概括
第1周的肠道超声波 (IUS) 可以预测性结肠炎 (UC) 的长期治疗反应. 早期减少直肠壁厚度准确预测临床内镜缓解和粘膜改善.
科学领域:
- 胃肠病学 胃肠病学
- 医疗成像医学成像
- 炎症性肠道疾病研究研究
背景情况:
- 肠道超声波 (IUS) 被公认为用于评估性结肠炎 (UC) 的短期治疗反应.
- 早期IUS (6-14周前) 对UC的长期内镜结果的预测价值仍未得到充分探索.
- 治疗UC的先进疗法需要可靠的治疗疗效的早期指标.
研究的目的:
- 评价第1周内肠道静脉系统对接受高级治疗的UC患者长期临床内镜缓解 (CER) 和组织内镜粘膜改善 (HEMI) 的预测能力.
- 通过IUS测量直肠肠壁厚度的早期变化是否可以预测长期缓解和粘膜愈合.
主要方法:
- 一项涉及活跃UC患者的前性研究的后期分析.
- 在基线,第1周和第8周进行的IUS (transabdominal和transperineal)
- 长期CER和HEMI通过结肠镜 (>14周) 评估,使用梅奥内镜子分值和吉博斯评分.
- 用于评估IUS预测值的接收器操作特征 (ROC) 分析.
主要成果:
- 在第1周,在获得CER和HEMI的患者中观察到直肠肠壁厚度 (直肠BWT) 的显著减少.
- 在第1周的直肠BWT显示在预测CER (AUC0.75) 和HEMI (AUC0.79) 方面都具有很高的准确性.
- 在第8周的直肠BWT中,在实现或不实现缓解/改善的组之间没有显著差异.
结论:
- 在第一周通过IUS对直肠壁厚度的早期评估是用先进疗法治疗UC患者长期结果的有价值的预测指标.
- IUS提供了一种非侵入性方法,用于早期预测治疗成功,从而能够及时进行治疗调整.
- 这一发现支持第1周IUS在接受先进治疗的UC患者的管理中的实用性.

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

Assessment of the Rectum and Anus
402
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
