【摘要】 目的:探讨大肠息肉患者好发年龄、主要临床表现及息肉的发生部位、大小和病理类型及癌变规律。方法:对电子肠镜检查中检出的大肠息肉患者的临床表现、内镜及病理资料进行分析总结。结果:检查患者1030例,检出大肠息肉132例,检出率12.8%,其中男性78例,女性54例;好发年龄50~69岁,占59.1%;腺瘤性、炎性、增生性、幼年性息肉各占63.8%、23.7%、8.9%和3.6%;息肉部位分别为盲肠4.0%、升结肠9.8%、横结肠6.7%、降结肠4.5%、乙状结肠33.9%、直肠41.1%。132例患者中,便血46例,21例息肉直径大于1.5 cm者皆有便血;有4例发生癌变,癌变率3.0%,癌变息肉平均直径2.8 cm。结论:50~69岁大肠息肉发病率较高;主要临床表现为便血,息肉直径较大及局灶癌变者易出血,男性较女性更易患大肠息肉;息肉好发部位为左半结肠;病理类型以腺瘤性息肉、炎性息肉较常见;左半结肠、直径≥2.0 cm息肉容易癌变;内镜切除大肠息肉可预防息肉癌变。更多还原

【Abstract】 Objective: To study the clinical,enteroscopic and pathological characteristics of colorectal polyps and canceration rules.Methods:The clinical situations,enteroscopic manifestation and pathological characteristics of 132 cases of colorectal polyps were analyzed.Results:1030 cases had received enteroscopy in our hospital from 2004 to 2007 and the incidence of colorectal polyps was12.8%,including 78 men and 54 women.The rate of colorectal polyp was 59.1% in 50 to 69 years old persons.The rates of adenomatous,inflammatory,hyperplastic and juvenile polyps were 63.8%,23.7%,8.9% and 3.6%,respectively.Polypoid lesions were located at cecum(4.0%),ascending colon(9.8%),transverse colon(6.7%),descending colon(4.5%),sigmoid colon(33.9%),and rectum(41.1%).46 cases had hematochezia and 4 cases were found to show polypous canceration.Conclusion:50 to 69 year old people are easy to suffer from colorectal polyps.The incidence in the male is higher than that in the female and colorectal polyps occurs more in left colon than in the other parts.The common pathological type is adenomatous and inflammatory polyps.There is a high canceration of polyps in the left colon and ≥2.0 cm polyps.All of the colon polyps should be excised as soon as possible and undergo the pathological examination.Enteroscopic polypectomy is helpful to prevent colorectal polypous canceration.更多还原
