|September 5, 2025
概括
在不增加出血风险的情况下,直肠印梅他素有效地预防ERCP后胰腺炎 (PEP). 当与胰腺支架一起使用时,它的有效性会增强,尽管研究偏差值得考虑.
科学领域:
- 胃肠病学和肝病学
- 临床药理学
- 医疗干预
背景情况:
- 急性胰腺炎是内镜逆行胆瘤学 (ERCP) 后的一个严重并发症.
- 目前用于预防ERCP后胰腺炎 (PEP) 的策略有限.
- 正在研究使用直肠内作为PEP的预防措施.
研究的目的:
- 通过更新的元分析来评估直肠内素在预防PEP方面的疗效.
- 评估直肠印梅他辛对出血并发症的安全性.
- 根据患者的风险和脏支架等并发干预措施来探索有效性的变化.
主要方法:
- 对随机对照试验 (RCT) 的系统文献搜索,比较直肠印梅他辛与安慰剂用于PEP预防.
- 进行了随机效应元分析,元回归和子组分析.
- 使用Cochrane的ROB2和Egger的回归测试来评估偏差的风险.
主要成果:
- 在15个RCT (4962名患者) 中,与安慰剂相比,直肠印美显著降低了PEP发生率 (RR:0. 58;P < 0. 01).
- 没有观察到出血并发症的显著增加 (RR: 0. 95; P = 0. 76).
- 当印梅他辛与胰腺支架同时使用时,疗效尤为明显 (RR: 0. 4539).
结论:
- 预防性直肠印梅他辛是预防PEP的有效策略,在出血方面具有良好的安全性.
- 当与胰腺支架相结合时,直肠印梅他素的益处更为显著.
- 需要进一步的研究来探索最佳的PEP预防的联合预防策略,承认观察到的研究偏差.

Endoscopic Procedures V: ERCP
883
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Acute Pancreatitis II: Clinical Manifestations and Management
173
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.
