【摘要】：目的:分析胃息肉與窄帶成像結(jié)合放大內(nèi)鏡(NBI-ME)特點(diǎn)及其與幽門螺桿菌(H.pylori)感染、背景黏膜之間的關(guān)系,并提供有價(jià)值的信息來預(yù)測(cè)胃息肉的病理類型,判斷病變良惡性,指導(dǎo)靶向活檢。方法:收集336例胃息肉患者的一般臨床特點(diǎn)、內(nèi)鏡及病理資料,分析不同病理類型胃息肉在發(fā)生年齡上、胃內(nèi)分布上的不同,并探討336例胃息肉與背景黏膜的關(guān)系、97例胃息肉與H.pylori感染的情況及103例胃息肉在NBI-ME下的表現(xiàn)。用統(tǒng)計(jì)學(xué)方法進(jìn)行數(shù)據(jù)分析,計(jì)量資料以(?)表示,計(jì)數(shù)資料以百分率表示,構(gòu)成比資料比較采用χ~2檢驗(yàn),當(dāng)P0.05時(shí),認(rèn)為有統(tǒng)計(jì)學(xué)意義。結(jié)果:胃息肉常見于40到70歲之間;女性較男性多見;男女比為1:2.61。內(nèi)鏡下表現(xiàn):以單發(fā)多見;其發(fā)生部位以胃體、胃底為主;直徑多≤0.5cm;山田Ⅰ型和Ⅱ型占大多數(shù)(71.72%)。胃息肉病理類型以胃底腺息肉和增生性息肉常見,占胃息肉總數(shù)的絕大部分(89.29%),其中胃底腺息肉主要見于胃體和胃底,而增生性息肉發(fā)生部位較廣,兩者在胃內(nèi)分布不同,具有統(tǒng)計(jì)學(xué)意義。在發(fā)生年齡上,胃底腺息肉和增生性息肉之間無統(tǒng)計(jì)學(xué)意義。增生性息肉的H.pylori感染陽性率為73.17%,胃底腺息肉的H.pylori感染陽性率為40.48%,兩者之間具有統(tǒng)計(jì)學(xué)差異。在息肉背景黏膜表現(xiàn)中,胃底腺息肉背景黏膜表現(xiàn)為慢性非萎縮性胃炎者占95.35%,增生性息肉背景黏膜表現(xiàn)為慢性萎縮性胃炎者占27.34%,兩者之間有統(tǒng)計(jì)學(xué)差異。在NBI-ME下,腺瘤性息肉的微細(xì)黏膜結(jié)構(gòu)為長條狀或脊?fàn)?微血管形態(tài)為密集形或中央形。炎性息肉的微細(xì)黏膜結(jié)構(gòu)為長條狀,微血管形態(tài)為密集形。胃底腺息肉和增生性息肉的微細(xì)黏膜結(jié)構(gòu)分別以圓點(diǎn)狀(83.72%)和長條狀(84.45%)多見,微血管形態(tài)分別以蜂巢形(83.72%)和密集形(84.45%)多見,組合模式分別以圓點(diǎn)狀+蜂巢形(83.72%)、長條狀+密集形(82.22%)多見,且兩者在圓點(diǎn)狀和長條狀的微細(xì)黏膜結(jié)構(gòu)中、在蜂巢形和密集形的微血管形態(tài)中、在圓點(diǎn)狀+蜂巢形、長條狀+密集形的組合模式中均具有統(tǒng)計(jì)學(xué)差異。結(jié)論:胃底腺息肉好發(fā)于胃體和胃底,而增生性息肉發(fā)生部位較廣;增生性息肉較胃底腺息肉的幽門螺桿菌感染陽性率高;內(nèi)鏡下胃底腺息肉的背景黏膜多表現(xiàn)為慢性非萎縮性胃炎,而增生性息肉的背景黏膜表現(xiàn)為慢性萎縮性胃炎者較胃底腺息肉者多。在NBI-ME下,胃底腺息肉和增生性息肉的表現(xiàn)不同。
[Abstract]:Objective: to analyze the characteristics of gastric polyp and narrowband imaging combined with magnifying endoscopy (NBI-MEA) and its relationship with H. pylori infection and background mucosa, and to provide valuable information to predict the pathological types of gastric polyps and to judge the benign and malignant lesions. Guide targeted biopsy. Methods: the general clinical features, endoscopic and pathological data of 336 patients with gastric polyps were collected and analyzed. The relationship between gastric polyps and background mucosa was discussed. 97 cases of gastric polyps and H.pylori infection and 103 cases of gastric polyps under NBI-ME were studied. Statistical analysis and measurement of data The count data was expressed as a percentage, and the composition ratio was compared with 蠂 ~ 2 test. When P0.05, it was considered to have statistical significance. Results: gastric polyps were common between 40 and 70 years of age; women were more common than men, and the ratio of men to women was 1: 2.61. Under endoscopy, most of them were single, the main site was gastric body and fundus, the diameter was less than 0.5 cm, and Yamada type 鈪，
