概括
在结直肠内镜下粘膜切割 (ESD) 后的预防性剪切没有减少临床显著的延迟出血 (CSDB). 这一发现甚至适用于高风险患者,这表明常规关闭可能不必要.
科学领域:
- 胃肠病学 胃肠病学
- 内視鏡外科手術 內視鏡外科手術
- 手术并发症 手术并发症
背景情况:
- 临床显著的延迟出血 (CSDB) 是结肠直肠内镜下粘膜解剖 (ESD) 后的主要并发症.
- 利莫日出血评分 (LBS) 有助于识别患有CSDB风险较高的患者.
- 在结直肠ESD后预防CSDB的预防性剪切的必要性正在进行调查.
研究的目的:
- 评估完整的剪贴关闭在减轻结直肠ESD后的CSDB的有效性.
- 为了比较接受预防性剪切和没有接受预防性剪切的患者之间的CSDB率.
- 分析预防性剪切在高风险患者亚组和环境因素的影响.
主要方法:
- 从10个中心 (2019-2022) 收集的前性数据的回顾性分析,涉及结直肠ESD.
- 倾向性得分匹配 (PSM) 用于比较关闭和非关闭组之间的结果,以LBS风险因素进行调整.
- 对服用抗凝血剂的患者和高LBS分数的患者进行了亚组分析 (5-8).
主要成果:
- 总共分析了3142名患者 (1199名关闭,1943名非关闭),总体CSDB率为6.9%.
- 在关闭 (7.2%) 和非关闭 (6.9%) 组之间没有观察到CSDB率的显著差异 (P=0.66).
- PSM分析 (944个匹配病例) 和对高风险患者和抗凝剂使用者的子组分析也显示,预防性剪切后CSDB没有显著减少.
结论:
- 预防性剪切并没有显著降低结直肠ESD后CSDB的发病率.
- 该研究在高风险患者小组中没有发现任何益处,包括那些服用抗凝药的人.
- 由于缺乏已证明的有效性及其相关的环境影响,应重新考虑例行预防性剪切.

Endoscopic Procedures II: Colonoscopy
618
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:

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
