概括
标有Technetium-99m标记的Galactosyl人体血清白蛋白 (99mTc-GSA) 剪影有效地预测肝切除术后肝功能衰竭 (PHLF) 患者经历了胆道瘤的主要肝切除. 功能性肝脏残留与体重比率 (FLV_FLR-BWR) 是评估肝功能和PHLF风险的关键指标.
科学领域:
- 肝胆道手术是肝胆道的手术.
- 核医学是一种核医学.
- 在瘤学瘤学.
背景情况:
- 胆固醇症使肝功能测试复杂化,肝切除术的功能切断仍然不清楚.
- 预测肝切除术后肝衰竭 (PHLF) 对于接受大肝切除的患者至关重要.
- 恶性周胆道疾病需要对肝功能进行仔细的手术前评估.
研究的目的:
- 为了确定99mTc-GSA光束学指标,以预测大肝切除后的PHLF.
- 用99mTc-GSA.评估功能性未来肝脏残留物 (FLR) 评估的疗效.
- 建立可靠的功能参数,以指导胆道癌症患者的手术决策.
主要方法:
- 187名患者,包括81名接受肝切除术的患者,接受了手术前的99mTc-GSA光学扫描.
- 计算的参数包括功能性肝体积 (FLV),FLV_FLR-BWR和预测残留指数 (PRI).
- 通过CT确定肝脏形态体积 (MLV),并使用通用线性混合模型和ROC分析评估疗效.
主要成果:
- 患有PHLF的患者显著降低了MLV_FLR/SLV,FLV_FLR,FLV_FLR/FLV_TOTAL,FLV_FLR-BWR和PRI (P<0.05).这些患者的PHLF患者的MLV_FLR/SLV,FLV_FLR,FLV_FLR/FLV_TOTAL,FLV_FLR-BWR和PRI均显著降低 (P<0.05).
- 降低FLV_FLR-BWR是PHLF的一个独立显著预测因子 (OR 0.17;95% CI 0.05-0.53).
- 在所有测试的肝功能指标中,FLV_FLR-BWR显示了最高的ROC (0.835).
结论:
- 在手术前的99mTc-GSA光学扫描为区域性肝功能评估提供了有价值的工具.
- 功能性FLR参数可以有效地区分易患PHLF的高风险患者.
- 这种方法有助于在患有恶性周胆道瘤的患者中进行主要肝切除的手术规划.

Liver Physiology

The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

Liver Histology

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Gross Anatomy of the Liver
264
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...
