Our hypothesis states that variceal pressure and wall tension increase dramatically during esophageal peristaltic contractions. This increase in pressure and wall tension is a natural consequence of the anatomy and physiology of the esophagus and of the esophageal venous plexus. The purpose of this study was to evaluate variceal hemodynamics during peristaltic contraction. A simultaneous ultras...
BACKGROUND AND OBJECTIVES Goldenhar's syndrome is a polymalformative condition consisting of a craniofacial dysostosis that determines difficult airway in up to 40% of cases. We described a case of a newborn with Goldenhar's syndrome with esophageal atresia and tracheoesophageal fistula who underwent repair surgery. CASE REPORT We report the case of a 24-h-old newborn with Goldenhar's syndrom...
Extrinsic afferent neurons play an essential role in both sensation and reflex control of visceral organs, but their specialized morphological peripheral endings have never been functionally identified. Extracellular recordings were made from fine nerve trunks running between the vagus nerve and esophagus of the guinea pig. Mechanoreceptors, which responded to esophageal distension, fired spont...
The purpose of this study was to evaluate the mechanical factors involved in the genesis of lower esophageal sphincter pressure. We determined the relationship between intraluminal pressure and inside diameter, estimated the ratio between the wall thickness to inside radius, and calculated the tension in the wall of the lower esophageal sphincter as a function of the inside diameter. Various de...
A 57-year-old woman was referred to the University of Michigan Hospital in July 1984 for evaluation of iron deficiency anemia. She was transfused with five units of blood and then underwent complete evaluation of her gastrointestinal tract. During double contrast examination of her upper gastrointestinal tract a 2.0 x 1.3 cm lobulated well demarcated polypoid lesion was found in the mid esophag...
