Reports of virtual colonoscopy demonstrate sensitivity similar to that of conventional colonoscopy for polyps 5 mm or larger, suggesting the validity of its use for colorectal cancer screening. Critical to the success of either procedure is the ability to evaluate the entire colon. Cecal intubation rates during diagnostic or screening colonoscopies vary from 53 to 99 percent. We describe the added value of using a gastroscope to perform a colonoscopic examination that would otherwise result in an incomplete colonoscopy.
From January 1, 2002 to December 31, 2002 a total of 1,979 colonoscopies were performed. A gastroscope was used in 1.3 percent (n = 26) of these colonoscopies in an effort to complete the index examination initially started with a standard or pediatric colonoscope. The success rate was defined as intubating proximal to the initial area of impasse and entering the cecum.
Cecal intubation was achieved in 62 percent of patients.
In patients with incomplete conventional colonoscopy, the gastroscope can usually advance through the initial area of impasse with a cecal intubation rate of 62 percent.
虚拟结肠镜检查的报告显示，对于5毫米或更大的息肉，其敏感性与传统结肠镜检查相似，这表明其用于结直肠癌筛查的有效性。两种检查方法成功的关键在于能够评估整个结肠。诊断性或筛查性结肠镜检查期间的盲肠插管率在53%至99%之间。我们描述了使用胃镜进行结肠镜检查的附加价值，否则会导致结肠镜检查不完整。
2002年1月1日至2002年12月31日，共进行了1979例结肠镜检查。其中1.3%（n = 26）的结肠镜检查使用了胃镜，以完成最初用标准或小儿结肠镜开始的索引检查。成功率定义为在最初的梗阻区域近端插管并进入盲肠。
62%的患者实现了盲肠插管。
在传统结肠镜检查不完整的患者中，胃镜通常可以通过最初的梗阻区域推进，盲肠插管率为62%。
