目的提高结直肠癌活检阳性率。方法收集我院44例结直肠疾病患者的活检及其组织细胞学检查的临床资料进行分析。结果经活检组织学诊断,发现结直肠癌为19例,重度不典型增生8例,异性细胞1例,绒毛状腺瘤伴部分腺上皮增生4例,管状腺瘤2例,增生性息肉1例,慢性黏膜炎7例,粘膜黑变1例。确诊结直肠癌阳性率43.18%,癌前病变率34.09%。结论活检钳型号的选择、活检钳操作技术、活检部位的选定、结合NBI可利于靶向活检,为临床治疗给予更有力的支持。
Objective To improve the positive rate of colorectal cancer biopsy. Methods We collected 44 cases of colorectal diseases in our hospital biopsy and histological examination of the clinical data were analyzed. Results According to histological examination of biopsy, there were 19 cases of colorectal cancer, 8 cases of severe dysplasia, 1 case of heterosexual cells, 4 cases of villous adenoma with partial glandular hyperplasia, 2 cases of tubular adenoma, 1 case of proliferative polyp , Chronic mucositis in 7 cases, mucosal blackening in 1 case. The positive rate of diagnosed colorectal cancer was 43.18% and the rate of precancerous lesions was 34.09%. Conclusion The selection of biopsy forceps, the biopsy forceps operation technique, the selection of biopsy site and the combination of NBI can be used for targeted biopsy, giving more support for clinical treatment.
