1From the Departments of General Surgery (B.Q.L., W.J.Q., M.Y., H.Y.W., L.L., B.J., Z.L.M., D.R.X., C.H.Y.), Radiology (M.C.), and Pathology (Z.X.S.), Peking University Third Hospital, 49 N Garden Rd, Haidian District, Beijing 100191, China; and Department of General Surgery, Yan'an Hospital of Traditional Chinese Medicine, Shanxi, China (B.Q.L., Q.L.).
在CT扫描上增加肠道内容衰减是预测闭环小肠道阻塞 (CL-SBO) 中肠道缩的高度特异性和可重复的标志. 这一发现有助于手术规划和风险评估.
科学领域:
- 放射学 放射学是一门学科.
- 胃肠病学 胃肠病学
- 手术瘤学手术瘤学
背景情况:
- 在封闭循环小肠阻塞 (CL-SBO) 中,术前确定肠死是手术策略和风险评估的关键.
- 关于CT成像症状与CL-SBO中的肠道缩之间的联系的研究有限.
- 准确的CT解释可以指导及时干预并改善患者的治疗结果.
研究的目的:
- 评估特定计算机断层扫描 (CT) 标志的诊断准确性,以预测不可逆转的肠死.
- 确定可靠的CT指标,用于在CL-SBO患者手术决策.
主要方法:
- 对145名经过手术确认的CL-SBO (粘附或内) 患者的回顾性分析.
- 两位放射科医生独立评估了CT标志,第三位放射科医生解决了分歧.
- 统计分析包括单变量,多变量和观察者间协议 (Cohen κ) 的评估.
主要成果:
- 增加肠道内容的衰减 (OR=45.3,P=.001) 和肠壁 (OR=15.1,P<.001) 是肠道缩的独立预测因素.
- 增加肠道含量减弱显示高特异性 (99%) 和良好的可重复性 (κ=0.84).
- 增加的肠壁衰减具有较低的特异性 (92%) 和较差的可复制性 (κ=0.59).
结论:
- 在CT上增加肠道内容的衰减是CL-SBO中预测肠道缩的高度特异和可重复的标志.
- 这一CT发现可以帮助进行手术前风险分层和CL-SBO手术规划.
- 进一步的研究可能会完善基于CT检测肠道死的标准.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
Histology of the Small Intestine
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
