手术病理学手术病理学

背景情况:

闭环小肠阻塞 (CL-SBO) 存在肠道亡的风险.
准确和早期诊断肠死是及时进行手术干预的关键.
计算机断层扫描 (CT) 是评估SBO的关键成像方式.

研究的目的:

评估定量CT方法的诊断性能和可重复性,以确定CL-SBO患者的肠道缩.

主要方法:

在2016年1月至2022年5月期间对CL-SBO患者 (粘附或内) 的回顾性分析.
根据手术发现,患者被分为死核 (n=41) 和非死核 (n=67) 组.
四种定量方法评估了减少肠壁增强;使用kappa/intraclass相关系数评估了观察者之间的一致性.

主要成果:

在动脉和门户阶段减少肠壁增强,以及它们的调整措施,与肠道缩有显著的关联.
在门口阶段调整后的小肠壁增强显示出最高的诊断性能 (AUC:0.92) 和优秀的观察者间一致性 (kappa:0.59-0.73).

结论:

Intestinal Obstruction II: Pathophysiology

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
