esophageal phase

esophageal-phargyngeal backflow

Sometimes observed on MBS and may be a symptom of number of esophageal disorders
including achalasia (failure of LES to relax), gastroesophageal reflux, tumor, stenosis

Tracheoesophageal (TE) Fistula:

Hole that develops in soft tissue common wall between trachea and esophagus, allowing food entering esophagus to flow back into trachea (may cause aspiration after swallow)

Zenker’s Diverticulum:

Side pocket that forms when pharyngeal or esophageal muscle herniates

Usually develops above UES when cricopharyngeal sphincter fails to open completely toreceive food or liquid

Pill-induced esophagitis:

Inflammation of the mucosal wall of the esophagus caused by lodged pill

Esophageal stricture

Narrowing of a segment of the esophagus where bolus may stick in the narrowed
segment, causing backflow into pharynx.

Esophageal web

Most frequently seen in from portion of upper esophagus just above or below the
cricopharyngeus muscle

Corkscrew Esophagus

Caused by repetitive contractions of esophagus

Hiatal Hernia

Outpouching of esophagus near LES

Gastroesophageal Reflux Disease (GERD)

■ Retrograde movement of gastric contents from LES into
esophagus
■ Symptoms: “heartburn,” globus sensation

Laryngopharyngeal Reflux Disease (LPRD)

Inflammatory disease of the larynx due to gastric contents
from LES reaching level of larynx

Barrett Esophagus

Thickening/inflammation of esophagus due to repeated GERD

Esophageal Cancer

Treatment: radiation, chemo, surgery

Esophageal Dysmotility

Difficulty in peristalsis

Achalasia

Failure of LES to relax
