Investigation modalities for evaluation of esophageal clearance function
Nihon Rinsho. Japanese Journal of Clinical Medicine
|December 19, 2018
Summary
Esophageal clearance transports food via peristalsis, evaluated using manometry and barium swallow. These methods assess esophageal motility and transient lower esophageal sphincter relaxation in reflux esophagitis.
Area of Science:
- Gastroenterology
- Physiology
Background:
- Esophageal clearance is crucial for transporting food from the pharynx to the stomach.
- This process relies on peristaltic waves, initiated by swallowing.
Purpose of the Study:
- To outline the investigation modalities for evaluating esophageal clearance function.
- To highlight the role of esophageal motility and transient lower esophageal sphincter relaxation (TLESR) assessment in reflux esophagitis.
Main Methods:
- Esophageal manometry (including high-resolution manometry)
- Esophageal radiography (barium swallow)
- Esophageal scintigraphy
- Ultrasonography
- Impedance methods
- Combination with transnasal endoscopy and manometry
Main Results:
- Various investigation modalities can assess esophageal clearance.
- Quantitative assessment of esophageal motility is a key component.
- Transient lower esophageal sphincter relaxation (TLESR) is evaluated in the context of reflux esophagitis.
Conclusions:
- Multiple diagnostic tools are available for esophageal clearance evaluation.
- Manometry and barium swallow are key methods for assessing esophageal motility.
- Understanding esophageal clearance is vital for managing conditions like reflux esophagitis.

01:15Sensory Modalities
3.9K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

01:24Esophageal Varices-I: Introduction
1.5K
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

01:09Hepatic Drug Clearance: Restrictive and Nonrestrictive Clearance
514
Hepatic clearance refers to the volume of blood cleared of a drug by the liver per unit of time. It plays a crucial role in drug metabolism and elimination. While hepatic clearance is commonly estimated by subtracting renal clearance from total body clearance, other pathways, such as pulmonary or biliary clearance, may also contribute. However, these pathways are generally less significant than hepatic and renal clearance.
Most drugs undergo restrictive clearance, which is proportional to the...

01:23Renal Clearance
2.7K
The glomerular filtration rate (GFR) is a critical marker of kidney function, reflecting the efficiency of filtration by the glomeruli. Renal clearance of specific substances, such as inulin or creatinine, is commonly used to measure GFR.
Renal clearance refers to the volume of plasma cleared of a specific substance, such as creatinine, per unit of time. To measure clearance, urine samples are collected over a 24-hour period during each bladder voiding, followed by a single blood sample at the...

01:22Esophageal Perforation-I: Introduction
597
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

01:30Esophageal Strictures-I: Introduction
870
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
