228例大肠高危腺瘤性息肉的回顾性分析

目的探讨大肠高危息肉的内镜和病理特征,为内镜随访监测提供依据。方法按2006年美国大肠高危息肉判断标准,回顾性分析837例大肠息肉患者的临床表现及内镜、病理资料。结果发现结肠息肉患者1028例,大肠息肉的检出率为9.15%,其中病理资料完整者837例,男性515例,女性322例。腺瘤性息肉420例,占50.18%,其中管状腺瘤260例、绒毛状腺瘤99例、混合性腺瘤61例。非腺瘤性息肉417例,其中增生性息肉110例、炎性息肉307例。腺瘤性息肉患者中息肉数目≥3个71例,息肉直径≥1cm共236例。腺瘤性息肉患者中息肉癌变率为10.20%。剔除60例腺瘤癌变患者后,高危性腺瘤228例,低危性腺瘤132例。该部分息肉恶变情况有待今后随访得出相应结果。结论大肠高危息肉具有一定的内镜和病理特征,对大肠息肉切除后的规范筛查、诊断和合理随访具有指导意义。

Retrospective analysis of 228 colorectal advanced adenomas polyps

Objective To investigate the endoscopic and pathologic characteristics of colorectal advanced adenomas for the appropriate of surveillance colonoscopy.Methods According to the guidelines for colonoscopy surveillance after polypectomy,the clinic,endoscopic and pathologic characteristics of 228 colorectal advanced adenomas polyps were analyzed retrospectively.Results The incidence of colorectal polyps was 9.15%,including 515 men and 322 women.The number of colorectal adenomas polyps was 420(50.18%),including tubular adenomas(n=260),tubulovillous adenomas(n=61),and villous adenomas(n=99).The number of colorectal non-adenomas polyps was 417,including hyperplastic polyps(n=110),inflammantory polyps(n=307).In the colorectal adenomas polyps,the number of adenomas more than ≥3 was 71,adenoma size larger than 1 cm was 236.The incidence of colorectal cancer in patients with adenomatous polyps was 10.20%.People at higher risk adenomas was 228 and people at lower risk adenomas was 132.Conclusion Characteristics of colorectal advanced adenomas polyps were provided for the appropriate of surveillance colonoscopy of postpolypectomy.
