摘要
目的:比较水浸法结肠镜检查(WAC)与常规二氧化碳充气结肠镜检查(CC)在新手内镜检查中的应用,重点分析手术时间、安全性和学习曲线。方法:我们在泰国清迈大学医院进行了一项前瞻性、随机(1:1)、单中心试验。结果:在250名随机患者中,230名完成了方案(WAC, n=113;CC, n = 117)。两组间平均CIT具有可比性(10.6±4.2 min vs 9.8±3.9 min;p = 0.35)。6.2%的WAC和5.1%的CC手术发生了技术失败,在手术难度评分、镇痛要求或患者不适评分方面没有显著差异。两组间不良反应相似(40.7% vs 33.3%;p = 0.25)。学习曲线显示,两组受试者的CIT水平呈平行、渐进式下降。结论:WAC是一种安全有效的替代CC的新手内镜医师,具有相似的手术时间,学习曲线和安全性。这些发现支持将WAC纳入胃肠病学培训计划。试验注册号:TCTR20230324001。
Assessing water-assisted colonoscopy in beginner endoscopists: a randomised controlled trial.
Objective: To compare water-assisted colonoscopy (WAC) using the water immersion technique with conventional carbon dioxide insufflation colonoscopy (CC) in novice endoscopists, focusing on procedure time, safety and learning curves.
Methods: We conducted a prospective, randomised (1:1), single-centre trial at Chiang Mai University Hospital, Thailand. Six gastroenterology fellows with <150 prior colonoscopies received standardised training before performing elective screening colonoscopies using either WAC or CC techniques. Patients were randomly assigned to WAC or CC groups. The primary outcome was caecal intubation time (CIT). Secondary outcomes included technical failure, procedural difficulty, patient discomfort, complications, withdrawal time and adenoma detection rate (ADR).
Results: Of 250 randomised patients, 230 completed the protocol (WAC, n=113; CC, n=117). Mean CIT was comparable between groups (10.6±4.2 min vs 9.8±3.9 min; p=0.35). Technical failure occurred in 6.2% of WAC and 5.1% of CC procedures, with no significant differences in procedural difficulty ratings, analgesic requirements or patient discomfort scores. ADR was similar between arms (40.7% vs 33.3%; p=0.25). Learning curves demonstrated parallel, progressive reductions in CIT among fellows in both groups.
Conclusion: WAC is a safe and effective alternative to CC for novice endoscopists, with similar procedure times, learning curves and safety profiles. These findings support the inclusion of WAC in gastroenterology training programmes.
