放大内镜对大肠粘膜病变的诊断价值

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

Value of magnifying endoscopy in the detection and diagnosis of colorectal lesion

Objective To evalulate the clinical value of magnifying endoscopy(ME)in combination with pit pattern in the detection and diagnosis of colorectal lesions.Methods Once the lesions were detected by ME,Indigo Carmine was sprayed,the pit pattern observed and the type of the lesion determined according to the Kudo' criteria for classification.The pathology diagnosis was as contrast.Results The accuracies of ME in detection of inflammatory polyps,tubular adenomas,villous adenomas or colorectal cancer were 100%,93.3%,90.9% and 100% respectively,as compared with those of the pathology outcomes.And the total accuracy was 96.1%.Conclusion ME examination, which appears to be sensitive in distinguishing the neoplasms from the non-neoplasms,or the benign from the malignant,can also be applied for predicting the depth of cancers and choosing the strategy of therapy.It is,therefore,of value to the detection and diagnosis of colorectal lesions.
