摘要
对纤维胃镜咬取的18例消化不良患者的十二指肠纹缘上皮微绒毛,进行了超微结构观察和图像分析研究。结果显示,7例吸收不良综合征患者的微绒毛平均长度、密度及表面积等均较11例非吸收不良综合征患者(胃炎5例、结肠炎6例)的微绒毛明显短和小,差异非常显著(P<0.01)。部分病例还显示有微绒毛长短不一、方向紊乱及花束样粘连等改变。病变轻重与临床表现基本相符,治疗好转者微绒毛病变改善。提示本病患者十二指肠微绒毛病变可基本代表小肠病变概貌。本文提出的吸收不良综合征临床诊断标准,亦经本资料证实有实用价值。
The ultrastructural changes and image analysis of duodenal striated epithelial mi-crovilli of 18 patients with dyspeptic were studied. The specimens were obtained by fibrogas-troscop biopsy. The result indicated that the e-varage length, density and surface areas of mi-crovilli in 7 patients with malabsorption syndrome were all markedly shorter and smaller than those in 11 patients with chronic gastritis or colitis (P<0. 01). In some cases of the 7 patients, the microvilli also showed no-uniform disorder of direction or flower-benchoid adhesin-lect. The degree of the microvillial abnormal i-ties conformed basally with the clinical represents. The pathological changes reduced with the heading of the disease . It sugest that, the basic pathological changes of the small intestinal mu-cosa may be represented by that of the duodenal mucosa of the patient with malabsorption syndrome. On the other hand, we proposed the clinical diagnostic criteria of malabsorption syndrome.
