概括
与基于症状的"需要时"内镜相比,对巴雷特食道 (BE) 的定期内镜监测并没有改善存活率. 这项大型试验表明",需要时"内镜可能是管理BE患者的安全替代方案.
科学领域:
- 胃肠病学 胃肠病学
- 在瘤学瘤学.
- 临床试验 临床试验
背景情况:
- 巴雷特食道 (BE) 是已知的食道腺癌 (EAC) 的前体.
- 监视内镜是检测BE恶性进展的标准实践.
- BOSS试验是第一个随机对照试验,用于评估BE监测的有效性.
研究的目的:
- 为了比较每两年一次的监视内镜与每两年一次的监视内镜的有效性.
- 在-需要的需要.
- 用于巴雷特食道患者的内镜.
- 评估监测对总生存率,癌症特异性生存率和EAC诊断的影响.
主要方法:
- BOSS试验是一项随机对照试验,涉及109个英国中心的3453名患者.
- 患者被随机分配到每2年一次的监视内镜或每2年一次的监视内镜.
- 在-需要的需要.
- 根据症状进行内镜检查.
- 随访时间为至少10年,主要结果是整体存活率.
主要成果:
- 在监测和监测之间没有观察到总生存率 (HR,0.95;95% CI,0.82-1.10) 或癌症特异性生存率 (HR,1.01;95% CI,0.77-1.33) 的显著差异.
- 在-需要的需要.
- 群体. 群体. 团体.
- 在EAC诊断的时间或诊断时的癌症阶段没有显著差异.
- 与内镜相关的严重不良事件很少发生,并且在两组中都相似 (0.46%对0.41%).
结论:
- 对巴雷特食道的常规内镜监测并不能改善整体或癌症特异性存活率.
- 根据症状指导的"需要时"内镜似乎是低风险的BE患者的安全替代管理策略.
- 这些发现挑战了目前的监测指南,并表明了临床实践的潜在转变.

Barrett Esophagus-I: Introduction
46
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
84
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...

Endoscopic Procedures I: Esophagogastroduodenoscopy
40
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
152
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Upper GI Series: Barium Swallow
73
The Barium Swallow Study, or a Barium Esophagogram, is a diagnostic imaging method used to visualize the upper gastrointestinal (GI) tract, including the esophagus, stomach, and small intestine. It employs barium sulfate, a radiopaque contrast material, to provide clear images of the upper digestive system, helping to identify abnormalities, diseases, or structural issues.
Purpose and Procedure
Patients undergoing this procedure ingest a liquid containing barium sulfate with a chalky...

Endoscopic Procedures III: Video Capsule Endoscopy
61
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...
