重视这些胃肿瘤的误判和识别

Pay attention to the misdiagnosis and identification of these gastric neoplasms

内镜下易被漏诊和误诊的胃肿瘤包括胃炎型胃癌、浅表扩散型胃癌、胃MALT淋巴瘤和局限性皮革胃等类型。胃癌内镜下黏膜色泽、微血管和皱襞改变对胃癌分化程度和浸润深度的判断具有重要作用。在此对这些胃肿瘤的内镜特征以及胃癌内镜下分化程度的判断进行概述。重视上述胃肿瘤的误判和内镜下胃癌黏膜色泽和皱襞的改变,有助于提高胃肿瘤的早期诊断水平。

Some gastric neoplasms, including gastritis-like gastric cancer, superficial spreading type gastric cancer, primary gastric mucosa associated lymphoid tissue lymphoma （MALT） and limited linitis plastica , are prone to be missed diagnosed and misdiagnosed in gastroscopy. The changes of mucosa color, capillaries and mucosal folds in gastric cancer are important to judge the differentiation degree and the depth of invasion. This article summarizes the endoscopic features of these gastric neoplasms and the differentiation degree of gastric cancers. It is helpful to enhance the early diagnostic level of gastric neoplasms that we pay more attention to the misdiagnosis of these gastric neoplasms and the changes of mucosa color and mucosal folds in gastric cancers.
