概括
在食管胃二透镜前使用西梅西康前期药物显著改善了粘膜的可见性,并减少了手术时间. 40,80和160毫克的剂量提供了相似的益处,没有观察到与剂量相关的显著差异.
科学领域:
- 胃肠病学 胃肠病学
- 内镜检查是指内镜检查.
- 药理学 药理学是指药理学的学科.
背景情况:
- 使用西梅西康的前期治疗可以在食道胃管腺镜检查期间提高粘膜的可见性.
- 为此目的,最佳的西美西康剂量需要进一步研究.
研究的目的:
- 为了比较三种不同剂量的simethicone (40毫克,80毫克和160毫克) 的疗效,作为食道胃二透镜前期治疗.
- 评估西美西康对粘膜可见度,手术持续时间和患者满意度的影响.
主要方法:
- 一个随机,双盲,安慰剂控制的多中心试验,涉及268名患者.
- 患者在手术前15-30分钟接受了安慰剂或西梅西康 (40,80或160毫克) 稀释在正常盐水中.
- 使用经过验证的评分系统评估粘膜可见性;二次结果包括手术持续时间和患者满意度.
主要成果:
- 与安慰剂相比,所有simethicone组的总粘膜可见度得分明显较低 (P < 0.001).
- 与安慰剂相比,在所有simethicone手臂中,手术持续时间略有减少 (P < 0.001).
- 不同剂量的西米西康之间没有观察到粘膜可见性或程序持续时间的显著差异.
结论:
- 在40毫克,80毫克或160毫克的剂量中,西美西康的前期治疗有效地改善了食管胃管透镜期间的粘膜可见性.
- 这些剂量还会使手术时间略有缩短,但它们之间没有显著差异.
- 西米西康是改善内镜可视化的有价值的辅助剂.

Endoscopic Procedures I: Esophagogastroduodenoscopy
820
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Drugs for Peptic Ulcer Disease: Sucralfate as Mucosal Protective Agents
1.3K
In the intricate landscape of the gastric lumen, excessive acid secretion disrupts the natural defense mechanisms, weakening the mucus-bicarbonate barrier. This vulnerability allows pepsin to infiltrate epithelial cells, digesting mucosal proteins and triggering erosion, leading to ulcer formation.
In this scenario, mucosal protective agents like sucralfate play an essential role. Sucralfate, a complex of sulfated sucrose and aluminum hydroxide, demonstrates its usefulness in acidic conditions,...
