目的 探讨放大内镜结合腺管开口分型对大肠粘膜病变性质的诊断价值。方法 放大内镜检查发现病变后 ,对病灶喷洒靓胭脂 ,观察病灶粘膜腺管开口形态 ,按Kudo分型作病灶性质判断 ,并与切除或活检组织作病理学比较。结果 在 194处病灶中 ,放大内镜诊断为炎性息肉、管状腺瘤、绒毛状腺瘤和大肠癌的病理符合率分别为 10 0 %、93 3 %、90 9%、10 0 % ,总病理符合率为 96 1%。结论 放大内镜对判断大肠病变性质有较高的病理符合率 ,可区分肿瘤与非肿瘤、良性与恶性肿瘤 ,预测癌的浸润深度 ,决定合适的治疗方式 ,具有较高的临床应用价值
Objective To explore the diagnostic value of magnifying endoscopic and ductal opening classification in the characterization of colorectal mucosal lesions. Methods After magnifying endoscopy, lesions were dissected, and the wounds were sprayed with rouge. Morphology of the mucosal gland opening was observed. Kudo classification was used to determine the nature of the lesion. The pathology was compared with that of resection or biopsy. Results Among the 194 lesions, the pathological coincidence rates of adenomatous polyps, tubular adenoma, villous adenoma and colorectal carcinoma were 10 0%, 93 3%, 90 9%, 100%, respectively Pathological coincidence rate of 96 1%. Conclusion The magnifying endoscopy has a high pathological coincidence rate for judging the pathological changes of large intestine, which can differentiate tumor from non-tumor, benign and malignant tumor, predict the depth of cancer invasion, determine appropriate treatment and have high clinical value
