| 1 | Kyoto classification of gastritis:Advances and future perspectives in endoscopic diagnosis of gastritis显示文摘This editorial provides an update of the recent evidence on the endoscopy-based Kyoto classification of gastritis,clarifying the shortcomings of the Kyoto classification,and providing prospects for future research,with particular focus on the histological subtypes of gastric cancer(GC)and Helicobacter pylori(H.pylori)infection status.The total Kyoto score is designed to express GC risk on a score ranging from 0 to 8,based on the following five endoscopic findings:Atrophy,intestinal metaplasia(IM),enlarged folds(EF),nodularity,and diffuse redness(DR).The total Kyoto score reflects H.pylori status as follows:0,≥2,and≥4 indicate a normal stomach,H.pylori-infected gastritis,and gastritis at risk for GC,respectively.Regular arrangement of collecting venules(RAC)predicts noninfection;EF,nodularity,and DR predict current infection;map-like redness(MLR)predicts past infection;and atrophy and IM predict current or past infection.Atrophy,IM,and EF all increase the incidence of H.pylori-infected GC.MLR is a specific risk factor for H.pylori-eradicated GC,while RAC results in less GC.Diffuse-type GC can be induced by active inflammation,which presents as EF,nodularity,and atrophy on endoscopy,as well as neutrophil and mononuclear cell infiltration on histology.In contrast,intestinal-type GC develops via atrophy and IM,and is consistent between endoscopy and histology.However,this GC risk-scoring design needs to be improved. | Osamu Toyoshima Toshihiro Nishizawa | 2022 | World Journal of Gastroenterology2022，28，43： | 0 |
| 2 | 胃黏膜下肿物的EUS诊断分析及准确率的影响因素分析显示文摘目的探讨胃黏膜下肿物的超声内镜(EUS)诊断分析及准确率的影响因素。方法选取2016年1月至2022年10月在我院治疗的胃黏膜下肿物患者130例,均给予EUS检查,分析EUS诊断胃黏膜下肿物的准确率,以及分析EUS诊断准确率的影响因素。结果经病理学检查,130例患者中,胃肠间质瘤患者98例,平滑肌瘤14例,异位胰腺4例,脂肪瘤10例,神经内分泌瘤4例。对患者不同病理结果(胃肠间质瘤、平滑肌瘤和其他)间一般资料进行统计学处理,各类别在性别、年龄、BMI和肿物直径等方面均处于同等水平,差异无统计学意义(P>0.05)。EUS诊断胃黏膜下肿物的准确率为83.08%。胃肠间质瘤、平滑肌瘤、异位胰腺和脂肪瘤、神经内分泌瘤EUS诊断准确率分别为81.67%、85.71%、80.00%、100.00%和100.00%,其比较差异无统计学意义(P>0.05)。EUS诊断不准确患者年龄≥60岁、BMI≥24kg/m 2、肿物直径>2cm比例分别为54.55%、50.00%和86.36%,明显高于EUS诊断准确患者,存在统计学差异(P<0.05),但在性别、病变位置、起源层次、病变类型等比较差异无统计学意义(P>0.05)。Logistic回归结果显示:年龄、BMI是胃黏膜下肿物EUS诊断准确率的影响因素,差异有统计学意义(P<0.05)。结论胃黏膜下肿物的小探头EUS准确率较高,其诊断受患者年龄、BMI的影响。 | 戚美娅 梁慧霞 刘谦 | 2023 | 现代消化及介入诊疗2023，28，8： | 0 |
