概括
与传统结肠镜检查相比,Endocuff视觉辅助结肠镜检查 (EVC) 可以降低腺瘤错误率 (AMR),但不能显著提高腺瘤检测率 (ADR). 这凸显了结肠镜检查缺失腺瘤的持续挑战.
科学领域:
- 胃肠病学 胃肠病学
- 内镜检查是指内镜检查.
- 结肠直肠癌查 结肠直肠癌查
背景情况:
- 结肠直肠癌 (CRC) 查严重依赖结肠镜检测癌前病变.
- 提高腺瘤检测率 (ADR) 和降低腺瘤错误率 (AMR) 对于有效的CRC预防至关重要.
- 内镜视觉 (EVC) 是一种设备,旨在增强结肠镜检查期间的粘膜可视化.
研究的目的:
- 为了比较Endocuff视觉辅助结肠镜 (EVC) 和常规结肠镜 (CC) 之间的ADR和AMR.
- 评估EVC在改善结肠镜检查期间腺瘤检测的疗效.
- 评估EVC对减少遗漏腺瘤的影响.
主要方法:
- 一个多中心,国际,背靠背,随机结肠镜试验.
- 包括40至75岁的接受查,监测或诊断结肠镜检查的患者.
- 随机分为四个组:2x CC,CC然后是EVC,EVC然后是CC,以及2x EVC.
主要成果:
- 与CC相比,EVC没有显著改善ADR (41.1%与35.5%,P=.125).
- EVC显著降低了AMR的11.7% (29.6%对17.9%,P=.049). 这是一个显著的降低.
- 在第一次手术中错过的腺瘤很少具有先进的病理特征 (3.7%).
结论:
- 视觉辅助结肠镜可减少缺失腺瘤的风险,但不能显著改善ADR.
- 很大一部分腺瘤 (约25%) 仍然无法通过常规结肠镜检查发现.
- 影响遗漏腺瘤的因素包括患者年龄,肠道准备质量和手术区域.

Endoscopic Procedures II: Colonoscopy
107
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
87
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
