目的 分析肠镜活检诊断为结直肠高级别上皮内瘤变的临床病理特征及外科治疗对策.方法 对2005年1月-2012年12月收治经内镜活检病理诊断为高级别上皮内瘤变的结直肠肿瘤患者82例的临床资料进行回顾性分析.71例行根治性结直肠癌手术,其中包括1例扩肛多次局切后术中病理补充行miles术,其他3例行单纯扩肛肿瘤切除术,8例行姑息性肿瘤切除术.将术后诊断与肠镜活检诊断进行比较分析.结果 术后病理3例(3.7%)仍为高级别上皮内瘤变,肿瘤直径1~3 cm,平均1.5 cm;其余79例(96.3%)证实为黏膜下层浸润性腺癌,肿瘤直径1 ~11 cm,平均4.7 cm,两组肿瘤最大直径差异有统计学意义(P<0.01).Kappa一致值为0.104,术前术后差异较大,一致性较差.统计分析显示肿瘤癌变与大小和浸润深度相关.证实为腺癌的79例中已有8例出现肝转移,31例(39.2%)有局部区域性淋巴结转移;33例直肠肿瘤中(包括1例多原发性肿瘤)有30例(90.9%)术后病理证实为腺癌.结论 要重视结直肠上皮内瘤变的病理诊断,诊断为高级别上皮内瘤变的肿瘤患者绝大多数已存在浸润性癌,甚至有区域性淋巴结转移及远处转移.如肿瘤位置不涉及保肛的问题,结直肠肿瘤直径大于3 cm者,应首选作病变肠段的切除,术中病理诊断为浸润性腺癌,则应行根治性手术.对于低位直肠肿瘤应当多次内镜活检和或扩肛肿块切除后再决定治疗方案.
目的 分析腸鏡活檢診斷為結直腸高級彆上皮內瘤變的臨床病理特徵及外科治療對策.方法 對2005年1月-2012年12月收治經內鏡活檢病理診斷為高級彆上皮內瘤變的結直腸腫瘤患者82例的臨床資料進行迴顧性分析.71例行根治性結直腸癌手術,其中包括1例擴肛多次跼切後術中病理補充行miles術,其他3例行單純擴肛腫瘤切除術,8例行姑息性腫瘤切除術.將術後診斷與腸鏡活檢診斷進行比較分析.結果 術後病理3例(3.7%)仍為高級彆上皮內瘤變,腫瘤直徑1~3 cm,平均1.5 cm;其餘79例(96.3%)證實為黏膜下層浸潤性腺癌,腫瘤直徑1 ~11 cm,平均4.7 cm,兩組腫瘤最大直徑差異有統計學意義(P<0.01).Kappa一緻值為0.104,術前術後差異較大,一緻性較差.統計分析顯示腫瘤癌變與大小和浸潤深度相關.證實為腺癌的79例中已有8例齣現肝轉移,31例(39.2%)有跼部區域性淋巴結轉移;33例直腸腫瘤中(包括1例多原髮性腫瘤)有30例(90.9%)術後病理證實為腺癌.結論 要重視結直腸上皮內瘤變的病理診斷,診斷為高級彆上皮內瘤變的腫瘤患者絕大多數已存在浸潤性癌,甚至有區域性淋巴結轉移及遠處轉移.如腫瘤位置不涉及保肛的問題,結直腸腫瘤直徑大于3 cm者,應首選作病變腸段的切除,術中病理診斷為浸潤性腺癌,則應行根治性手術.對于低位直腸腫瘤應噹多次內鏡活檢和或擴肛腫塊切除後再決定治療方案.

Objective To analyze the clinical and pathological characteristics and its surgical management strategy for colorectal high-grade intraepithelial neoplasia (HGIN).Methods Eighty-two cases with colorectal tumors diagnosed as colorectal HGIN based on colonoscopic biopsy between January 2005 and December 2012 were enrolled in the study.The clinicopathological data of all the patients was collected and analyzed.Of the 82 cases,71 cases had radical colorectal surgery,1 cases had Miles operation after previous transanal excisions,3 had transanal local excisions,8 cases had palliative surgery.The surgical specimens were all examined pathologically and compared with the preoperative diagnosis of colonoscopic biopsy of all the patients.Results Three cases (3.7%) were pathologically diagnosed as high-grade intraepithelial neoplasia,their average diameter was 1.5 cm.The other 79 (96.3%) cases were diagnosed as adenocarcinoma,with an average diameter of 4.7 cm.The difference in tumor size was statistically significant (P < 0.01).Comparison of pre-and post-operative specimens showed poor consistency,the Kappa value was O.104.Significant analysis showed a correlation between cancerous change to tumor size and depth of invasion.In the 79 cases confirmed as adenocarcinoma,liver metastasis occurred in 8 cases,regional lymph nodes metastasis in 31 cases (39.2%).Of the 33 cases with rectal tumors,30 cases (90.9%) were pathologically diagnosed as adenocarcinoma after operation.Conclusions Much attention should be payed to the pathological diagnosis in colorectal intraepithelial neoplasia,especially in the HGIN.We have found that of the cases first diagnosed as HGIN,approximately 96.3% already have invasion adenocarcinoma.Most cases had reginonal lymph nodes metastasis.Liver metastasis had been occurred.thus active surgical measures should be taken.If the location of the tumor was not involved to anal sphincter,or cases with tumors larger than 3 cm was diagnosed,in highly suspected cases with malignant potiential,radical surgery is recommended.For tumors located at the lower rectum,the final decision should be made only after repeated endoscopic or transanal biopsy.
