变焦放大电子大肠镜对结-直肠隆起性病变的诊断价值

DIAGNOSTIC ASSESSMENT OF MAGNIFYING COLONOSCOPE TO PROMINENT COLORECTAL LESIONS

目的 :探讨变焦放大电子大肠镜在结 -直肠隆起性病变诊断中的应用价值。方法 :采用放大大肠镜配合局部病灶染色的方法 ,观察结 -直肠隆起性病变隐窝开口形态变化情况。结果 :变焦放大电子大肠镜配合局部病灶染色对结 -直肠隆起性病变的诊断与术后病理组织学检查的符合率为 88.2 4 % (45 / 5 1) ,其中对良性病变的诊断符合率为 94 .4 4 % (34/ 36 ) ,恶性病变的诊断符合率为 88.2 4 % (15 / 17)。结论 :变焦放大电子大肠镜对结 -直肠隆起性病变的诊断具有观察病变全面及与病理组织学诊断符合率高等优点 ,具有重要的临床应用价值。

Objective:To evaluate the diagnostic ability of magnifying colonoscope in prominent colorectal lesions.Method:The mucosal crypt patterns of colorectal neoplasia were observed under magnifying colonoscopy with local mucosa staining.Results:The prominent colorectal lesions visualized by magnifying colonoscope in 45 of the 51 cases were identical to those observed by histological method. The coincidence rate was 88.24% ,the coincidence rate of benign and malignancy lesion was 94.44%(34/36) and 88.24%(15/17) respectively. Conclusion:Magnifying colonoscope appears to provide a very important diagnositic ways for prominent colorectal lesions from the point of view of its mucosa detail's detection and high consistent rate with histological results.
