回肠末段Crohn病(肉眼)


回肠末段Crohn病。虽然胃肠道的任何部位都可患Crohn病,但空肠和回肠末段尤易发。可见肠中部肠壁增厚、黏膜已经失去了规则的粘膜皱襞。浆膜表面有略带红色坚硬的脂肪组织已蔓延至其表面。浆膜的炎症导致了粘连。炎症病变呈阶段性不连续。
This portion of terminal ileum demonstrates the gross findings with Crohn's disease. Though any portion of the gastrointestinal tract may be involved with Crohn's disease, the small intestine--and the terminal ileum in particular--is most likely to be involved. The middle portion of bowel seen here has a thickened wall and the mucosa has lost the regular folds. The serosal surface demonstrates reddish indurated adipose tissue that creeps over the surface. Serosal inflammation leads to adhesions. The areas of inflammation tend to be discontinuous throughout the bowel.
