目的 :比较大肠息肉电切前活检与电切后息肉组织的临床病理状况。方法 :回顾 5年间在我院接受大肠息肉电切的病例 ,对比分析每一病例电切前、后的临床报告及病理诊断 ,要求 :电切前后的病理来源于同一息肉 ;对多次电切病例只取第 1次进入病例分析 ;多发息肉患者取第 1枚电切息肉入组 ,其余排除 ;去除电切前活检已有癌变的病例。结果 :在 2 2 0例病例中符合要求的病例共 1 2 0例 ,年龄 59.8± 1 3 .3 ,其中男性占65 .8% ;活检和电切病理诊断不符合率为 33 .3 % (40 / 1 2 0 ) (P <0 .0 1 ) ;活检和电切分别诊断腺瘤性息肉 88例(73 .3 % )和 1 0 0例 (83 .3 % ) ,其中不典型增生分别有 2 9例 (33 .0 % )和 46例 (46 .0 % ) (P <0 .1 ) ;电切后发现5例腺瘤性息肉癌变 ,占 5 % (5/ 1 0 0 ) ,全部来源于 2 7例绒毛状腺瘤 (占其中 1 8.5 % ) ;活检诊为炎性息肉和增生性息肉的病例 ,电切后分别有 60 % (1 5/ 2 5)和 4/ 7被诊断为其它息肉类型 ;电切后发现活检未曾诊断的幼年性息肉 2例、间质瘤 2例、平滑肌瘤 1例 ;绒毛状腺瘤的直径较大 ,为 1 .43± 0 .58cm ,其余各型息肉直径平均为 1cm左右 ;癌变息肉直径最大 ,达 1 .8± 0 .57cm ,其最小直径是 1cm。结论 :大肠息肉电切前后的临床病理存在较大差异 ,活检有?
Objective: To compare the clinicopathological features of polyp tissue after biopsy and resection of polyp. Methods: To review the cases of colorectal polyp resection in our hospital during the past 5 years, to compare the clinical reports and pathological diagnosis of each case before and after the transurethral resection. The requirements are as follows: the pathology before and after the resection is from the same polyp; Only the first case into the case analysis; polyp polyp patients take the first piece of resection polyp into the group, the rest excluded; removal of biopsy before the cut has been the case of cancer. Results: Of the 220 cases, 120 cases were eligible, with a mean age of 59.8 ± 13.3%, of whom 65.8% were male; the non-coincidence rate of biopsy and electrosurgical diagnosis was 33.3% ( (P <0.01). There were 88 cases (73.3%) and 100 cases (83.3%) of adenomatous polyps diagnosed by biopsy and electrosurgical excision, respectively, of which dysplasia There were 29 cases (33.0%) and 46 cases (46.0%) of them (P <0.01). After resection, 5 cases of adenomatous polyps were found to be cancerous, accounting for 5% (5/100) All of them originated from 27 cases of villous adenoma (accounting for 8.5% of them). Biopsy showed inflammatory polyps and hyperplastic polyps. After the resection, 60% (15/2 5) and 4/7 Diagnosed as other types of polyps; after resection found no biopsy of juvenile polyps in 2 cases, 2 cases of stromal tumors, 1 cases of leiomyoma; villous adenoma diameter larger, 1.43 ± 0 .58 cm, The remaining types of polyps average diameter of about 1cm; cancerous polyps the largest diameter, up to 1.8 ± 0.57cm, the minimum diameter is 1cm. Conclusion: There is a big difference in the clinicopathological features of the polyps before and after resection of the polyps.
