Sensory Testing of the Esophagus

Abstract: Originally, 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. In the last 2 decades interest in functional esophageal disorders has increased and thus further understanding of the underlying mechanisms of esophageal pain required development of new sensory testing techniques. Balloon distension using a computerized electronic device, electrical stimulation and impedance planimetry have generated impor… Show more

“…Each method has advantages and disadvantages with regard to simplicity, reproducibility, and invasiveness. 27 Catheters used in electrical stimulation tests can be easily inserted, as they have significantly smaller diameters than barostat catheters. Thus, the degree of invasiveness is relatively low with the electrical stimulation method.…”

“…Les fibres sympathiques sensitives dispersées dans l'oesophage ont la capacité de transmettre la douleur viscérale à partir de certains nocicepteurs sensibles à l'acide chlorhydrique et à la distension mécanique [9,16,28]. Ces derniers sont retrouvés respectivement au niveau de la muqueuse (chémorécepteurs) ainsi qu'au niveau de la musculeuse et de l'adventice (mécanorécepteurs) [9]. Les fibres sympathiques nociceptives de type C et A-delta rejoignent les nerfs rachidiens après avoir quitté la chaîne sympathique et les rameaux blancs communiquants [17,32].…”

“…Les afférences viscérosensitives parasympathiques servent de façon générale à fournir des informations sur l'homéostasie oesophagienne via certains mécanorécepteurs et récepteurs polymodaux retrouvés au niveau de la musculeuse et de la muqueuse [32]. Des études récentes effectuées chez l'animal semblent suggérer que le nerf vague serait aussi impliqué dans la transmission d'influx nociceptifs provenant de l'oesophage [9]. Yu et al ont en effet démontré que des fibres nociceptives sensibles à la distension de la musculeuse se projettent aux ganglions jugulaire et plexiforme du nerf vague chez le cochon d'Inde [33].…”

“…Importantly, it is unclear which esophageal stimulation should be used (chemical, mechanical, electric, or thermal) and what stimulus protocol to use while testing the effect of a potential pain modulator. 12 This is compounded by the fact that the rate, duration, or location of esophageal stimulation may alter perception thresholds for pain and, as a result, esophageal sensitivity assessment. 12 Consequently, it is difficult to interpret many of the esophageal stimulation studies and also place them in the proper physiological context.…”
