Colorectal polyps are structures that project from the surface of the mucosal layer of the large intestine. They are classified as neoplastic or non-neoplastic. Early detection of pre-neoplastic lesions is important for preventing colorectal cancer. These can be resected so as to decrease the morbidity and mortality rates. Colonoscopy is the gold-standard procedure for diagnosing and resecting precursor lesions.
To evaluate the epidemiological, endoscopic and histological aspects of endoscopic resection of lesions of the colon and rectum at a training center.
A search was conducted in the database of our institution covering the period from January 2011 to July 2014. Cases that underwent endoscopic resection of polyps and/or colorectal lesions were selection. The following variables were defined: general data on the patients (age, gender and indication from the examination) and data on the polypoid lesion (number, histological type and topographic distribution).
678 lesions were identified in 456 examinations. Regarding sex, 242 (53.1%) were female and 214 (46.9%) were male. The mean age was 64.54 years, with extremes of 5 and 94 years. The most frequent locations were the rectum (21%) and sigmoid (20%). Histologically, 34.7% were hyperplastic polyps and 58.9% were adenomatous polyps, of which 74.1% were tubular, 10.6% tubulovillous, 2% villous and 13% indeterminate; and 1.7% were adenocarcinomas. In 65.4% of the cases, the examination showed that only one polyps was present, while 34.6% had two or more lesions.
In our clinic, with a mean of 250 examinations/month, the parameters evaluated were compatible with the results reported in the literature.
结直肠息肉是从大肠黏膜层表面突出的结构。它们被分类为肿瘤性或非肿瘤性。癌前病变的早期检测对于预防结直肠癌很重要。这些病变可以切除以降低发病率和死亡率。结肠镜检查是诊断和切除前驱病变的金标准程序。
评估一家培训中心对结肠和直肠病变进行内镜切除的流行病学、内镜和组织学方面。
在我们机构的数据库中进行搜索，涵盖2011年1月至2014年7月期间。选择接受息肉和/或结直肠病变内镜切除的病例。定义了以下变量：患者的一般数据（年龄、性别和检查指征）以及息肉样病变的数据（数量、组织学类型和地形分布）。
在456次检查中识别出678个病变。关于性别，女性242例（53.1%），男性214例（46.9%）。平均年龄为64.54岁，年龄范围为5岁至94岁。最常见的部位是直肠（21%）和乙状结肠（20%）。组织学上，34.7%为增生性息肉，58.9%为腺瘤性息肉，其中74.1%为管状，10.6%为管状绒毛状，2%为绒毛状，13%为不确定型；1.7%为腺癌。在65.4%的病例中，检查显示仅存在一个息肉，而34.6%有两个或更多病变。
在我们的诊所，平均每月进行250次检查，评估的参数与文献报道的结果相符。
