作者复习了医院外科所有诊断为结肠溃疡患者的病史资料后,26例有经内镜、X线、手术或尸检诊断的结肠侵蚀性病变,并有可供研究的组织病理学的材料。糜烂和溃疡的区分在于病变未或已穿越粘膜肌层。急性期病变指病变周围无上皮和间质反应,而慢性病变则病变复盖有肉芽组织上有或无再生上皮、成纤维细胞增生及或纤维化。 After reviewing all medical records of patients with colon ulcer in hospital surgery, the authors reviewed 26 patients with colon-erosive lesions diagnosed by endoscopy, X-ray, surgery or necropsy and has available histopathological materials for study. The distinction between erosions and ulcers is that the lesion has not crossed or has crossed the muscularis mucosa. Acute lesions refers to the lesions around the absence of epithelial and interstitial reactions, and chronic lesions are covered with granulation tissue with or without regenerative epithelium, fibroblast proliferation and or fibrosis.
