We reviewed 195 colonoscopies to determine whether procedure efficiency differed with the use of an intermediate-length (135 cm) colonoscope compared with a long (165 cm) colonoscope. The cecum was intubated with the 135-cm scope in 92.6% of procedures and with the 165-cm colonoscope in 96.8% of procedures (chi 2 method, p = 0.26). The mean procedure duration was 36.7 min for 107 complete procedures performed with the 135-cm colonoscope and 48.4 min for 55 examinations using the 165-cm colonoscope (t test, p < 0.001). Colonoscopy with the 135-cm instrument required mean meperidine and midazolam doses of 59.9 mg and 1.8 mg, respectively, compared with doses of 69.1 mg and 2.0 mg, respectively, with the 165-cm colonoscope. The differences were not significant. Although the cecal intubation rate is slightly less for the 135-cm colonoscope, insertion takes significantly less time and is probably more comfortable for the patient than with the 165-cm colonoscope.
我们回顾了195例结肠镜检查病例，以确定使用中等长度（135厘米）结肠镜与长型（165厘米）结肠镜相比，操作效率是否存在差异。在92.6%的操作中，使用135厘米的结肠镜插入了盲肠，在96.8%的操作中，使用165厘米的结肠镜插入了盲肠（卡方检验，p = 0.26）。使用135厘米结肠镜完成的107例完整操作的平均操作时长为36.7分钟，而使用165厘米结肠镜进行的55例检查的平均操作时长为48.4分钟（t检验，p < 0.001）。使用135厘米器械进行结肠镜检查时，哌替啶和咪达唑仑的平均剂量分别为59.9毫克和1.8毫克，而使用165厘米结肠镜时，剂量分别为69.1毫克和2.0毫克。差异不显著。尽管135厘米结肠镜的盲肠插管率略低，但插入时间明显更短，对患者来说可能比使用165厘米结肠镜更舒适。
