摘　　要：目的:探讨少见部位胃粘膜异位的诊断及鉴别诊断。方法:收集我院2008年12月～2012年3月,经胃镜下取检、病理证实的少见部位胃粘膜异位33例患者的病历资料,分析其病变的形态、大小及病理组织异型性程度。结果:胃粘膜异位十二指肠者多位于球部,占32例;最大者直径可达1.5cm;约6.6%(2/32)发生癌前病变。异位于直肠者1例,以便血来诊,应与直肠癌鉴别。结论:胃粘膜异位十二指肠及直肠因多发癌前病变或与癌形态相似,从临床及病理均应注意与肿瘤鉴别。Objective：To explore diagnosis and differential diagnosis of ectopic gastric mucosa in rare loca- tions.Methods：A total of 33 cases of ectopic gastric mucosa in rare locations were taken in the hospital from December 2008 to March 2012 through gastric endoscope,proven pathologically were collected.The morpholo- gy,size and degree of tissue heterogeneity of specimen were analyzed.Results：Ectopie gastric mucosa in duo- denum oeeured in the bulb for 32 cases,largest diameter of 1.5cm,with 6.6%（2/32）developing precancerous pathological change.Ectopic gastric mucosa in rectum was 1 case,presents with hematochezia,should be differentiated from rectal caneer.Conclusion：Eetopic gastric mucosa in duodenum and rectum should be differentiat- ed from tumors both clinically and pathologically,due to multiple precancerous pathological changes or similarities in morphology.
