Esophageal sensation is commonly assessed by barostat-assisted balloon distension (BBD) or dynamic balloon distension (DBD) technique, but their relative merits are unknown. Our aim was to compare the usefulness and tolerability of both techniques. Sixteen healthy volunteers (male/female = 6/10) randomly underwent graded esophageal balloon distensions, using either BBD (n= 8) or DBD (n= 8). BBD was performed by placing a 5-cm long highly compliant balloon attached to a barostat, and DBD by…

Diagnostic utility of the oesophageal balloon distension test in the evaluation of oesophageal chest pain
EBDT has been advocated for the evaluation of functional oesophageal noncardiac chest pain (NCCP) but its diagnostic utility remains unclear.

The Role of Esophageal Hypersensitivity in Functional Esophageal Disorders
This narrative review provides the reader with an introductory primer to the structure and function of esophageal perception, including nociception that forms the basis of the putative mechanisms that may give rise to symptoms in functional esophagal disorders.
The stimulus intensity-dependent recruitment of NaV1 subunits in action potential initiation in nerve terminals of vagal C-fibers innervating the esophagus.
The data indicate that the action potential initiation in esophageal nodose C-fibers evoked by low (innocuous) levels of esphageal distention is mediated by NaV1.7, however, the response evoking by higher (noxious)levels of esophages has a progressively increasing NaV2.7-independent component that involves multiple TTX-sensitive NaV 1s.

To determine the optimal time period after intubation when physiological observations should be recorded, it is important to know the duration of, and factors that influence, this ANS response, in both health and disease.
Gastrointestinal Interoception in Eating Disorders: Charting a New Path
Evidence of gastrointestinal interoception dysfunction in eating disorders is summarized using the alimentary tract as a guide as well as recent developments in interoceptive neuroscience and predictive processing to yield new insights into eating disorder pathophysiology.


Standardization of Barostat Procedures for Testing Smooth Muscle Tone and Sensory Thresholds in the Gastrointestinal Tract
An international working team of 13 investigators met on two occasions to develop guidelines for standardizing the procedures used to test Gastrointestinal muscle tone and sensory thresholds using a barostat, and recommends verbal descriptor scales and visual analogscales.

Sensory testing of the esophagus included the acid perfusion test and the edrophonium test, which were developed to assess patients with non-cardiac chest pain, but many studies using esophageal sensory testing are afflicted with significant design flaws, making interpretation of the results very difficult.
Edrophonium: a useful provocative test for esophageal chest pain.
Edrophonium is useful for provoking esophageal chest pain and drug specificity was assessed during cardiac catheterization, but no significant change was seen in coronary artery diameter, blood pressure, or heart rate.
Effects of gender and age on esophageal biomechanical properties and sensation
Investigating the sensory perception and the biomechanical properties of the esophagus both at the smooth muscle and the striated muscle segments in age- and gender-matched healthy subjects found that aging was associated with a larger lumen and a stiffer but less sensitive esophageal wall.
Multimodal assessment of pain in the esophagus: a new experimental model.
This model offers the possibility for controlled multimodal stimuli activating the superficial and deeper layers of the human gut and should be used in basic, clinical, and pharmacological pain studies.

Lowered oesophageal sensory thresholds in patients with symptomatic but not excess gastro-oesophageal reflux: evidence for a spectrum of visceral sensitivity in GORD.
A spectrum of visceral sensitivity in GORD is shown, with enhanced oesophageal sensation in patients with symptomatic but not excess gastro-oesophageaal reflux, suggesting that their symptoms result from a heightened perception of normal reflux events.
