【摘要】 本文统计的163例胃双重对比造影片中,无胃小区显示者37例,有胃小区显示者126例。根据胃小区及胃小沟的形态,主要是胃小沟的形态,可将胃小区分成Ⅰ、Ⅱ、Ⅲ及Ⅳ型,其中Ⅰ型又分成Ⅰ_a、Ⅰ_b两亚型。 在无胃小区显示组中,14.3％的胃粘膜活检为正常,12.5％为轻度浅表炎症,其余为慢性浅表炎症;胃窦部显示有胃小区者,其病理活检均有慢性炎症存在,因此胃窦部胃小区的出现是X线诊断慢性胃炎的可靠依据。 胃小区从Ⅰ型到Ⅳ型,其粘膜炎症改变、肠上皮化生及固有腺体萎缩等病理变化,也由轻到重而逐渐增多。更多还原

【Abstract】 Of the 163 cases, 37 cases demonstrated no gastric area pattern on the films of double contrast radiogiography of stomach; the others, 126 cases, showed the gastric area patterns on the films. The patterns of gastric area in Antrum can be classified into 4 types-Ⅰ, Ⅱ, Ⅲ and Ⅳ with type Ⅰ further classified into 2 subtypes-Ia and Ib, depending upon the forms of the gastric area and groove, mainely upon the forms of groove. In the cases which did not demonstrate the gastric area pattern on the films, the pathological study of the biopsies revealed that 14.3％ were normal, slight superficial inflammation was found in 12.5％ and superficial inflammation in the others. In all the cases which demonstrated gastric area patterns on the films, the biopsies of gastric mucosa showed superficial inflammation,therefore the appearance of gastric area in Antrum on the X-ray films is a reliable basis for the diagnosis of chronic superficial gastritis by X-ray.With the types of gastric area from Ⅰ to Ⅳ the degree of inflammation, intestinal metaplasia and atrophy of proper gland in gastric mucosa was showed from slight to obvious in pathological study.更多还原
