual groups. Independent predictors of successful intubation were younger age (P = 0.004) and later examined subjects (P = 0.016). The 300-ml warm water instillation during colonoscopy significantly reduced intubation time over the conventional method without water instillation (P = 0.034).
Instillation of 300-ml warm (30 °C) water during colonoscopy can reduce cecal intubation time for in-training endoscopists without improving the intubation success rate.
人们普遍认为注水有助于插入结肠镜。然而，尚未确定最有效的注水方法，尤其是对于内镜培训师。本研究的目的是确定有效注水结肠镜检查的水量和温度。
这是一项在单中心进行的前瞻性、随机、对照试验，共纳入 207 例因健康检查而行结肠镜检查的连续患者。在四种不同条件下进行供应水的注水：室温下的 100 和 300ml、30°C 下的 300ml 和不使用注水。记录和分析以下参数：插管成功率、插管成功的独立预测因素和到达盲肠的插管时间。
各组的插管成功率无显著差异。插管成功的独立预测因素是年龄较小（P=0.004）和较晚接受检查的患者（P=0.016）。结肠镜检查时 300ml 温水冲洗可显著缩短插管时间，优于不使用注水的常规方法（P=0.034）。
在结肠镜检查中注入 300ml 温水（30°C）可以减少受训内镜医师的盲肠插管时间，而不提高插管成功率。
