目的对比分析术前术后结直肠高级别上皮内瘤变病理结果,探讨其差别意义。方法对病理诊断为HGCIN的55例患者进行术前病理与术后病理对比、分析,总结其不一致可能的原因及对策。结果术后病理仅6例(10.9%)仍为高级别上皮内瘤变,其余均为腺癌。其中26例已有局部淋巴结转移,1例伴有肝转移。术前术后诊断的差异很大。结论诊断为HGCIN的病例绝大多数(89.1%)实际上是腺癌,部分已有局部淋巴结转移及远处转移,需积极处理。
Objective To compare and analyze preoperative and postoperative high-grade intraepithelial neoplasia of colorectal neoplasia pathology results to explore the significance of the difference. Methods 55 cases of pathological diagnosis of HGCIN were compared preoperative pathology and postoperative pathology, analysis, summarizes the possible causes and countermeasures. Results Postoperative pathology only 6 cases (10.9%) still high grade intraepithelial neoplasia, the rest are adenocarcinoma. 26 cases had local lymph node metastases, 1 case accompanied by liver metastases. The preoperative and postoperative diagnosis is very different. Conclusion The vast majority of cases diagnosed as HGCIN (89.1%) are actually adenocarcinomas, some of them have had local lymph node metastasis and distant metastasis, and should be actively treated.
