Dysphagia itself is the subjective sensation that something isn’t moving from oropharynx to the stomach. Odynophagia is pain with swallowing. Globus is when the patient feels like something is sitting in the throat or there is a “lump in the throat”. Dr. Snyder typically distinguishes between dysphagia and globus sensation by asking how the symptom...
Dysphagia is typically separated into two broad categories: oropharyngeal and esophageal (Liu 2018). 1. Oropharyngeal Dysphagia: due to pathology above the upper esophageal sphincter (mouth, throat, pharynx) 2. Esophageal Dysphagia: due to pathology below the upper esophageal sphincter Oropharyngeal dysphagia has numerous categories for potential e...
Who should get an EGD? And who should get a modified barium study? Almost any patient with progressive dysphagia warrants an upper endoscopy as dysphagia alone is an alarm symptom warranting endoscopic evaluation (ASGE Committee 2013). For patients with oropharyngeal dysphagia- a speech consult and modified barium swallow study should be completed....
Eosinophilic esophagitis
EoE is one of the most prevalent etiologies of dysphagia. EoE is a clinical histologic diagnosis requiring 1) dysphagia and 2) endoscopic findings: >15 eosinophils per high powered field on biopsy of lower/mid or upper esophagus, furrows, rings, edema, exudates and strictures. The prevalence of EoE has increased in recent years to an estimated 1 in 1000 to 2000 (Dellon 2018). The prevalence of achalasia for comparison is 1 in 100,000. Roughly 40 to 50% of patients are histologic responders to...
Non Cardiac Chest Pain
Could this be esophageal spasm? Typically these patients need an upper endoscopy with esophageal biopsies as it could be an atypical presentation of EoE. In addition, pH reflux testing is often completed as acid reflux alone can present with an atypical spasm pain. Far less common is a true motility disorder and distal esophageal spasm. This can be identified on high resolution esophageal manometry studies. However, this is very rare with <1% of all manometry studies identified distal esophag...
