概括
内镜超声波 (EUS) 有效地表征下胃肠子皮层病变 (LGI SELs). 与标准活检相比,块状组织采集方法提供了更高的诊断产量,提高了潜在恶性SELs的检测.
科学领域:
- 胃肠病学 胃肠病学
- 医疗成像医学成像
- 内镜检查是指内镜检查.
背景情况:
- 越来越多地检测到下胃肠道亚皮质病变 (LGI SELs).
- 对于LGI SEL,内镜超声波 (EUS) 的诊断准确性需要进一步定义.
研究的目的:
- 为了描述LGI SELs的EUS特征.
- 评估LGI SELs的最佳组织采集技术.
主要方法:
- 对218名患有244例LGI SEL的患者进行了回顾性观察性研究.
- 分析EUS特征,包括位置,尺寸,壁层,回声性和边界特征.
- 对各种组织采集方法的诊断产量的评估.
主要成果:

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

1.3K
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...

The GI tract, from beginning to end, is made up of four continuous tissue layers that adjust their structure according to their specific roles. These layers, from innermost to outermost, are known as the mucosa, submucosa, muscularis, and serosa, which are continuous with the mesentery.
The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...

When a force is applied parallel to the top surface of a solid, it resists the applied force due to the internal frictional forces between the layers of the solid known as shearing resistance. However, when the force is removed, the shearing forces restore the original shape of the solid. Other deformation forces also cause temporary changes in shape if the forces are not beyond a threshold magnitude. Solids tend to retain their shape, making the study of their rest and motion easier. Beyond...
