概括
大肠直肠癌 (CRC) 在阿曼正在上升,许多病例是早期发病的. 这项研究在50岁以下的症状成年人中发现了显著的晚期瘤,强调了对警报症状的及时结肠镜检查的必要性.
科学领域:
- 胃肠道学和瘤学
- 公共卫生 公共卫生
- 流行病学 流行病学
背景情况:
- 结肠直肠癌 (CRC) 是阿曼的主要恶性瘤,50岁之前早期发病的CRC (EOCRC) 的增加令人担忧.
- 缺乏有组织的查导致晚期症状诊断,需要评估结肠镜检查结果的年龄相关差异.
研究的目的:
- 评估与年龄相关的结肠镜检查结果差异和症状严重的成年人中晚期瘤风险.
- 在阿曼,为早期检测策略和查计划的制定提供信息.
主要方法:
- 来自两个高等医疗中心 (2018-2021) 的2041次结肠镜的横截面分析.
- 患者被分类为年龄<50岁和年龄≥50岁.
- 结果包括腺瘤检测率 (ADR),先进的前恶性病变 (APL),CRC和先进的结直肠瘤 (ACRN).
主要成果:
- 晚期瘤 (ACRN) 发生率在≥50岁 (13.3%) 的患者中明显高于<50岁 (5.9%) 的患者.
- 在年轻的成年人 (<50岁) 中,直肠出血和腹痛与ACRN有显著的关联.
- 尽管发病率较低,但在50岁以下的有症状的成年人 (5.9%ACRN,2.7%CRC) 中发现了大量的晚期瘤.
结论:
- 结直肠瘤存在与年龄相关的显著差异,50岁以下的症状成年人患有晚期疾病的负担显著.
- 对于年轻的成年人来说,如果出现像直肠出血和腹部疼痛这样的警报症状,迅速进行结肠镜评估至关重要.
- 需要进一步的前性查试验和成本效益分析,以确定最佳的查年龄门,并为阿曼的政策提供信息.

Endoscopic Procedures II: Colonoscopy
910
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Barrett Esophagus-I: Introduction
1.0K
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...
