OBJECTIVE
To evaluate the clinical value of magnifying endoscopy in diagnosis and treatment of colorectal benign neoplastic lesions.
METHODS
Seventy-eight colorectal lesions in 61 patients were examined with magnifying colonoscopy after indigo carmine dyeingìand pit pattern diagnosis was made for every lesion according to Kudos classification to differentiate neoplastic lesions from non-neoplastic lesions. The lesions were resected by endoscopic polypectomy and mucosectomy or surgical treatment. The diagnoses made by magnifying colonoscopy were compared with pathologic results.
RESULTS
The diagnostic sensitivity of magnifying endoscopy for neoplastic lesions was 98.4% and specificity was 85.7%. The overall accuracy for adenoma and early colorectal cancer was 96.2%. 89.7% of adenomatous lesions were treated by endoscopic resection.
CONCLUSION
The magnifying colonoscopy can provide instantaneous and accurate diagnosis of neoplastic lesions in colon and rectum,as well as minimally invasive treatment.
目的
评估放大内镜在结直肠良性肿瘤性病变诊断及治疗中的临床价值。
方法
对61例患者的78处结直肠病变行靛胭脂染色后放大结肠镜检查，依据工藤分类法对每个病变进行腺管开口分型诊断，以鉴别肿瘤性病变与非肿瘤性病变。病变采用内镜下息肉切除术、黏膜切除术或手术治疗。将放大结肠镜诊断结果与病理结果进行比较。
结果
放大内镜对肿瘤性病变的诊断敏感度为98.4%，特异度为85.7%。腺瘤及早期结直肠癌的总体诊断准确率为96.2%。89.7%的腺瘤性病变采用内镜下切除术治疗。
结论
放大结肠镜可对结直肠肿瘤性病变进行即时、准确诊断，并能实施微创治疗。
