- 功能性光膜成像探针 (FLIP) 泛度测量是一种用于评估食道运动性的技术.
- 在FLIP期间控制的体积膨胀评估了食道下 (LES) 的反应.
- 了解LES生理机械状态对于诊断食道运动障碍至关重要.
研究的目的:
- 描述LES的生理机械状态.
- 使用FLIP分析LES对连续填充和排空的反应.
- 为了研究这些状态在各种食道运动障碍.
主要方法:
- 包括45名没有收缩反应的患者在FLIP (正常运动,IEM,SSc,achalasia) 和20名对照.
- 在逐步填充FLIP (60mL,70mL) 和排空 (60mL) 后,测量了LES直径和压力.
- 根据 LES 直径和压力的相对变化来定义物理力学状态.
主要成果:
- 在FLIP填充后,97%的患者出现了被动扩张.
- 在正常/IEM的86%,SSc的100%,Achalasia患者的43%,空化后对照的80%观察到被动缩短.
- 在14%的正常/IEM患者中,在57%的阿喀拉西亚患者中,在20%的对照患者中,观察到辅性放松.

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
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.

Gastric Motility
526
Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.
