Variable stiffness colonoscope may be useful in performing colonoscopies in nonsedated patients or under endoscopist-controlled sedation. The objective of this study is to evaluate whether this instrument facilitates colonoscopy in patients under deep sedation monitored by an anaesthesiologist.
Prospective and randomized study enroling consecutive patients referred for colonoscopy under deep sedation monitored by an anaesthesiologist. In group I, a variable stiffness colonoscope was used, whereas in group II, a standard colonoscope was used. The main variable was the need to change the position of the patient during the endoscopy.
Fifty-six patients were included in group I (variable stiffness colonoscope) and 54 in group II (standard colonoscope). The caecum was reached in 92.9% of patients in group I and in 90.7% of group II (P=0.7). The time required to reach the caecum was significantly less in group I (6.14±3.5 vs. 7.7±3.8; P=0.035). The variable stiffness colonoscope was effective in 66.7% of cases. Changing the position of the patient was necessary in 12.5% of cases in group I compared with 33.3% of cases in group II (P=0.01).
The variable stiffness colonoscope avoids the need to change the patient's position and reduces caecal intubation time in patients undergoing colonoscopy under deep sedation controlled by an anaesthesiologist.
可变硬度结肠镜可能有助于在非镇静患者或在内镜医师控制下镇静的情况下进行结肠镜检查。本研究的目的是评估该仪器是否有助于在麻醉医师监测下深度镇静下进行结肠镜检查的患者。
前瞻性、随机研究纳入连续患者，在麻醉医师监测下深度镇静下接受结肠镜检查。在 I 组中，使用可变硬度结肠镜，而在 II 组中，使用标准结肠镜。主要变量是在内镜检查过程中是否需要改变患者的位置。
56 例患者被纳入 I 组（可变硬度结肠镜），54 例患者被纳入 II 组（标准结肠镜）。I 组患者盲肠到达率为 92.9%，II 组为 90.7%（P=0.7）。到达盲肠所需的时间在 I 组明显更短（6.14±3.5 与 7.7±3.8；P=0.035）。可变硬度结肠镜在 66.7%的病例中有效。I 组中需要改变患者体位的病例为 12.5%，而 II 组为 33.3%（P=0.01）。
在麻醉医师控制下深度镇静下进行结肠镜检查的患者中，可变硬度结肠镜可避免改变患者体位，并减少盲肠插管时间。
