概括

胃部的黑斑与老年和某些药物有关,并表明Helicobacter pylori感染的活性较低. 在这些地方发现了铁沉积物,为它们的原因提供了新的见解.

科学领域:

胃肠病学胃肠病学
病理学病理学病理学
内镜检查是指内镜检查.

背景情况:

在上部胃肠内镜检查期间观察到黑斑 (BSs),特别是在为Helicobacter pylori治疗的患者中.
患者人口统计和BSs的精确组成尚未得到充分了解.

研究的目的:

澄清BSs. 的临床病理特征和患者人口统计数据.
用先进的显微镜技术分析BSs的元素组成.

主要方法:

对6778例上部胃肠内镜病例 (2017-2022) 的回顾性分析.
单变量和多变量分析以确定BSs的风险因素.
纳米套装相关光电子显微镜 (CLEM) 与能量分散式X射线光谱学用于BSs的元素分析.

主要成果:

老年,质子抑制剂,他类药物,皮质类固醇和抗血栓药物被确定为BSs的危险因素.
BSs与胃缩的增加和活性H. pylori感染的减少相关.
用NanoSuit-CLEM在BS地点特别确定了铁沉积.

结论:

内镜上的黑点可能意味着没有活跃的H. pylori炎症.
在BS中识别铁沉积提供了对其病因和形成机制的新见解.

Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies

Peptic ulcer disease (PUD) presents with diverse symptoms depending on the location and severity of the ulcer. Clinical manifestations of peptic ulcer include dull pain and a burning sensation in the mid-epigastric region.
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
