目的:分析69例大肠息肉恶变的特点,探讨息肉恶变的相关因素。方法:选择经肠镜检查确诊的结直肠息肉恶变患者69例作为观察对象,分析患者年龄、息肉病理类型、息肉体积、位置与癌变的关系。结果:患者平均年龄(55.32±16.46)岁、息肉直径(1.76±0.48)cm,其中67例病理类型为腺瘤型息肉(管状腺瘤21例,绒毛状腺瘤37例,混合型腺瘤9例),2例为炎性息肉(继发于溃疡性结肠炎),位于直肠29例,乙状结肠18例,降结肠10例,升结肠5例,全结肠7例。结论:结直肠息肉恶变与其组织类型密切相关,息肉的体积和位置也有一定关系。
Objective: To analyze the characteristics of malignant colorectal polyps in 69 cases and to explore the related factors of malignant polyps. Methods: A total of 69 patients with colorectal polyposis malignancies diagnosed by colonoscopy were selected as the observation objects. The age, the pathological type of polyps, the volume of polyps, the location and the relationship with carcinogenesis were analyzed. Results: The average age of the patients was 55.32 ± 16.46 years old and the diameter of polyps was 1.76 ± 0.48 cm. Among them 67 cases were adenomatous polyps (tubular adenoma 21, villous adenoma 37, mixed adenoma 9 Cases), 2 cases of inflammatory polyps (secondary to ulcerative colitis), located in the rectum in 29 cases, sigmoid colon in 18 cases, descending colon in 10 cases, ascending colon in 5 cases, colon in 7 cases. Conclusion: The malignant transformation of colorectal polyps is closely related to its tissue type. The volume and location of polyps also have a certain relationship.
