Gastric polyps are usually asymptomatic lesions incidentally discovered during endoscopy.
To study the frequency of different types of gastric polyps in our population and their possible association with other factors.
Retrospective study of gastroscopies performed in a tertiary hospital over a ten-year period. Demographics, medical history, indication for gastroscopy and morphological and histological characteristics of polyps were collected.
Gastric polyps were found in 827 out of 41253 (2%) reviewed gastroscopies, corresponding to 709 patients. Mean age was 65.6 years, and 62% were female. 53.9% of patients had multiple polyps. The most common location was the fundus and 83.3% were smaller than 1cm. Histopathology was obtained in 607 patients: hyperplastic polyps were the most common (42.8%), followed by fundic gland polyps (37.7%). Factors independently associated with hyperplastic polyps were age and single polyp, size ≥6mm and location other than fundus. In contrast, fundic gland polyps were associated with reflux and multiple polyps, size <6mm and located in fundus. Adenomas were independently associated with single polyp.
Fundic gland and hyperplastic polyps are the most common in our population and have characteristic features that can guide histological diagnosis. With single polyps it is advisable to take biopsies to rule out adenoma.
胃息肉通常是在内镜检查时偶然发现的无症状病变。
研究我们人群中不同类型胃息肉的发生频率及其与其他因素的可能关联。
对一家三级医院在十年期间进行的胃镜检查进行回顾性研究。收集了人口统计学资料、病史、胃镜检查指征以及息肉的形态和组织学特征。
在41253例接受检查的胃镜病例中，发现827例（2%）有胃息肉，对应709例患者。平均年龄为65.6岁，62%为女性。53.9%的患者有多个息肉。最常见的部位是胃底，83.3%的息肉小于1cm。607例患者获得了组织病理学结果：增生性息肉最为常见（42.8%），其次是胃底腺息肉（37.7%）。与增生性息肉独立相关的因素是年龄、单个息肉、大小≥6mm以及非胃底部位。相比之下，胃底腺息肉与反流、多个息肉、大小<6mm以及位于胃底有关。腺瘤与单个息肉独立相关。
胃底腺息肉和增生性息肉在我们的人群中最为常见，并且具有可指导组织学诊断的特征。对于单个息肉，建议进行活检以排除腺瘤。
