摘要
胃内隆起性病变是胃镜检查过程中常见的病变,根据病变来源可分为黏膜组织来源、黏膜下组织来源及外源性压迫。常见胃黏膜组织来源病变有增生性息肉、胃底腺息肉、腺瘤等,黏膜下组织来源病变有胃肠道间质瘤、异位胰腺、脂肪瘤、胃囊肿、炎性纤维性息肉、胃肠道平滑肌瘤等,可统称为胃黏膜下肿瘤;外源性压迫有肝肿大、肝癌、胃壁外的脏器等所致。胃内隆起性病变临床表现缺乏特异性,其中胃底腺息肉、胃腺瘤、胃肠道间质瘤等病变具有恶变潜能。随着人们的饮食结构的改变、健康意识的提高及电子胃镜的广泛应用,胃内隆起性病变检出率及治愈率明显提高,对预防胃癌发生、发现早期胃癌和治疗早期胃癌有重要的临床意义。
Gastric protruding lesions are common during digestive endoscopic examination.According to the origin of lesions,they can be divided into mucosal layer derived,submucosal layer derived and extrinsic compression caused. Common mucosal originated lesions include hyperplastic polyps,gastric fundus polyps,gastric adenoma. Submucosal tissue originated lesions include gastrointestinal stromal tumors,ectopic pancreas,lipoma,gastric cysts,inflammatory fibrous polyps,which can be collectively referred to submucosal tumors. The extrinsic compression lesions may due to hepatomegaly,hepatocarcinoma and adjacent organs. Gastric protruding lesions are lack of significant clinical manifestations,however lesions like fundic gland polyps,gastric adenoma,gastrointestinal stromal tumors and some other lesions have malignant potential. Changing in people's diet,health awareness with the popularization of endoscopic examination,the detection rate and cure rate of gastric protruding lesions have dramatically improved,which lead to a better prevention of gastric cancer and early treatment of gastric cancer.
