概括
下一代测序 (NGS) 改善了胆管刷中的恶性瘤检测,提供了比单独的形态学更高的灵敏度. 虽然对临床决策的影响有限,但NGS在诊断胆管狭窄方面显示出未来的希望.
科学领域:
- 胃肠病学和肝病学
- 在瘤学瘤学.
- 分子诊断学 分子诊断学
背景情况:
- 胆管狭窄通常会带来诊断挑战,传统细胞学在识别恶性瘤方面存在局限性.
- 下一代测序 (NGS) 为诊断这些复杂病例提供了提高敏感性的潜在解决方案.
研究的目的:
- 评估NGS在对可疑胆管狭窄的胆管刷和活检进行分类时的附加值.
- 评估NGS结果对临床决策 (CDM) 的影响.
主要方法:
- 一个回顾性单中心队列研究包括106名患者 (109个样本) 从2019-2022.
- 在细胞学或组织学胆汁样本上进行了形态解释和NGS.
- 单独的形态学与NGS形态学的灵敏度和特异性被计算为刷子和活检.
主要成果:
- 在胆道刷中,NGS提高了对恶性瘤检测的灵敏度,从56%提高到78%,同时保持了高特异性 (94%).
- 对于胆管活检,单独的形态学具有67%的灵敏度和67%的特异性,NGS并没有显著改变这些指标.

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...
