概括
在结直肠内镜下粘膜解剖 (ESD) 后预防性伤口关闭显著减少延迟出血,特别是在大或直肠病变时. 这种技术不会增加穿孔或ESD后凝血综合征 (PECS) 的风险.
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
- 在瘤学瘤学.
背景情况:
- 结肠直肠内镜下粘膜切割 (ESD) 提供瘤的治愈切除,但有延迟出血的风险.
- 在结直肠ESD后预防性伤口关闭的有效性尚未得到充分证实.
- 这项研究系统地审查和元分析数据,以评估关闭的有效性和确定高风险患者子组.
研究的目的:
- 评估预防性伤口关闭在减少结肠直肠ESD后延迟出血的有效性.
- 为了比较关闭和非关闭集团之间的结果.
- 为了确定与增加出血风险相关的特定患者或病变特征.
主要方法:
- 一个系统的审查和元分析,遵循PRISMA 2020指南.
- 包括在2025年9月之前搜索的结直肠ESD后关闭的随机和比较队列研究.
- 主要结局:延迟出血;次要结局:穿孔和ESD后凝血综合征 (PECS). 聚合赔率比率 (ORs) 使用随机效应模型进行计算.
主要成果:
- 分析了九项研究 (n=2404). 预防性关闭显著减少了延迟出血 (OR 0.324).
- 这种益处在较大的病变 (≥3厘米) 和研究中具有较高比例的直肠手术 (≥25%) 的研究中更为明显.
- 封闭没有显著影响穿孔率 (OR 1.142) 或PECS (OR 0.723).
结论:
- 结直肠ESD后的预防性关闭有效减少延迟出血,特别是在大型瘤和直肠病变中.
- 该程序似乎不会增加穿孔或PECS的风险.
- 在高风险病例中选择性地应用关闭可能会优化患者的治疗结果并减少并发症.

Clinical Applications of Epidermal Stem Cells
3.4K
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Esophageal Varices-II: Clinical Features and Management
688
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
