EPK-i对慢性胃炎镜下黏膜形态诊断价值的研究

目的：探讨Pentax内镜EPK-i系列对慢性萎缩性胃炎（CAG）黏膜形态的诊断价值。方法：对200例内镜诊断为CAG的黏膜形态进行研究,比较普通白光模式与特殊模式对典型表现的发现率。结果：100例描述为黏膜变薄者,血管（V）模式发现89例,普通白光模式发现69例,两者比较差异有统计学意义（字2=12.055,P=0.001）;100例描述为黏膜粗糙者,胃（G）模式发现91例,腺管开口（P）模式发现84例,普通白光模式发现71例,前两者比较差异无统计学意义（P〉0.05）,前两者分别与普通模式比较差异均有统计学意义（P〈0.05）。结论：镜下普通白光模式肉眼诊断与病理诊断符合率不高,特殊模式对典型黏膜形态的发现具有指导意义,通过多模式结合提高CAG诊断率。

Diagnostic Value of EPK-i Endoscopy in Chronic Atrophic Gastritis

Objective： To investigate Pentax Endoscopy EPK-i scan series for the diagnosis value of mucosal morphology in chronic atrophic gastritis（CAG）. Methods： Study the mucosal morphology of 200 patients with CAG by different models of EPK-i endoscopy, and compare the ordinary white pattern and special mode of the typical manifestations of discovery rate. Results： In 100 cases described as mucosal thinning, vascular（V） pattern found 89 cases, compared with the common light pattern 69 cases, the difference was statistically significant（X2=12.055, P=0.001）. In 100 cases described as mucosal roughness, gastric（G） pattern was found in 91 cases, crypt（P） pattern was found in 84 cases, and the common light pattern was found in 71 cases. The difference was not statistically significant in the first two comparison（P0.05）, but the difference was statistically significant in common mode compared with G pattern or P pattern（P0.05）. Conclusion： The compliance rate of endoscopic diagnosis and pathological diagnosis is not high in nomal white model. The special modes have guilding significance in finding typical mucosal morphology. We can improve the diagnosis of CAG by multi-mode joint.
