概括
在15mm以上的巴雷特食道癌症中优先进行内镜下粘膜剖析 (ESD),可显著改善R0切除率并减少复发. 这一策略提高了T1b疾病的短期存活率,支持更大的巴雷特癌症的常规ESD.
科学领域:
- 胃肠病学 胃肠病学
- 胃肠内镜检查 胃肠内镜检查
- 手术瘤学手术瘤学
背景情况:
- 瘤学原则主张在内镜切除中进行块式R0切除.
- 在巴雷特瘤中治疗性内镜切除适用于T1a和选择的早期T1b癌症.
- 对于内镜粘膜切除 (EMR) 和内镜亚粘膜解剖 (ESD) 的最佳病变选择仍在争论中.
研究的目的:
- 为了比较两个巴雷特癌症切除策略的瘤结果.
- 评估ESD-first方法用于15毫米以上的病变,与保留ESD用于晚期癌症的历史方法相比.
主要方法:
- 多中心回顾性观察性研究 (2004-2024年).
- 对比一种以ESD为首的战略 (2017-2024) 与一种选择性的ESD方法 (2004-2016).
- 评估结果:基底R0切除,治愈切除,复发和不良事件.
主要成果:
- 首先使用ESD的策略 (第二期) 显示了基底R0切除的改善 (91.2%与69.7%,p<0.001),特别是T1b病变 (81.9%与33.3%,p<0.001).
- 治疗切除增加 (30.5%对9.5%,p=0.043) 和复发减少 (23.6%对55.6%,p=0.043) 的T1b癌症与ESD-first.
- 在ESD中,无癌症2年生存率高于EMR (87.4%与50%相比,p=0.021);不良事件是罕见的和类似的.
结论:
- 优先考虑Barrett癌症>15mm的ESD可以增强R0切除并减少复发.
- 这一策略改善了T1b疾病的短期存活率.
- 建议在所有较大的巴雷特癌症中进行常规的ESD.

Barrett Esophagus-I: Introduction
642
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...

Barrett Esophagus-II: Clinical Manifestations and Management
802
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...
