概括
大型结直肠聚的冷切除比热切除更安全,显著减少不良事件. 然而,这种技术与较高的残留腺瘤率有关,需要进一步研究个性化治疗策略.
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
- 结肠直肠癌 预防 预防
背景情况:
- 内镜粘膜切除 (EMR) 是大型非形结直肠多 (≥20毫米) 的标准治疗方法.
- 对于这些息肉,冷切除与热切除 (使用切割/凝结电流) 的安全性和有效性仍在研究中,随机试验数据有限.
- 以前的建议表明,与热切除相比,冷切除可能会减少不良事件.
研究的目的:
- 为了在一项随机对照试验中比较冷内镜粘膜切除 (EMR) 与热EMR的大型非形结直肠多 (≥20毫米) 的安全性和有效性.
- 评估主要不良事件 (AEs) 的初级结局和二次结局,包括穿孔,后内镜出血,后多斑瘤综合征和残留腺瘤.
- 为了确定不良事件和残留腺瘤在大结直肠多的预测因素.
主要方法:
- 进行了一项涉及19个中心的多中心随机对照试验.
- 无支柱结直肠多≥20毫米被随机分配到冷EMR或热EMR中.
- 主要结局是主要不良事件 (穿孔或后内镜出血);次要结局包括后多斑瘤综合征和残留腺瘤.
主要成果:
- 主要不良事件发生在冷切除组的1.0%和热切除组的7.9% (P=.001).
- 穿孔率 (0%对3.9%,P=.007) 和内镜后出血率 (1.0%对4.4%,P=.040) 在感冒组明显较低.
- 冷切除 (23.7%) 后残留腺瘤的发生率比热切除 (13.8%) (P=.020) 高.
结论:
- 大型非形结直肠多瘤的冷切除明显比热EMR更安全,主要不良事件较少.
- 通过冷切除减少不良事件的好处是以更高的残留腺瘤率为代价.
- 需要进一步的研究来确定多体大小和组织学如何指导结直肠多体的个性化治疗方法.

Endoscopic Procedures II: Colonoscopy
82
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:

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
73
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.
