摘要
对疑有下消化道病变的192例患者及41例正常对照者进行了逆行性回肠内镜检查与活检、其中19例患者回肠粘膜似有萎缩,内镜下呈淡红、灰黄或灰白色,失去光泽,暗红色血管清晰可见,从天鹅绒状变为平绒状.肠活检标本被标记印度墨汁,定向包埋,连续垂直切片。经过形态计量学观察发现17例回肠粘膜萎缩,同时被扫描电镜印证.
192 subjects with suspected lower intestinal disease and 41 normal volunteers were examined through retrograde ileoscopy with biopsy. In 19 of 192 subjects en-doscopically, ileal mucosa seemed to be atrophied, and presented pale red or greyish-yellow or greyishwhite colour. There was loss of sheen. The dark red twiggy vessels were distinct, and texture ranged from velvet to velveteen. Ileal biopsied specimens were arranged and marked with India ink on the mucosal surface, and serially sectioned. Morphometrically mucosal atrophy of distal ileum in 17 patients was found, and demonstrated by Scanning electron microscope simultaneously.
