定义
十二指肠溃疡被定义为十二指肠粘膜由于腔内酸和胃蛋白酶的腐蚀性作用而出现的明显破损。组织学上,十二指肠溃疡明确为粘膜坏死,通过粘膜肌层延伸至粘膜下层。在内窥镜或放射学检查中,病变有明显的深度。当内壁上皮细胞破损局限于粘膜而未穿透粘膜肌层时,这种浅表病变称为 "糜烂"。
Duodenal ulcer is defined as a distinct breach in the mucosa of the duodenum as a result of caustic effects of acid and pepsin in the lumen. Histologically, duodenal ulcer is identified as necrosis of the mucosa extending through the muscularis mucosae into the submucosa. In the endoscopic or radiological view, there is an appreciable depth of the lesion. When the break of epithelial lining is confined to the mucosa without penetrating through the muscularis mucosae, the superficial lesion is called ‘erosion’.
