Abstract

Background and Aims: Limited information is available on the frequency of advanced adenomas in diminutive colon polyps. Thus, this study aimed to investigate the pathological characteristics and the frequency of high-grade dysplasia in diminutive colorectal polyps in individuals referred to colonoscopy examination in Kermanshah, Iran. Materials and Methods: Demographics characteristics, location and diameter of the polyp, histological assessment of the polyps, grade, and others were retrieved from colonoscopy reports. Results and Conclusions: During the study period, 250 diminutive colorectal polyps were detected. The histological assessment showed that 36.4% were adenomatous, 32.8% were hyperplastic, and 30.8% were inflammatory polyps. Only two diminutive polyps (0.8%) had high-grade dysplasia, and the frequency of adenocarcinoma in our study was 0.4%. Besides, the frequency of adenomatous polyps was higher in the proximal versus the distal colon. These findings emphasize the urgent need for a colorectal cancer screening plan in the Iranian population to improve therapeutic outcomes.
伊朗西部一家教育治疗医院接受结肠镜检查患者的小结肠息肉特征
背景和目的:关于小型结肠息肉中晚期腺瘤的发生率的信息有限。因此,本研究旨在调查在伊朗Kermanshah进行结肠镜检查的个体中小型结直肠息肉的病理特征和高度发育不良的频率。材料和方法:从结肠镜检查报告中检索人口统计学特征、息肉的位置和直径、息肉的组织学评估、分级等。结果与结论:研究期间共检出结肠直肠小息肉250例。组织学检查显示:腺瘤36.4%,增生性32.8%,炎性息肉30.8%。在我们的研究中,只有两个小息肉(0.8%)有高度不典型增生,腺癌的发生率为0.4%。此外,性腺瘤性息肉在近端结肠的发生率高于远端结肠。这些发现强调了在伊朗人群中制定结直肠癌筛查计划以改善治疗效果的迫切需要。
