“…Swallowing of a liquid or a semi-liquid food product generates a thin film of product coating the pharyngeal mucosa (Levine, 1989) responsible for the dynamic profile of aroma release (Buettner et al, 2001). The influence of rheology of liquid and semi-liquid food products on aroma release and perception is an unclear and debatable issue in the literature (Hollowood et al, 2002;Cook et al, 2003;Weel et al, 2004;Saint-Eve et al, 2006).…”

After swallowing a liquid or a semi-liquid food product, a thin film responsible for the dynamic profile of aroma release coats the pharyngeal mucosa. The objective of the present article was to understand and quantify physical mechanisms explaining pharyngeal mucosa coating. An elastohydrodynamic model of swallowing was developed for Newtonian liquids that focused on the most occluded region of the pharyngeal peristaltic wave. The model took lubrication by saliva film and mucosa deformability into account. Food bolus flow rate and generated load were predicted as functions of three dimensionless variables: the dimensionless saliva flow rate, the viscosity ratio between saliva and the food bolus, and the elasticity number. Considering physiological conditions, the results were applied to predict aroma release kinetics. Two sets of conditions were distinguished. The first one was obtained when the saliva film is thin, in which case food bolus viscosity has a strong impact on mucosa coating and on flavor release. More importantly, we demonstrated the existence of a second set of conditions. It was obtained when the saliva film is thick and the food bolus coating the mucosa is very diluted by saliva during the swallowing process and the impact of its viscosity on flavor release is weak. This last phenomenon explains physically in vivo observations for Newtonian food products found in the literature. Moreover, in this case, the predicted thickness of the mix of food bolus with saliva coating the mucosa is approximately of 20 μm; value in agreement with orders of magnitude found in the literature.

“…In contrast, diverticular images with narrow communication with the esophageal lumen form a neck and are retentive, although they are small in volume; they do not contract and do not empty with swallowing. This suggests pseudodiverticulization by herniation of the mucosa and submucosa (46); they are easy to highlight radiologically even without cineradiography, being unmasked by the barium retention as additional images located outside the digestive contour, which persists after swallowing.…”

Background and Objective: Esophageal diverticulum (ED) is a relatively rare condition, characterized by high etio-and pathophysiological versatility, with an uncommon clinical impact, consequently requiring a complete and complex diagnostic evaluation, so that the therapeutic decision is "appropriate" to a specific case. The aim of the paper is, therefore, a reassessment of the diagnostic possibilities underlying the establishment of the therapeutic protocol and the available therapeutic resources, making a review of the literature, and a non-statistical retrospective analysis of cases hospitalized and operated in a tertiary center.Methods: Thus, classical investigations (upper digestive endoscopy, barium swallow) need to be correlated with complex, manometric, and imaging evaluations with direct implications in therapeutic management.Moreover, in the absence of a precise etiology, the operative indication needs to be established sparingly, with the imposition of the identification and interception of the pathophysiological mechanisms through the therapeutic gesture.

“…Secondary esophageal motility disorders can occur because of a variety of causes (collagen vascular diseases, infections, diabetes mellitus, alcoholism, endocrine diseases, neuromuscular disorders, physical and chemical agents)[712131415161718] and often have nonspecific radiographic findings. Most common collagen vascular disorders leading to esophageal motility disorder are scleroderma, mixed connective tissue disease, polymyositis, and dermatomyositis.…”

Recent years have seen a decline in number of barium procedures due to wider availability of cross sectional imaging modalities. Though use of barium esophagography/barium swallow has decreased in day to day clinical practice, it still remains a valuable test for structural and functional evaluation of esophagus. It can be performed as single or double contrast examination or as a multiphasic examination comprising upright double contrast views followed by prone single contrast views. This pictorial essay demonstrates imaging features of various esophageal diseases on barium esophagogram.
