1 - Esophageal Dz Flashcards
4 steps of oropharyngeal phase of swallowing
initiation
closing off nasopharynx w/ soft palate
protection of airway w/ epiglottis
clearing
little pocket behind epiglottis where food can get stuck
vallecula
when does lower esophageal sphincter open during a normal swallow?
shortly after initiation of swallow
esophagus is innervated by
vagus nerve (dorsal motor nucleus and nucleus ambiguus)
is smooth muscle inhibition greater or less as you move down the esophagus?
greater
2 broad etiologies for disordered esophageal phase of swallowing
structural abnormality
abnormal motility
globus sensation
sensation of a lump in the throat, does not actually interfere w/ swallowing though
dysphagia + odynophagia
most likely due to
infection
most important consequence of oropharyngeal swallowing problems
aspiration - may have to make NPO if this risk is too high and feed w/ NG tube or something
dx: intermittent dysphagia for solids only
esophageal ring or eosinophilic esophagitis
dx: progressive dysphagia for solids only + chronic heartburn
peptic stricture
dx: progressive dysphagia for solids only + older age + wt loss
esophageal malignancy
dx: intermittent dysphagia for solids and liquids + chest pain
diffuse esophageal spasm
dx: progressive dysphagia for solids and liquids + chronic heartburn
scleroderma
dx: progressive dysphagia for solids and liquids + bland regurg, wt loss
achalasia
dx: dysphagia + odynophagia
infection or pill esophagitis
sx of esophageal dz
hearburn, regurg, chest pain, dysphagia, odynophagia, globus sensation
hiatus hernia
top of stomach herniates up through esophageal hiatus of diaphragm
Schatzki’s ring
benign mucosal ring in the esophagus
can be treated by being stretched
acid suppression reduces recurrence
tx of achalasia
botox
pneumatic dilation (more intensive than just balloon endoscopic dilation)
Heller myotomy
tx of distal esophageal spasm
Ca channel blockers
nitrates
sildenafil
possibly botox
how does esosinophilic esophagitis appear on barium swallow?
multiple rings
how does achalasia appear on barium swallow?
bird’s beak - severe constriction at distal part with dilation of upper part
tx of eosinophilic esophagitis
elimination diet (find food that is causing reaction)
acid suppression
steroids
careful esophageal dilation if still not responsive
