水肿Edema · 食管 · 消化系统 · NTP ntp-0305
诊断要点:水肿应诊断并分级。作为炎症过程(如急性炎症)一部分的水肿,通常不单独记录,除非它是病变的重要组成成分。
病变描述
水肿液,尤其蛋白质含量高的液体,在细胞外间隙表现为均质的嗜酸性物质。它在处理过程中常丢失,在组织中可能表现为空白区域(Figure 1、Figure 2)。水肿是调节血浆、间质和细胞之间正常液体分布的任一因素发生改变的结果,例如血管通透性增加、血管内静水压升高、血管内渗透压降低和淋巴引流减少。食管水肿的一个常见原因是灌胃继发的创伤。

Comment:
Edema fluid, particularly fluid with a high protein content, appears as homogeneous eosinophilic material in extracellular spaces. It is often lost at processing and may appear as clear spaces in tissues ( Figure 1 and Figure 2 ). Edema is the result of alteration in any of the factors that regulate normal fluid distribution among the plasma, interstitium, and cells, such as increased vascular permeability, increased intravascular hydrostatic pressure, decreased intravascular osmotic pressure, and decreased lymphatic drainage. One common cause of edema in the esophagus is trauma secondary to gavage.
Recommendation:
Edema is diagnosed and graded. Edema as part of an inflammatory process, such as acute inflammation, is ordinarily not recorded separately unless it is a significant component of the lesion.
